In November of 2016, a small group of veteran game designers got together in a remote portion of Texas for a think tank called Project Horseshoe. Our workgroup dug deep into how design can help build meaningful relationships within games. You can read the other reports here: http://www.projecthorseshoe.com/reports/
Our group consisted of:
In many online multiplayer games, players enter as strangers and remain strangers. Due to a variety of unquestioned logistics, economic and social signalling choices, other human beings end up being treated as interchangeable, disposable or abusable. We can do better.
When we throw players into a virtual world without understanding the cascading outcomes of default human psychology, we are little better than an unethical mad scientist replicating Lord of the Flies. As game designers, we’ve been building destructive dehumanizing systems. We should take responsibility for the bullying, harassment and wasted human interactions that inevitably results.
Let’s instead design games that help strangers form positive pro-social relationships.
There’s a mature body of research going back to the 1950s concerning how to create systems and situations that facilitate positive relationship building between strangers. Given the right context, people will naturally will become acquaintances. And a smaller number will become friends.
Much of this research focuses on describing how friendship forms in observed communities. Or how an individual might go about developing friendships. We propose intentionally using these psychological insights in a highly scalable online game designs to engineer potentially millions of healthy player relationships. Many games accidentally separate players and decrease the chance of meaningful human contact. What if we design our games to be more socially meaningful?
We can’t force two people to become friends, nor should we want to. But we are in a unique position to build systems that create fertile ground for friendships to blossom. And by carefully nurturing positive relationships, we can simultaneously avoid naively birthing poisonous cesspools that actively fosters hate.
This paper cover a simple design checklist based off well supported models of friendship formation. Put it into practice and you will create games that build stronger player relationships and stronger communities. In addition to making the world a better place, your games will likely have better retention and improved monetization because you are creating value for your players that speaks to their deeply human psychological needs.
To build friendships, your game should facilitate four key factors. When these are present, friendships tend to form.
What sort of friendships does this model cover?
We define a friend as another person with whom you have a mutually beneficial long term relationship based off trust and shared values.
There’s a spectrum of friendship ranging from acquaintance to best friend. Different cultures have very different definition for what it means to be a ‘friend’. Americans for example, tend to call relatively distant acquaintances ‘friends’ while a country like Germany may reserve the term for two of three closest relationship. In this paper, we treat friendship as a spectrum that ranges from stranger all the way up to deep intimate friendship.
In particular, we focus on the transition from stranger to acquaintance. This is the step that most often falters in modern game designs.
What types of games can use this friendship model?
For the purposes of this paper, we are interested in a specific domain:
Other types of games benefit as well, but they have their own complexities that are outside the scope of this essay. Local multiplayer taps into high bandwidth interpersonal communication and often occurs between existing acquaintances. Asynchronous multiplayer relies heavily on a strong reciprocation loop to compensate for a weak sense of proximity.
The first factor to consider is Proximity. Social proximity is the likelihood of players seeing and having the opportunity to interact with one another in a game space. This space can be virtual like a chat room. Or it can be spatial like a room in a game match.
Think of proximity in terms of simple logistics. If players can’t see one another they can’t initiate the reciprocation loops and any friendship is impossible. Without proximity, friendship is impossible. In some sense this is an obvious requirement, yet in many games we create strong barriers to simply being together.
A high density game is one with a low amount of distance between players so they are likely to bump into one another. A low density game is one with a large amount of distance between players. Often we design in terms of ‘number of players’ and independently think about ‘size of map’. However, density, the ratio of these two factors, is often the key attribute to balance.
Frequent serendipitous meetings
Due to high density, people are likely to ‘randomly’ bump into one another repeatedly. This creates exposure and familiarity between strangers. Meeting the same person again and again feels like magical fate, but it is primarily the outcome of well designed statistics and logistics.
Crossing class, race and age boundaries
The single most effective method of creating friends that cross traditional social boundaries is to put two people together in close proximity. People form friendships with those that are nearby and if their choices are limited, they’ll form choices with those that would not be their instinctive (often biased) choice.
Connection to other requirements
Other players need to be identifiable. If you see someone a second time, would you know it? Names, unique clothing, identifying animation or abilities all help players understand that they are seeing the game person again and again.
