Guidelines for the Game Proposal

A game proposal is a formal project proposal used to secure funding and resources for a game development project. As a game proposal takes time (and therefore, money) to do correctly, it should only be developed for promising game concepts.

The proposal is an expansion upon the game concept. Writing a proposal may involve gathering feedback and information from other departments, especially the marketing department (if it exists). You may need your marketing department to perform some market research and analysis on the concept. If the game requires licensing, you may need your finance and legal departments to investigate the availability and costs involved in securing the license.

The programming staff, typically senior programmers or the technical director, should perform an initial technical evaluation of the concept. They should comment on the technical feasibility of the concept and the programming areas that may require research. They should assess the risks and major tasks in the project and suggest solutions and alternatives. They should give a rough estimate as to the required research and development time and resources.

The game proposal should include a revised version of the game concept. Technical, marketing, and finance feedback to the concept document might force you to scale back the concept. It might also suggest modifying or adding features. These changes should not take anyone by surprise, as this is the first time that the concept has been subjected to major criticism and the collaborative process. Giving copies of the feedback and analysis to the director of development (or whoever asked for the game proposal) before they are folded into the game proposal or effect changes in the concept is a good idea. This process not only provides written confirmation that the concept has been reviewed by certain people or departments, but it arms the director with the knowledge to veto, alter, or otherwise approve any proposed changes.

The game proposal includes the following features:

  • Revised game concept (preceding)
  • Market analysis
  • Technical analysis
  • Legal analysis (if applicable)
  • Cost and revenue projections
  • Art

Market analysis: The marketing department and/or a market research firm, assuming your company can afford it, should compile this information. If you are compiling this information yourself, you should try to avoid pure guesses on numbers. Look for info on the Internet (www.gamestats.com is a good source) and use existing hits in the same genre as indicators for market performance.

  • Target market: The target market is defined by the genre and the platform, issues that have been already addressed in the concept document. You can qualify this definition by mentioning specific titles that epitomize this market. The most successful of these titles will indicate the viability and size of the market. Also mention the typical age range, gender, and any other key characteristics. If this game involves a licensed property or is a sequel, describe the existing market.

  • Top performers: List the top performers in the market. Express their sales numbers in terms of units, breaking out any notable data-disk numbers and any successful sequels. Include their ship date. You can be vague -- Q1 1998 or spring 1998. This research can go way back, so present your data in chronological order.
  • List their platforms if they vary from the platform for the proposed game. However, because the markets change depending on the platform, you should always present some title of the same genre on the target platform, even if it didn't perform as well as the others. Such data may indicate a sluggishness for that particular genre of games on the platform. For example, turn-based strategy games may have great sales on the PC platform, but have terrible numbers on the Sony PlayStation. This list of top performers should indicate this discrepancy if you're doing a turn-based strategy game.

  • Feature comparison: Break down the selling features of these top performers. Compare and contrast them to the key features described in the concept document. Try to provide some specifics. For example:
  • Tactical Combat: In Command & Conquer, Dark Reign, and Myth, you order your units to attack specific targets and move to specific places or ranges for an advantage. Most units have a unique strength and weakness that become apparent during play, thus encouraging you to develop superior tactics. Tanktics has a wider variety of orders to allow you to apply superior tactics, such as capture, ram, and hit-and-run. Unit position and target selection become even more important due to terrain, movement, and range bonuses; firing arcs; and soft spots in rear- and side-hit locations. All of the units have distinct weaponry, armor, and speed to differentiate their strengths and weaknesses and encourage tactics. Not only do you learn to master these tactics over time, but you can also script these tactics into custom orders.

Technical analysis: The technical analysis should be written by a seasoned programmer, preferably the technical director or a lead programmer, and then edited and compiled into the proposal. Reviewers of this proposal will use this technical analysis to help them make their decisions. Be honest; it will save you a lot of grief in the end. Overall, this analysis should make the reviewers optimistic about the game's chance of succeeding.

