This is my old Game Design Document. I am giving this out as a sample but is not to be used or the idea taken by there as.

I am doing this for the community. Because when I first started... this was a pain.

It's a very good start. Having a solid design doc is crucial for larger games, and extremely helpful for smaller ones-even quickie casuals. For my final project in college, I put together a team and we made a small, cheesey game. It was a 3 level, 3rd person, tank game-like a 3D take on Ikari Warriors, but far less complex. Our design doc was 40 pages. Yours definitely is going in the right direction, and I could easily see it growing to 200+ pages.

Thanks for sharing. I say that my document is very unorganized right now, even with some online example.
I didn't continue it for months now.