A consistent persistent space that players can join and then later rejoin provides a means for players to find and associate with players that they deem worthy of friendship. There are many variations of this:
You can increase density by taking players that are spread across time and incentivize them to all show up during the same time. Many games suffer from low player density because concurrent players are spread across multiple time periods. A play session may only be 30 minutes (or less in the case of mobile) so even if you have 1000 players who play on a server, your concurrent player number would be less than 10. Think of your game in terms of concentrating player density across time.
Shared events help this situation by asking those 1000 players to all show up at 8pm on a Saturday night. Suddenly, your sparse world is full of players.
A shared event that reliably occurs every week at exactly the same time helps create that repeated interaction that is common with persistent spaces. Having a clearly published schedule of recurring events is a great method of increasing density and serendipity.
If you’ve got a matchmaking system, it can give priority to those that you’ve played with previously. Or if you have an MMO shard, the game can seed it with those that are started at roughly the same time period. The result is a group of players that are moving through the content together.
Opt-in persistent social groupings like a guild or a clan are another self selected space for those that are further along in their friendships. It is often a greater commitment to join these groups, but the result is frequent interactions in denser social spaces.
Often we create instances or servers, fill them up with a cohort of players and then fail to remove the room when players inevitably churn out. This leads to a large number of low density servers and weaker friendship opportunities. Elastic instancing has the stated goal of maintaining an optimal density of players.
Hubs and choke points
Players move around in many games. If you create a location they need to return to or move through on a frequent basis, they tend to run into other people more often. Think about your game in terms of how players flow through it. Hubs are central areas in a hub and spoke system that players must pass through. Often utilities like stores or guild features are located in or right off of a hub area. Choke points are similar to hubs in that players flow in from a broader lower density area or set of areas through a narrow location on their way to somewhere else.
Lack of identification
Many games weaken identifying signals. For example, true friendship is impossible in a game like Journey because the identity signals are intentionally weakened. People swap in and out of a given game session without the player realizing that their partner has changed. Some MMOs have a fixed set of class art. You are a wizard or a fighter and all wizards look the game. This short circuits the player’s ability to identify their friend.
Similar to lack of identification, some systems allow users to change their identifying characteristics on a regular basis. If the primary method you use to know if you’ve played with someone is their user name, and the system allows for freedom to cheaply change that user name, other players will not be able to track changes across time.
An important psychological considerations for persistent spaces is that players should have a strong belief that they will have future interactions with the people that they see. There’s research that suggests we have two sets of social norms: One for real people and another for ‘disposable people’; those that we’ll never seen again. These behaviors may be very close in the polite individual, but they can end up being negative and dismissive. If players see others a disposable due to proximity being low and repeat encounters uncommon, they’ll tend to act worse towards strangers. This leads to a downward spiral for the much of the community.
Large group sizes
Very large group sizes greater than Dunbar’s number (80 to 150) are difficult to comprehend. The overall principle is that systems need to operate at human scales (numbers and quantities comprehensible by a biological human.) We are ultimately building systems for people and homo sapiens have strong cognitive and physical limitation that we need to take into account if we want to produce the experience we desire. Don’t fall for the engineering or marketing mindset that says bigger numbers are better. A guild system that allows for 100,000 members is functionally worse in most cases than a guild that is capped at 150 because you’ve likely reduced social density, created swaths of disposable people and generally built a system that doesn’t fit with human biological constraints.
Very dense group sizes
With dense crowds of people it is difficult to see a person, difficult to identify a person and difficult to track a person. In Realm of the Mad God, we had dozens of people piled up on top of one another. This made for a great feeling of being in a crowd, but it was hard to actually see your friends.
Many gameplay modes
When games create many gameplay modes, they create more game play surface area over which players are spread. This makes any sort of match making more difficult and results in lower concurrency for each mode.
A better pattern here is to rotate through the game modes so that everyone is playing the same mode at each point. Or tie modes to timed events. Players still get some variety, but the populations aren’t split up.
Frequent splitting of groups
In match made games, the match ends and players may be thrown into the matchmaking again. As a result they are matched with completely new players and thus any burgeoning relationship is extinguished.
Separating friends by skill
Games with a heavy skill component may match players in different skill categories. Or players that were in a cohort together are split because one player proves to be highly skillful. There are many forms of gameplay that are enjoyable to mixed skill players. Cooperative games, team vs team games, party games, games of chance or discovery, build or creative games all work. Try making one of those.
