I waited a while to get the book because a lot of people said it was too beginner to bother with. Although I agree it is very beginner. It does delve into other than just FPS. It looks at RPG and goes into a lot of detail on constructing levels and characters. I would have to say it was very helpful (to me) and that I thought is was money well spent IMO. I have A7 but it has info that you can use in that even though it might be more geared to an earlier addition. Anyway, my 2 cents worth.