  • Experimental features: Identify the features in the design that seem experimental in nature, such as untried or unproven technologies, techniques, perspectives, or other unique ideas. Do not include features that have been proven by existing games, even if they are new to the development team. For example, if the team has never developed a 3D engine, don't list it as experimental. Rather, list it in one or more of the other categories in the technical analysis section. On the other hand, if your development team is working on a 3D engine using the theoretical system of quads, then this effort should be listed as experimental. Of course, by the time you read this article, quads could be in common use.
  • Include an estimate of the time that it will take to bring the experimental feature to an evaluation state, as well as an overall time estimate for completing the feature. Experimental areas generally need more time in the schedule, so the more experimental features you list, the longer the schedule will be. While some companies shy away from such 18- to 24-month projects, many see these experiments as worthwhile investments in creating leading-edge titles. So tell it like it is, but don't forget to tell them what they will get out of it. Make them feel comfortable that the experiments will work out well.

  • Major development tasks: In a paragraph or a few bullet points, make clear the major development tasks. Use language that non-technical people can understand. Major means months of development. Give a time estimate that assumes that you have all of the resources that you'll need to accomplish the task. You could also give an estimate of the resources that you'll need. For example:

    "Artificial Intelligence Script Parser: Three to four months with two programmers. The parser reads and compiles the AI scripts into lower-level logic and instructions that are executed at run-time."

  • Risks: List any technical risks. If you don't foresee any technical risks, by all means say so. Risks are any aspect of research and development that will cause a major set back (weeks or months) if they fail. List technologies that, though they've been proven to work by competitors, your company has never developed or with which your company has little experience. List, for example, real-time strategy if your team has never developed a real-time strategy game before; or 3D rendering if this is your first foray into 3D. List any of the major development tasks mentioned previously if you perceive any risk. All untried off-the-shelf solutions (3D engines, editors, code libraries and APIs, drivers, and so on) should be listed as risks because they may end up not fulfilling your particular needs. Any development done by an outside contractor should also be listed, as that's always a big risk. When assessing risks, you should also indicate the likely impact that fixing or replacing the technology will have on the schedule. Indicate the time in weeks or months that the ship date will slip. List the time impact on specific resources. List any new resources (people, software, hardware, and so on) that would be required to fix it. This section may seem pessimistic, but it creates a comfort level for your document's reviewers - they will come away with the impression that the game implementation is under control, especially if they can perceive these risks themselves. Plus you'll have the opportunity to say, "You can't say I didn't warn you."

  • Alternatives (if any): Alternatives are suggestions for working around some of these experimental or risky features and major development tasks. By presenting alternatives, you give the reviewers options and let them make the choices. List anything that might cost more money or time than desired but might have better results, or vice versa (it may cost less money and time but it may have less desirable results). Whatever you do, be sure to spell out the pros and cons.

  • Estimated resources: List the estimated resources: employees, contractors, software, hardware, and so on. Use generic, industry-standard titles for people outside of the company: for instance, the publisher or investor who might read your document. List their time estimates in work months or weeks. Ignore actual costs (dollars), as that comes later.

  • Estimated Schedule: The schedule is an overall duration of the development cycle followed by milestone estimates, starting with the earliest possible start date, then alpha, beta, and gold master.

Thank you so much for this article Tim Ryan.

eh?

the GDD needs to include the proposal as well as the concept design documents?

why should they both be included in the game design document?

the concept design document is used to get the publishers attention, proposal is used to pitch your idea to the publisher. So I don't know why both must be included in the GDD again.



do they have to be included?

Why wouldn't they be? The proposal especially. It's the basis of the game, the "this is what we're going for" document. It's the backbone that says "Hey, we're off target on this feature" or "that feature is spot on" during the development process. And the concept design art is such an integral part of the games design process that I couldn't see it NOT being a part of the GDD. Now, mind you, chances are it be a supplement to the GDD (a concept design Bible of some sort), but it'd be a part of it none the less.

Well, expressive thoughts. This is an useful tool for novice who had never been in the industry. Simple yet well-spoken.
