The Art of Computer Game Design

When I read this, I was amazed at how insightful and relevant it was. It's a must-read if you want to design games. It's even free, so what are you waiting for?

I feel like I should be more detailed about the book, or about what it made me think, but I'm having trouble expressing myself clearly.

There are now two attempts at a more in-depth analysis or review sitting in my blog account, marked as "Draft" so nobody can see them. Neither of them is what I'm looking for.
