Like anyone else who grew up playing videogames, I have a great romance for â€śvideogame-style asymmetryâ€ť.Â What Iâ€™m referring to with â€śvideogame-style asymmetryâ€ť is a quality that games such as StarCraft or Street Fighter have, where you â€śchoose your characterâ€ť or â€śchoose your raceâ€ť before the game even begins.
This kind of asymmetry is so beloved for a number of reasons, all of which I understand on a deep level, having experienced and immersed myself in it for my entire life.Â However, after years of grappling with it, Iâ€™ve disappointingly come to realize that this kind of asymmetry is less than ideal for game design.Â I am sad to have come to this conclusion, but Iâ€™m comforted by the fact that as always, Iâ€™m only talking about guidelines for ideal game design.Â So, this doesnâ€™t mean you can never make a game with videogame-style asymmetry, it just means that if you do, you should understand the costs.
I should qualify that this is distinct from â€śinherent asymmetryâ€ť, as is the case in the childrenâ€™s game of â€śtagâ€ť (where one person is â€śitâ€ť and the other must escape),Â or even the popular videogame Counter-Strike.Â To illustrate, in Counter-Strike, one team is always â€śthe terroristsâ€ť, and they have a distinct objective.Â The other team is always â€śthe counter-terroristsâ€ť, and they always have a different objective than the terrorists.Â Itâ€™s not as though teams select whether theyâ€™d like their team to be Terrorist or Counter-Terrorist and you could end up with a mirror match or something; there are no CS â€śmatchupsâ€ť.Â And CS still has high levels of asymmetry due to the fact that you can choose your guns, which means it might be SMG versus Shotgun (although in practice, most of the time itâ€™s M4 versus AK).
Beyond that, though, There arenâ€™t many popular examples of more â€śstrongâ€ť inherent asymmetry.Â One that comes to mind is the boardgame 2 de Mayo, a two-player game wherein one player is the French, who have tons of forces pouring in from all directions on the map, and the Spanish, who have limited forces in the middle.Â They have asymmetrical amounts of power, but also asymmetrical objectives: the Spanish simply have to survive at all until the last round in order to win.
The difference between â€śinherent asymmetryâ€ť and â€śvideogame asymmetryâ€ť (maybe a better, albeit less-catchy term for it might be â€ścomponential asymmetryâ€ť) is that with inherent asymmetry, you donâ€™t get to â€śconfigure the gameâ€ť.Â Sure, you can choose who will be the French/Spanish, or you can choose who will be â€śItâ€ť in tag, but itâ€™s more like choosing who goes first than the process of selecting a character in Street Fighter.
Interestingly, each â€śmatchupâ€ť in, say, Street Fighter, should be looked at as a distinct â€śinherently asymmetrical gameâ€ť.Â So actually, when you build a game with four characters, youâ€™ve actually built ten â€śinherently asymmetricalâ€ť games in one (4 choose 2 = 6, plus 4 for the mirror matches).
With that said, please understand that this article is about videogame-style asymmetry â€“ componential asymmetry â€“ and not at all about inherent asymmetry like in 2 de Mayo.Â So, whenever you see me saying â€śasymmetryâ€ť from here on out, assume I mean â€śvideogame-style, pre-game asymmetryâ€ť, unless I specify otherwise.
Before I go about with the debunking, I should first list my general problems with asymmetry.
Based on my experience and research, the generally agreed upon opinion right now is that Videogame asymmetry is almost always a â€śplusâ€ť in game design.Â Indeed, it has many qualities that seem highly desirable, so this point of view isnâ€™t surprising, even if itâ€™s ultimately mostly wrong.
We can begin with one of the worldâ€™s most vocal champions of asymmetry, game designer David Sirlin, who has been striving to bring videogame-style asymmetry to boardgames with his games like Puzzle Strike and Yomi, as well as his game Flash Duel, which is essentially Reiner Kniziaâ€™s En Garde, but with asymmetrical characters added.Â From his Sirlin Games â€śmanifestoâ€ť page:
â€śItâ€™s boring when every player starts with the same set of moves. All my games are asymmetric, meaning you can choose from 20 characters, each with a different set of moves and powers.â€ť
While I have huge respect for David Sirlin, much of his writing, and his ability to design games (go check out Puzzle Strike if you havenâ€™t already), the first line seems to me like an obvious over-statement.Â He canâ€™t really be saying that every non-asymmetrical game is boring, can he?Â Keep in mind, Iâ€™m certainly not saying that â€śall games with asymmetry are boringâ€ť, or anything even close to that.Â Only that itâ€™s less than ideal and has problems.
