I would like your help on how to effectively write a game design document. From the templates and examples I have seen, the style of writing and the sections included can vary. I would like to know what sections you think are compulsory, such as, maybe core game play, levels etc, and any important sub sections within the sections you identified. Feel free to include any other relevant advice in writing a game design document.
For me, sections that I find important are, the mechanics section for defining how the game plays, the AI section to explain how the AI-controlled characters behave, and the contents section for defining any items and objects that the player can obtain, utilize or interact with in any way. I look forward to reading your replies
