This book WILL tell you:1. The location of all the eggs and gems.2. Detailed maps of every world and level, including the super bonus level. The game itself is fairly easy to beat without the book until you get to the last world. I got that far without the book. This guide is useful to have however.However, it does NOT tell you much of anything about acquiring the skill points in certain levels (not all levels have them.) I found this to be quite disappointing. If you search for "Spyro Dragon Skill Point" at Ask Jeeves one of the results is titled "SpyroHints.com Dragon News" Click on that, then 'Spyro 3,' then 'Secrets' to get that info. It is for this reason I did not give this guide 5 stars.
