Gamebrief was created by James Hostetler and is meant to focus development of your game with 10 questions.
Gamebrief is inspired by the design briefs graphic designers use to target and deliver effective work to clients. These questions will help you get a better grasp on your game, tools, and audience.
I suggest doing the gamebrief after brainstorming game ideas and choosing one to target. Typically, a design brief is known as a living document because it can and should change as your vision becomes clearer.
