I've never read the book, so I can't comment about the content, but by the sound of it, some of you didn't like it too much.
Here's a question - what would you like discussed in a book on game programming? At what level - beginners, intermediate or expert?
If the book was for beginners, then you couldn't get anything usable in a small amount of space (and be able to fully explain something).
Experts would have an existing knowledge of things that make it easier on the writer to use technical methods that won't make you shake your head and ask WTF.
Intermediate is great, but you start to leave out the beginners, and assume the reader has some knowledge to follow along.
So I ask again, what would you like to see in a book? How would you like to see it organized?