Separating friends by progress
Games that focus on leveling and power acquisition often have very large power differentials between players. If two friendly players want to play together, they may not be able to because either the newbie is so weak as to be useless to the higher level player or the higher level player gets so little reward from helping out the newbie that the friendship is the waste of their time.
Barriers to repeated play sessions
A difficult aspect for many match-based games is to get the same people to play together again a second session. This point came up repeatedly as the key challenge in forming friendships within a typical multiplayer console title. Treat putting players together for multiple matches and multiple sessions as a critical design goal.
If we automate or manipulate these proximity processes too heavily, players may feel that their friendships are artificial and therefore less valuable. Heavy handed matchmaking, ‘friend suggestions’ or automated reciprocation loops cause players to imagine that their relationship is formed for purely utilitarian (or nefarious) reasons and trust in other players drops to some utilitarian level. To be fair, this is mostly a theoretical concern since as of this writing most games encourage friendships lightly or not at all. But as our techniques become more broadly practiced, this issue is worth watching out for.
The second factor to pay attention to in our friendship formation model is similarity. Similarity is how closely we share various aspects of our personality and background with another person. The more similar one person is to another, the more likely a friendship will be initiated. On first sort, we judge another person based off their visible traits, their affiliation with known social groups and any values we infer based off our stereotypes. With increased contact, we also filter by communication style and personality (see OCEAN).
If social proximity is the barest logistical necessity to form a friendship, similarity is the the criteria by which we decide who we will invest in further out of all currently available options. We can only invest in so many friendships so we filter out dissimilar people. Without similarity, friendship is possible but unlikely.
If you believe in the value of multiculturalism or other philosophies that celebrate human variety, this topic may raise an eyebrow. However, people’s reliance on similarity to filter others is one of the more strongly reported effects across decades of study. However, we see this as a tool to create rich social tapestries from complementary backgrounds and not some preordained reinforcement of the current social order. Designers in virtual environments have immense control over what players see as similar. We should use that power to mold the societies we desire.
Similarity lowers the cost of social negotiation
Shared contexts, values, and identities bring along with them social assumptions, common language/vocabulary, and models for interaction. It is easier and quicker to negotiation a cooperative, mutually beneficial set of norms if two entities share a strong common base.
Perceived similarity matters more than actual similarity
Humans are remarkably poor judges of others. So they tend to rely on superficial details to determine if someone is actually similar. In studies, this perceived similarity is a greater predictor of long term friendship than objective measurements of similarity.
Similarity in virtual environments can be generated In the real world, similarities are often difficult to change. Players bring along much of human history when it comes to various religious, racial and language differences. Surfacing that baggage immediately typically results in players using it to filter out possible friends.
Luckily, in virtual social spaces, the specific simulated cues that each player sees can be intelligently curated, often on a per player basis. The biases of the real world need not damage a first impression inside your game.
Self reports are often highly inaccurate
The traits that people say they look for in a friend are rarely what they actually use to filter out potential candidates. For example, comparable physical attractiveness and comparable intelligence correlates highly with friendship formation attempts. However, polite society looks down on stating that you are friends with someone in large part because they are devastatingly handsome. Much of the machinery of detecting and acting upon similarity is either sub-conscious or impolite to discuss publicly.
The earliest element players latch onto visual similarity. Titles, achievements, badges, equipment, names all work. Think of your similarity signals in terms of depth engagement.
Faction Identity and Conflict
A shared tribe create a strong feeling of acceptance. All social groups are composed of a core shared identity, a boundary that define who is outside the group and a set of others who are known to be outside the group.
The result of a strong tribal identity with a clearly defined Other often results in strong friendship formation. They clearly understand who they could make friends. And they have clear reasons to build those friendship in the face of an organized adversary that would swamp an unconnected individual.
Note that factions lead to some of the ugliest aspects of human culture. The very aspects that make tribes a powerful organizing forces also result in hideous abuse and bullying of those they dehumanize. At potential fix is to use AI opponents in a PvE conflict. Or in survival type games, use environmental obstacles. Often it is better to Other a digital illusion than a real human being.
