Overall, I like it. He mixes high level ideas with both analysis of specific games and interviews with game designers, and talks a lot about nuts and bolts. For example, there’s a chapter on the design document, and another on documentation in general. There are also two appendices of example design docs, one for a hypothetical game, the other for The Suffering. He also takes a historical perspective, analyzing Centipede and Tetris along with The Sims and GTA III.

Histogram of the number of ratings per customer

The red line is the gamma distribution fit by the method of moments. It’s way too high on the left, and way too low on the right. Can anyone think of anything better?
