The articles, or gems, included in the book cover intermediate to advanced topics in the areas of general programming, mathematics, artificial intelligence, geometry management, graphics display, and audio programming, each edited by an expert in the field. Most of the gems assume that you have a fundamental knowledge of the issues related to the topic, and get to the point quickly. As a result, on average the gems are shorter than the previous volume. Both of these things could be viewed as either positives or negatives, depending on your experience level. Regardless, almost all of the gems are well written and relevant.

Most game programming books these days come with CDs packed full of demos, source code, and other information supplementing the book. Unfortunately, the CD that comes with this book isn't one of those. It does have source code from most of the chapters, but there are very few demos and no extras (unless you count GLUT and the DX8 SDK, which I don't since you can easily get those elsewhere). However, I'd count the CD as only a minor disappointment, since the book itself is so good.

If you're serious about game development, I'd highly recommend adding Gems 2 to your library. You'll definitely find things in it that you can use.