Most designers donâ€™t go quite as far as to say that symmetrical games are boring, however they do generally echo the idea that asymmetrical games are â€śless boringâ€ť.Â Jon Shafer wrote an article for Gamasutra about asymmetry, which mostly echoes David Sirlinâ€™s point of view, although makes a few caveats saying â€śnotÂ allÂ gamesÂ can be asymmetricalâ€ť, with the implication being that if they could all be asymmetrical, they would of course be better for it.
Or listen to this Three Moves Ahead podcast episode, wherein Troy Goodfellow, Tom Chick, and Julian Murdock muse about asymmetry in games.Â While they donâ€™t get too deeply into theoretical specifics, the mutually agreement that â€śasymmetry is betterâ€ť is clear throughout.Â Interestingly, the most telling moment is at one point when one of them said,
â€śLast year we had Halo Wars which was asymmetrical, and End War, which was symmetrical, and End War wasâ€¦ just a better game.Â Which surprised me.â€ť
This was followed by about two or three seconds of dead air, before someone chimed in to essentially change the subject.Â Basically, itâ€™s obvious to all of them here that even if End War really was better, thatâ€™s obviously just some fluke, some bit of meaningless trivia.Â Itâ€™s surprising that a symmetrical game would be better than an asymmetrical one!
So overall, the status quo point of view is clear:Â ASYMMETRY GOOD.Â On why asymmetry is good, wellâ€¦ thatâ€™s a bit more fuzzy, although there are certainly some given reasons.Â I will now go through some of the specific reasons and debunk them.Â They are listed (roughly) in order of how common the defenses are, with Defense #1 being the most common defense.
Iâ€™m coupling â€śreplay valueâ€ť with â€śvarietyâ€ť in with this section, because I think theyâ€™re very closely related.Â Essentially the argument here is, if a game doesnâ€™t have asymmetrical forces, then itâ€™s going to get stale after awhile, because you canâ€™t try the game from a new angle with new powers or whatever.Â Or put another way, if a game does have asymmetrical forces, itâ€™s much more likely to have increased variety.
Itâ€™s easy to understand this claim.Â If you are playing Street Fighter, and youâ€™re starting to get bored playing as Ryu, well, you could always switch to Blanka, or E. Honda, or any other character, and get a different experience.
The problem is that this is a short-term solution that comes with all of the negative effects that I listed in the â€śproblemsâ€ť section of this article.Â But the real myth here is that variety / replay value can only come from asymmetry.Â You can create â€“ and people have created â€“ symmetrical games that are every bit as replayable, varied and interesting as any StarCraft or Street Fighter, but which is also way more well-balanced.
A quick example would be the great boardgame Puerto Rico, which quickly unfolds into natural, emergent asymmetry.Â Puerto Rico uses a deep, interesting system that unfolds into a wide array of interesting outcomes, combined with some very light input randomness, with nothing even close to resembling videogame asymmetry.
Thereâ€™s much talk about flavor â€“ about different asymmetrical forces â€śfeelingâ€ť different in a significant way, and the assumption is that this can only be achieved through asymmetry.Â While I agree that it certainly is achieved through well-built asymmetry, my point would simply be that any great game, symmetrical or asymmetrical, would already provide a wide range of flavors for different strategies. For instance, this bit from Jon Shaferâ€™s Gamasutra article on asymmetry:
The Zerg and Terrans could maintain their excellent art direction, but if they had basically the same units with the same abilities, only with different coats of paint, it would no longerÂ feelÂ likeÂ StarCraft. The Zerg are an organic swarm â€“ their units should be more numerous and should have unique abilities like burrowing out of the ground.
So, â€śfeelâ€ť also seems to be a major defense, and itâ€™s not just â€śthematicâ€ť feel, but also mechanical.Â I agree that the Zerg do mechanically feel different to play than the Protoss, and thatâ€™s of value.Â The question is, can that kind of â€śfeelâ€ť only be captured with asymmetry?