A shared experience also triggers similarity. For example, when players go through a boot camp or hazing ritual as an introductory experience, they can refer to that as a common moment. In an MMO, players might go through a particularly difficult dungeon and wear a token from it as a sign of pride. The higher the cost of the hazing, the more long term the resulting self identification. There’s an element of cognitive dissonance at work. A player thinks “If I invested in X, it must have been worth it.”
Hard-fought matches, difficult raids, long periods spent grinding or leveling all can work as shared experiences. Near-wins are more emotionally intense than a clear win. Brutal losses can also create definitive bonding experiences. Many religions use repeated stories of shared persecution that function as a means of increased bonding between members.
Players who are players the same class or role within a game have a potential affinity. Or players that are on the same quest or have a shared public goal. In the game Realm of the Mad God, bonding was often as simple as two players shooting at the same enemy.
Humans look to other humans when determining how they should act. And most of the time, they give greater weight to those members of their community that have high status, aka celebrities or leaders. By highlighting celebrities within your game, you create a template for players to to compare both themselves and strangers to.
Two things will happen. Players will start to conform to the ideals shown by the celebrities. And they’ll see others that conform in a positive light. Essentially the celebrities create a beacon of artificial similarity.
Surface real world similarity can lead to premature disclosure For example, highlighting that a player is a woman in real life might result in a spike in abuse inside the game. The intent may be to encourage women to find other women, but if it occurs too early in a relationship, the overall impact is negative. See section 4 on Disclosure for more details.
Exclusionary group dynamics can calcify and reinforce the negative consequences of othering. Systems that create homogenous groups in opposition to other groups result in the following issues.
Our third factor in friendship formation is Reciprocity. Reciprocity is fundamentally about using iterative exchange to negotiate social norms and build trust. If Proximity and Similarity are filters on who becomes friends, Reciprocity is the mechanical engine that make friendship function.
Any reciprocation loop can be analyzed as a simple turn-based game between two players. Use these steps to talk about the reciprocation loops in your game.
Player A moves first
Player B responds
That’s a single iteration. Reciprocation loops are typically repeated multiple times, accumulating economic and social capital to both parties. Learn to see them. Walk through them step by step to diagnose exactly where your social loops are failing.
Exchange is substantially non-material in nature
The language of reciprocity comes from the world of economics. One might imagine that friend formation is reduced to a merely capitalist construct of exchanging material good and weath. Nothing could be further from the truth.
A valid reciprocation loop could include exchange of any of the following:
Medium of exchange
In order for reciprocity to function, there must be a medium of exchange, there must be a bidirectional flow between both parties. This covers a huge range of possible interactions.
Both sides need to feel that they benefit from the relationship, if not short term, at least over the long haul. This need not actually be factually true. See asymmetry below.
Friendships fail when exchanges aren’t appropriately reciprocated
Each time an overture is made to another person and that overture is not returned, the relationship between those two becomes more distant. A failed reciprocation can take multiple forms
You need to design unreciprocated exchanges as much as you need to design reciprocated exchanges.
You also need to consider that human find making overtures risky and rejection emotionally painful. We are wired to form friendship and when we are rejected, it is one of the deepest cuts a person can experience. So when you design for failure, consider how to soften those failures. Consider tools like: Kindness-focused language in feedback dialogs, reframing the rejection, deniability or immediately redirecting to other relationship opportunities.
The good news is that lapsed friendships that lack negative exchanges are easier to restart than new friendships. You have a common base of social norms already negotiated. This acts like a foundation of similarity in boosting re-engagement of the reciprocation loop.
Self reporting is biased
This is a tricky thing to ask friends directly about economic aspects of their relationship. Friends tend to downplay any short term or medium term benefits so as not to jeopardize long term relations. Think of it in terms of game theory using the following strategies:
This dynamic substantially biases any self reporting around friendship.
Symmetry and asymmetry
When friends describe their friendships, they take great pains to couch them as symmetrical. How one person benefits is always equal to how another person benefit. Due to the fact that self reporting on friendship is biased, our model of how friendships should be balanced is highly questionable.
Many social relations and exchanges are in fact inherently asymmetrical but reciprocal (parent/child, student/teacher, etc.). Many friendships are initiated by low status individuals seeking a relationship with a higher status individual.
Escalation of costs as friendship deepens
Friendships start out with very low cost overtures and then as each exchanges is reciprocated, the average cost increases.
