I'm making a design document for my game, but I don't really know how to, since I've never done one and I haven't look at any examples. Basically, what I'm doing is writing ideas in .txt files such as battleEngine.txt, replayability.txt, story.txt, sidequests.txt, characterDev.txt, etc, and then I transfer 'em to my big HTML file once I find the time.

Now, time to take a look at thoes linkies.
