Not that this book is completely terrible, but the content is lacking and it's just not very informative or attractive.
As with most art books, it gives an example of a certain aspect that covers 1 page. That is nowhere near enough information to dedicate to an entire topic. That being said, it gives you some nice information on various job positions in the gaming world (which you could just google). There are some unique aspects and perspectives discussed on the game development, but they are too few and far between to justify the purchase of this book.
Also, the topics are immensely broad. Only a third of this *short* book is dedicated to actual drawing. Most of the rest of it is for 3d modeling which I have no interest in doing, nor have the programs necessary to even follow along or practice anything described. This book also lacks any information on getting into the industry, what you need, what you should work towards, who you should contact. Nothing. It's just a vague collection of thoughts from the author's point of view. For example, he discusses the process of making a game. This is what the director says, this is what the artist draws, this is what the animator renders, etc. This is common sense and again, you could just google that information. There's nothing worthwhile here.
Also, the artwork shown in this book is really outdated and kind of unappealing. The pencil drawings and concepts the artist put in the book were fine, but the 3d models and environments were HORRIBLE. Think the original Doom's graphics.
I can't really hate the author that much because it's not his fault alone but this book as a collaborative effort of multiple people just fails miserably. If you really want to cover all those subjects, do it in a larger book that is able to go into great detail. This tiny 170ish page book can't do that. It's just too broad. I can't even use this book as a source for inspiration when coming up with concepts because the artwork is sub-par.
I highly recommend spending your money on either an art book like "the art of (insert whatever game you like here)" for creative inspiration or if you really want to know about the gaming industry and all you need to prepare your portfolio and to actually LAND A JOB in it, I suggest you purchase "How to Become a Video Game Artist: The Insider's Guide to Landing a Job in the Gaming World." by Sam R. Kennedy. He has his crap together and covers subjects in a clear, precise way. Not to mention actually helps you get a job in the field all while displaying infinitely better artwork.
