When More Is Too Much

This week's assignment is to write a Design Document for the game we wrote the concept document for in week 5. (We're in week 7 of 8 now) Our document should be 5 - 7 pages in length. Halfway through the project, mine was standing firm at 9 pages...WTH?

So I start talking to Kid Risk,(He ain't heavy, he's my Brother) and he says to keep it short and sweet, as noone is going to read a 20+ page doc.

I trimmed it down to 7 pages. But if my design doc is supposed to be the document designers build the game from, how am I supposed condense some hundreds of hours of gameplay into 7 pages?

Harrrumpf!!!!!