This makes sense from an investment perspective. Early on, a person doesn’t know if the stranger will reciprocate. It makes economic sense to invest in many very low cost exchanges in the hopes that one of them will pay off. If most of them fail, it is fine since the cost isn’t high.
Later on, a person has established a history of reciprocation. They can be relatively confident that a long term associate will respond in a predictable fashion even if the exchange is of higher value.
Some friendships eventually falter as the cost of each exchange grows too high. But some will continue escalating to the point where nearly no cost is too much. This is seen in marriages, families, and some long term friendships.
Limited number of deep friendships
Since deep friendship come with expensive long term reciprocation loops, most people can only afford a limited number. Dunbar suggest that there are biological limits on how many people we can form relationship with and that these cluster in ever decreasing circles of friends.
Pick which groups you are designing for.
In a game with spatial positioning of an avatar (like Diablo or any FPS), the mere act of trying to stay close creates an early stage reciprocation loop. A player moves to a location. This is an invitation. Another player responds by moving in the same direction. Such move and response actions are very low cost on the part of the players so they aren’t risking much by engaging. This is the primary form of reciprocation in a stranger-friendly game like Journey.
In games with rotation, players can also face one another. This is another social gesture that forms an early reciprocation loop.
Emotes or signalling
Games often include emotions like a wave or dance animation. One player will start with a gesture and other nearby players will either repeat the gesture or iterate on it with some contextually interesting variation. This may turn into a synchronized dance session or a private emote-based language that was negotiated over multiple play session.
Chat is one of the richest methods of building social reciprocity. By tapping into language, chat enable socializing, humor, information exchange, the establishment and reinforcement of norms.
Beware premature disclosure (see disclosure below)
Exchanging virtual goods allows for a wide range of material economic transactions. Players can become a reliable supplier or a reliable purchaser. In our capitalist culture, this form of relationship is familiar to many and thus players easily fall into the appropriate roles. Trade also opens up gifting and twinking, two practices in which virtual goods are exchanged for status or goodwill but not currency.
Negotiation heavy trade such as barter is often as much about having a conversation that builds a social relationship as it is about economic efficiency. Be aware that highly efficient, low conversation trade systems such as auction houses can actively remove reciprocation loops from a game and thus damage the social foundation of your title.
Mutual Support When players can help out other players, they will often fall into patterns of reciprocal helping one another. One player covering another as they rush a point. In turn that player is healed by the person they helped. This tit-for-tat occurs even when players have symmetrical abilities.
An extension of mutual support is creating specialization for each player. Unique roles that create dependencies result in reciprocation loops. The MMO trinity of Healer, Tank, DPS class naturally clump together in order to increase their overall efficiency.
You can also build asymmetric hierarchies of mutual dependency. The MMO Asheron’s Call implemented a system where new players could declare their allegiance to more experienced players in return for help within the game. This created an improved new user experience and in return, the patrons earned a portion of their vassal’s experience. The patrons could in turn be vassals of higher patrons and everyone had a huge impetus to ensure that those below them did well. (http://asheron.wikia.com/wiki/Allegiance)
In the Xbox version of Shadowrun, players could resurrect dead players and earn a portion of their kills. However if the patron player died, all resurrected vassals would also die.
Face to Face interaction
In many real world studies simply being in the same space isn’t enough. You need to see another person’s face and be able to respond via glance or micro-facial expressions. This is not typically captured in games, but it likely will start to show up as VR and facial scanning technologies become more prevalent.
Zero Sum interactions
When there are limited resources in play, a player is forced to choose between spending a resource on a relationship or keeping it for themselves. Early in a relationship, the perceived cost and sense of loss aversion makes players selfish so they are less likely to initiate experiments. Instead use non-zero sum interactions early on in player relationships and carefully introduce low cost zero sum interactions once players have formed stronger bonds.
Ideally, zero sum interactions are opt-in and used as an explicit means of taking a relationship to a new level. For example, a player might choose to pay a fee to help level up a guild. The currency used for the fee is useful elsewhere for selfish purchases so the player ends up signaling their sacrifice and dedication to the group above their individual needs.
Trade scamming In systems that allow the trade of material goods, be wary of tempting players to scam one another. Players with weak bonds will see an unsecured trade as an opportunity break trade promises by taking something without giving a promised item in return. This reduces trust in the environment and makes it difficult for all players to form friendships.