Unless you are speaking purely thematically, I think itâ€™s without doubt that asymmetry is not actually needed to have this kind of â€śdifferent feelâ€ť.Â Good symmetrical games have enough strategic space so that players can exhibit vastly different playstyles.Â For instance in the game of Go, playing more defensively and shooting for influence (a loose spreading of many weak stones around the board, often closer to the center) feels very different than a player who is more concerned with winning fights now and grabbing territory (and those are just two obvious examples; a more serious Go player can give you better ones, Iâ€™m sure).
Even if you look at an asymmetrical game such as StarCraft, you can already have vastly different playstyles even in a mirror match.Â Maybe in a Terran vs. Terran match, one player chooses to put a lot of pressure on with harassment, or another playstyle could involve using lots of air units, or rushing.
A great example of how to do non-asymmetrical flavor is something like heroes in Warcraft III.Â If the game was only Human vs. Human, there would still be plenty of emergent asymmetry in hero choice.Â If you get an Archmage first, and I get a Mountain King, thatâ€™s a significant difference that really feels different.Â If you get a second hero and I donâ€™t, that makes it even more different.Â And this game wasnâ€™t even designed to be single-matchup; imagine a game like that that was.
In just the way that these designers are talking about how different races or characters need to have a strong sense of â€śflavorâ€ť, taking on different strategies also needs to have a strong sense of flavor â€“ needs to feel different.Â Actually, I think that the â€śfeeling differentâ€ť is just a byproduct of them being different, which is obviously important.Â So if your game has strategies that really are different, then why do you need asymmetry?
The only remaining answer is â€śto support the theme/fantasyâ€ť â€“ to make it feel like that scene from Starship Troopers.Â Obviously, this is not a game design motivation, so it canâ€™t be used to defend asymmetryâ€™s role in ideal game design.
The idea here is that players find a character that matches their â€śplaystyleâ€ť, which we are to understand already existed on some level before the player ever played the game, and this game, being asymmetrical, allows them to express themselves more truly because of this.Â So for instance, a very aggressive or impatient player might find that a rushdown character allows him to play the way he wants, or a person who is generally pensive might prefer a more defensive character.
My counter to this one is that I simply donâ€™t even accept that this is really a thing.Â I do not think that a person necessarily comes to a game with a â€śplaystyleâ€ť before they even know how to play.Â It does not make sense that a person would have such a thing.Â It needs to be demonstrated that this actually exists.Â At what point does it develop?Â Was it there before they ever played?Â I have a hard time believing that I could have a natural playstyle in some strange abstract game that I havenâ€™t played or even heard of yet.Â I suppose I could see it happening a bit for a player in two games that are similar, like if they went from Street Fighter to Super Smash Brothers or something, but hopefully going forward, fewer games will be so similar to each other.
But even if you do somehow â€śinherentlyâ€ť have a â€śrushdown personalityâ€ť or something, a great game should have a wide range of creative strategy that allows you to express that.
Finally, though â€“ even if this phenomenon really did exist, it conflicts with getting good at a thing anyway.Â If youâ€™re trying to play optimally, you canâ€™t just keep doing what you â€śfelt like doing before you even played the gameâ€ť.Â Playing games is about the creative search for more optimal moves, and good players know to try to ignore their own biases and that often times, getting good involves doing the counter-intuitive.
This is different from variety, in that it doesnâ€™t actually care about the game experience at all.Â This simply means, on the back of your box you can brag about having â€ś50 characters!!!!â€ś, which can seem like a good thing to many people.
By â€śmany peopleâ€ť, I am mostly referring to young children, people trying to market to young children, and adults with the minds of young children.Â I donâ€™t think most decent game designers give this much credence, since itâ€™s pretty obviously stupid.
At least, on paper.Â I think that after 30 years of the more-is-better arms race, a lot of totally solid designers â€“ myself included â€“ have had their perspective a bit warped in terms of amount of content.Â Videogames are expected to have a certain amount of content to be â€śa real gameâ€ť, and asymmetry is often one of the ways that designers fulfill this quota, many times, unwittingly.Â I think we all have to take a serious self-assessment of the damage that living through the past 30 years has done to us.Â Especially since so many of us played Magic: The Gathering as kids.Â That canâ€™t have had good effects.
I also listened to a recent Game Design Roundtable podcast episode that featured Mr. Sirlin, where he mentioned that in asymmetrical games, â€śthe player really only has to learn one sideâ€ť, suggesting that that games are easier to learn, since you technically only have to learn one character to â€śplayâ€ť.
