  • Alter the setting of an existing game.
  • Tell a different story of an existing game.
  • Combine two or more games together.

Write a Game Design Document

A Game Design Document (GDD) is a consolidation of text, diagrams, and art, that describes your game's design.

What are the High Level Details?

  • What are the genres, goals, and features?
  • What is the art and sound direction?
  • What platform/s are you targeting? (Desktop, Console, Mobile, VR, AR)
  • Who is the Target Audience?
  • What do you want players to experience or feel?

Elaborate on the Game Design

  • Rules, game mechanics, game objects, game systems, interfaces, interactions, control schemes, and game options, game loop, progression, rewards.

Update the GDD Over the Course of Development

  • The GDD is a living document and should contain the most recent design of the game as it will serve as a reference during development.
  • But, it is very likely design will change after several sessions of prototyping, playtesting, and discussing.

Evaluate the Scope

Narrow Down the Minimum Viable Product (MVP)

  • Determine what are the essential features that makes up the game (mechanics and systems).
  • Determine the minimum mount of content that you think the game should offer (characters, levels, events, art, audio, etc).
  • Remove any Features that are not necessary for creation of the Game
  • Set the minimum amount of content that you want to be in the game.
  • If necessary, mark content you are willing to cur from the game.

Could You Make this Game?

  • Do you have the technnical skills to make the game? If not, where will you get them?
  • How long will it take to make this game?
  • Can your team execute this game idea and create a finished product in the desired production timeframe?
  • How much time and money would it take to make the game?

Avoid Design Pitfalls

Avoid Perfecting Your GDD

  • A game's design is always subject to change.
  • You don't know if a design works until you make it.
  • Start Making Your Game.

Avoid Feature Creep

  • Don't continuously add new features and content to the game's design over the course of development.
  • Focus on achieving the game's Minimum Viable Product before adding additional content.