A better system is a secure trade window that requires both players to confirm their promise and then reliably automates the exchange in the background. Ask yourself: Do the designed methods of player interaction facilitate trust? Do they protect against the bad actor’s worst instincts?
Lack of predictability
The bigger picture here is that good social norms, the foundation of friendships, rely on predictability. We build a model of how another person will interact and then base complex and expensive plans how know that person will reliably react as expected in a given context. When player behavior is encouraged to be random or unreliable, it is much harder for players to form social norms. You perform a gesture toward another player and get something random back instead of converging on a predictable social pattern.
For example, if your guild just killed a huge boss, there might be a social norm that you divide the loot. However, the system is left open ended and instead a single player takes the loot and leaves. The very player freedom that exists at that decision point results in highly unpredictable outcomes. Some games can survive this (games like Eve have various forms of community censure that turn turncoats into economic and social pariahs). Most games treat these moments as incidental social friction not worth polishing out. However, these ‘minor’ issues slowly poisons the whole community’s ability to make deep long term friendships.
Extreme power differentials
In many leveling-based system a large power gap forms between new players and old players. This economically segregates communities and in extreme examples there is nothing that a powerful player needs or wants from a low power player. The game design has created an high economic barrier between two humans that is totally artificial and unnecessary.
A good tool for solving issues like this is to ensure opportunities for economic and social dependency between any player in the game independent of power level. Create ties between players that make it beneficial to become friends. Hunt down and eradicate all systems that force players to dismiss one another as useless.
Over designing for freeloaders
A freeloader is a player that benefits from a community without contributing materially to its success. American culture specifically puts a large amount of effort into reducing freeloaders, often at the expense of community. By policing and punishing the few, the community becomes more selfish and less likely to form positive friendships.
Most community systems, especially ones based on non-zero sum resources, are remarkably stable in the face of moderate free-loading. Players may complain due to their existing cultural biases, but the end result is a stable and happy society. Ask yourself if the freeloaders are actively hurting other players. If they are, see if you can shift the design toward non-zero sum interactions. If they aren’t, feel free to ignore the problem and stop wasting precious design cycles on a non-problem.
High initial interaction costs
If an early interaction is too expensive, players won’t initiate the reciprocation loop. One solution is that the system can pay the cost early on to prime the pump. For example, social games allowed players to give gifts to other player, yet those gifts cost the giver nothing. They were created from thin air.
You do need to be careful as then people can think that they are being paid to be friends. When priming the reciprocation pump, Give the absolutely minimal, non-distorting incentives. Slowly increase what how much the system subsidizes that first interaction and look for behavior shifts at each cost increment.
Our final factor in friendship formation is safe disclosure. As players get deeper into a relationship, the nature of the reciprocation loops change from superficial mirroring to riskier trust building interactions. Key to the creation of deep friendships is the ability to friends to disclose new or secret information to another person.
Games that lack the tools for disclosing personal info between two people will never facilitate deep relationships. They may never even facilitate shallow relationships since players see that there will never be a long term future for any relationship they form in the game. However, disclosure is a highly risky action and teams will often try to cut it from their designs. Sharing information before a relationship is strong enough can result in broken or antagonistic relationships.
Risk is inherent to disclosure
When a person discloses personal information to another player, there’s always the chance it will break the relationship. Up until this point, players have typically been performing low cost, non-zero sum interactions that are tightly constrained by game systems or social convention. Personal information brings in external history, gender, age, religion, race, values and other delicate factors that may cause the other player to fail to reciprocate or otherwise pull back from the relationship.
If failure to reciprocate hurts emotionally, failure to reciprocate a personal disclosure hurts substantially more. Disclosure is a laying bare of the soul for many and the fear of rejection is immense. If your game moves relationships to this point, you are making more than mere entertainment. Your game facilitates moments that uplift or scar players in formative ways.
What constitutes disclosure is highly specific to a given person and relationship
The exact contents of a ‘disclosure’ depends on what might threaten a specific relationship at a specific stage with a specific set of participants. So we are dealing with an ill defined concept. However, the participants have a refined sense of what constitutes a disclosure so it is best to let them decide what to disclose and when.
Rich communication tools
The concepts involved in disclosure cover a huge breadth of the human experience. Emotes aren’t enough. To enable relationship building levels of disclosure you need to give players rich communication channels.
