Taken from excerpts from “The Anatomy of a Design Document” By Tim Ryan
This is general outline you should follow when submitting you game concept. Remember, keep it simple and easy for others to understand as it will be important to showcase it well at PAX Prime and to get votes! -The Next Level
The game concept should include the following features:
Brief Introduction: The introduction to your game concept contains what are probably the most important words in the document - these words will sell the document to the reader. In one sentence, try to describe the game in an excited manner. Include the title, genre, direction, setting, edge, platform, and any other meaningful bits of information that cannot wait until the next sentence. The edge is what’s going to set this game apart from the other games in the genre. For example:.
Brief Description: In a few paragraphs or a page, describe the game to the readers as if they are the players. Use the second-person perspective — “you.” Try to make this section an exciting narrative of the player’s experience. Encompass all the key elements that define the core game play by describing exactly what the player does and sees. Avoid specifics such as mouse-clicks and keystrokes, but don’t be too vague. You want the readers to become the player’s character.
Key features: Your game concept’s key features section is a bullet point list of items that will set this game apart from others and provide goals to which the subsequent documentation and implementation should aspire. It’s a summary of the features alluded to in the description. These bullet points are what would appear on the back of the game box or on a sell sheet, but include some supporting details. For example:
Genre: In a few words, define the game genre and flavor. Use existing games’ classifications from magazines and awards as a guide. For example, you could choose one of the following: sports, real-time strategy, first-person shooter, puzzle, racing simulation, adventure, role-playing game, flight simulation, racing shooter, god simulation, strategy, action-strategy, turn-based strategy, side-scrolling shooter, edutainment, or flight shooter. Then you can refine your game’s niche genre with these or other words for flavor: modern, WWII, alternate reality, post-apocalyptic, futuristic, sci-fi, fantasy, medieval, ancient, space, cyberpunk, and so on.
Platform(s): In a few words, list the target platform(s). If you think the game concept is applicable to multiple platforms, you should also indicate which platform is preferred or initial. If you intend multiplayer support on the Internet, indicate that as well.
Concept Art: You should have already submitted your main submission concept art, however if you would like to submit more you may. A little bit of art helps sell the idea and puts the readers in the right frame of mind. Use art to convey unique or complex ideas.
