I organized my document as follows (It's a race game):

  • Game Objective
  • Vehicle and Racing
  • Racetrack
  • Opponents
  • Weapons
  • Powerups
  • Some technical info


All gameplay elements will be explained like this.

I still have to add some information about the menu's and game states.

Is this enough or do I need to put more detail in it?
Sounds like a very comprehensive document. Should be more than enough from what you've said.