I put the words â€śplayâ€ť in quotes, because if you donâ€™t know the character youâ€™re playing against as well, then youâ€™re really just inputting moves into a black box and itâ€™s spitting out a win or a loss â€“ you canâ€™t possibly understand what youâ€™re doing or form strategies.
And unless you â€śrestrict the game to 1 or 2 charactersâ€ť, in which case the game isnâ€™t really asymmetrical, you actually have to learn all of the characters to really play.
For example, Iâ€™ve been playing a bit of League of Legends recently, largely for research purposes, but also because Iâ€™m pretty desperate for a decently well-made modern online competitive game.Â The claim that I only have to learn one character in this game is obviously pure trash â€“ Iâ€™m trying to play that way and it isnâ€™t working out so well.Â Iâ€™m frequently killed by a character ability that I had no idea existed, or I waste a key spell on a character that has a way of getting out of it, etc.
Asymmetry lets you learn how to â€ścontrol your characterâ€ť perhaps more quickly, but â€ścontrolling your characterâ€ť and â€śplaying the gameâ€ť are two different things, the latter involving â€śforming strategyâ€ť which is only possible if you know the other charactersâ€™ abilities.
I played a ton of Warcraft III back in the day, and I can tell you: arguing about different races, heroes, and units is way more fun than actually playing the game.Â I think that this statement is true or close to true for a lot of popular online multiplayer videogames.Â Arguing about â€śtier listsâ€ť and such probably takes up at least as much time as does playing the game for many players.
Then thereâ€™s stuff like â€śpopular strategiesâ€ť, where some build or set of tactics becomes well-known and copied throughout the world, and then people start to develop counter-strategies, which themselves become popular, and so on.Â This is a pretty cool thing, for sure, and an important part of a gameâ€™s â€ślifeâ€ť.
However, this isnâ€™t at all a unique thing to asymmetrical games.Â Research professional / high-level Go replays and commentaries online and youâ€™ll see that itâ€™s got all the same stuff going on as does League of Legends or StarCraft.
Thereâ€™s just one thing that comes to mind that asymmetrical games provide for a â€śmetagameâ€ť that symmetrical games donâ€™t, and itâ€™s a really ugly, horrible quality: â€ścounter-pickingâ€ť.Â You see, not only are some characters squarely better than others in asymmetrical games, but some have significantly high win rates versus specific characters.Â So, you can â€ścounter-pickâ€ť your opponent by choosing a character that is better than that character.Â This results in all kinds of weird, ugly meta-game rules, starting with a blind first pick, and then stuff like â€śthe loser gets to change character and the winner canâ€™tâ€ť.Â So, this bouncing back and forth of picking, counter-picking, and counter-counter picking is actually optimal play.Â Horrible.
Iâ€™m not saying you should never use asymmetry in your games.Â There are some real, tangible reasons to use asymmetry, itâ€™s just that almost none of them are good game design reasons.Â However, Iâ€™m willing to accept that there could be some good game design reasons out there; itâ€™s just that none of them have been used yet.
So here are some of the not game design related, but still good reasons to use asymmetry.
For one thing, asymmetrical forces can be really helpful in building a world/theme/setting, which sometimes can be of great value to a company thatâ€™s trying to get people attached to its products.
There may be some very technical thing thatâ€™s specific to your game system that no one has really seen before.Â Some have talked about using characters as difficulty modes, which is a bit weird, but could work in a party game or something.
Asymmetrical forces could be used to create a smokescreen for a lackluster game.Â Letâ€™s face it: most games we make just arenâ€™t all that great.Â Sometimes having a â€ścharacter selectâ€ť might be just the sauce you need to get people to play your game even for a little while.Â They played your game for a couple weeks, you made a sale â€“ everybodyâ€™s happy.
Or, you just want to.Â You, like me, have a great romance for asymmetrical forces, having been brought up in a world that romanticizes them.Â I understand that, and thereâ€™s a really good chance that Iâ€™ll design an asymmetrical game or two in my lifetime.
Actually, wait â€“ I made 100 Rogues, which has asymmetrical characters, didnâ€™t I?Â Huh.Â And the funny thing is, I didnâ€™t understand any of this back in 2008 when I started working on that game.Â So Iâ€™m not saying donâ€™t make asymmetrical games.Â I just want people to understand the costs and benefits of doing so.
Oh, and if you have any good counter-points, I would love for you to convert me to a pro-asymmetry position.
