There are so many aspects to a game that when you’re designing one, you don’t think about them all. That’s where a game design document comes in handy. Creating these really helped by forcing me to consider all of the features and how they should integrate together.
What I did with these was print out all the pages and physically write on them. Actually writing it down, I feel, concretes that version of the idea. Otherwise it’s still floating around half-formed. Also, I’m kinda old-school (*laughs* so old-school now is writing instead of typing? Suddenly feel like I’m old! Nooooooooooooo) in the fact that I like writing with pen & paper rather than typing. Crossing out words and using arrows to point everywhere to show my entangled web of ideas – that’s the way I like playing and working with them.
Below are two templates for game design documents in different file formats. You are welcome to use them as you like.