There’s substantial discussion within many design teams on whether or not to include chat. The costs are easy to list. Chat that happens too early in a relationship can trigger unpleasant early disclosure and abuse. It can be used to spam players. Children using chat are at risk of being contacted by sexual predators. There are legal and moral considerations. Developers need expensive moderators or filters to manage these downsides. Many modern teams look at this list and run as far away as possible.
However, when you cut out chat, you are gutting your long term community. Players will remain strangers and never form long term bonds with one another. Every relationship is at best like a game of Journey where anonymous people have fleeting encounters that never result in any long term impact or friendship. Remove chat and you remove 95% of all positive social behavior.
When we build human systems, we should be wary of building systems that filter out our humanity.
Luckily there are ways to have your cake and eat it too.
Quiet Opportunities to Talk
Relaxed environments where players are doing some low intensity activity will naturally result in players chatting with one another. In action games, players are often alway highly engaged with the moment to moment gameplay. There’s no space to chat. As a designer, you need to explicitly carve out these slower moments in your game pacing.
Common examples include
Mechanics that encourage disclosure
Simple interactions derived from party games can provide people with personal information about yourself like humor, status, competence, history, etc. After all, a party game is just a mechanic to encourage personal disclosure.
Mechanics that loosen inhibitions
These are less common in computer games, but very common in real-life
System often discloses information about a person before they’re ready to share that information. The designers often think they are being helpful, but in reality they are forcing reciprocation loop to jump to an advanced stage before trust is built. The result is typically highly negative interactions between strangers.
When a player doesn’t have trust built up with another person, they use any subtle clues to activate stereotypes. Stereotypes aren’t inherently bad; they are merely pre-existing schema that are used in the place of actual experience to quickly determine how to act. However, negative stereotypes end up destroying opportunities to create friendships based off personal experiences with another person.
Example of premature disclosure
When a user discloses or has information disclosed about themselves, it may in turn expose any dissimilarities they may have their current friends. This can cause the friends to rethink the relationship.
Bringing in non in-game similarities or relying on default real world similarities
Disclosing non in-game or real world similarities and assuming that they will carry the same weight in the game as they do outside of it
So far we’ve considered a lot of theory about how friendship works and how it might be encouraged within a game. However, in modern game development, it is not enough to theorize and then build something. We also need to measure if we’ve achieved our friendship goals. And then when we inevitably realize we’ve missed the mark, we can use the tools covered in previous sections to iterate towards a better state.
This leads to a vexing question: What friendship metrics can we measure across our games?
We want to measure behaviors that may indicate a ‘friendly’ relationship between players in multiplayer games. Because we want these metrics to apply to most games, we will avoid ‘in-game’ metrics, which would have to be customized to the specific design of the game.
People playing together.
Repeated co-play experience
People playing together after having played together in a previous play session. We’ll refer to the first co-play as co-play(1) and the second as co-play(2). This extends up to co-play(N).
Behaviors that imply an attempt to initiate or lengthen a co-play experience, or that may lead to a co-play experience in the future.
The challenge of strangers
For most commercial games, marketing campaigns used to acquire customers end up bringing in mostly strangers. So any friendship systems need to be tuned at launch to deal with large populations of people who don’t know one another.
There are methods of importing friends into a game but often the “Friend Graph” in a social network like Facebook maps very poorly onto the “Activity Graph” of a game, especially a new game.
The challenge of Co-play(2)
Looking across many games (and decades of design experience shared between all the authors) we observed a key challenge: Getting players to go from Co-play(1) to Co-play(2). Matchmaking creates co-play(1) with strangers very well; the hard part is getting people who played together once, to play together another time.
Existing design solutions are weak and teams rarely if ever measure this critical statistic.
How much ‘friendship’ is happening in the game?
This represents an overall metric of ‘how much repeated co-play’ is happening in a game. This metric applies more easily to discrete session-based games (Call of Duty match) than larger game experiences where players may be present but not co-playing (different WoW shards; same WoW shard but different zones). A way of quantifying this:
Note: these metrics assume that players are repeatedly playing together intentionally, and were not put together by the system repeatedly.
Measures for pre-cursors of “intentional co-play”
Beyond the above binary metric (intentional co-play: Yes/No), there are some useful pre-cursor metrics for likelihood of intentional co-play in the future:
Examples of ‘Friendship’ behavior metrics, in game
Because in-game ‘friendship’ behaviors are specific to the game design itself, it isn’t possible to do a framework that is complete. The list of metrics below is intended to be examples for how to do that.
“Friendship” systems deal with potentially intense emotional territory for players. The concepts we discuss in this paper should be treated with care. You are dealing with real humans and real emotional outcomes.
Most friendships formed in games will only be acquaintances
We use the word ‘friend’ but in truth the chances of making a deep friend in a game are very slight. We simply don’t have the mental bandwidth (see Dunbar’s groups) to have that many deep friends. So more likely is that our games are creating shallow networks of friendly acquaintances. However, think of the game as building a friendship funnel that players progress through. It isn’t a bad thing if only a few make it through to each deeper stage of friendship as long as some make it through.
Players may grow wary of overt manipulation
People dislike other people telling them they should be friends or pushing them towards friendship. Software can tell players things about themselves they don’t really want to know. For example, don’t have software define things like a marriage system and then tell two people they should be married. Instead, create opt in systems that encourage buddy behavior. Then give them tools to create ceremonies or the ability to mutually opt into a public badge that say ‘married’.
Asheron’s Call encouraged aggressively trying to recruit a lot of people hoping some of them stick. Backlash risk of this is once newbie finds out what other person was getting in return. “Did you just want me because I’m rich?” causes you to question other relationships. People smell out rubber bands. Create plausible deniability of purely economic behavior when encouraging friendships.
The relationship between behavior and affects
If you have two people who communicate a lot, it could be constant fighting! Be wary of numbers going up if you don’t track why they are going up. The classic example of this in modern times is the dramatic collapse of games at Zynga even though internally key metrics were increasing.
Grief-test your systems
The systems that help people form powerful friendships are very open to abuse. The need for disclosure in particular causes issues, but most of the anti-patterns listed above have some elements of griefing or abuse. Assume players will attempt bad behaviors and have plans in place for when this occurs. If your systems assume humans are always angels, you encourage their demons.
We believe two things when we discuss friendships:
To make friends, you need multiple people, a reason to bring them together and some form of repeated mutually beneficial interaction. Multiplayer games have all these elements. Every piece of a game can be designed to remove walls and build social connections. What an opporutnity!
Often we think of computer games as a single player medium for storytelling or some other evocative experience We put games in the same category as books, movies, comics, etc. However, it is also interesting to think of games as intentional human processes; rule-based machines composed of living, breathing, growing people. They operate on the same scale as sports, religions and governments. Such engineered human processes can help players thrive in designed virtual spaces and ultimately in their real lives.
As game designers, this is one of our great powers and responsibilities. We design these machines. We are responsible for growth and nurturing of the machine’s players and communities that they form. The human process of friendship formation is an essential game design tool. Wield it wisely.
Early theory of friendship formation
Festinger, L., Schachter, S., Back, K., (1950) "The Spatial Ecology of Group Formation", in L. Festinger, S. Schachter, & K. Back (eds.), Social Pressure in Informal Groups, 1950. Chapter 4.
Why do we form friendships
“From an evolutionary perspective, friendships may be seen as an unnecessary and costly relationship that involves altruism to a non-kin, non-mate individual who may contribute little to an individual’s reproductive success.”

Friend graphs are often non-bidirectional. However, they tend to be presented as equitable in order to preserve the network for future opportunities.
Social Penetration Theory
“As relationships develop, they penetrate deeper and deeper into private and personal matters. This exposes vulnerabilities, so trust has to be developed along the way.”
“In the familiarity of strong ties we use simple restricted codes, where much is implicit and taken for granted. In communicating through the weak ties, we need more explicit elaborated codes for meaning to be fully communicated. When elaborating, we have more scope for creativity and the thought that it stimulates makes innovation more likely. The more weak ties we have, the more connected to the world we are and are more likely to receive important information about ideas, threats and opportunities in time to respond to them. Societies and social systems that have more weak ties are more likely to be dynamic and innovative. If the system is mostly made up of strong ties, then it will be fragmented and uncoordinated.”
Selection of friends based off Big 5 personality factors
“...individuals high on Agreeableness tended to be selected more as friends. In addition, individuals tended to select friends with similar levels of Agreeableness, Extraversion, and Openness.”
