I bought this book as a collector, not really expecting anything amazing, as most recent Pokemon guides have been very sub-par. This exceeded my expectations, and anyone looking for a step by step walkthrough through the main game will find it more than sufficiant. It has few errors that I've been able to find, and has locations for all obtainable Pokemon. My only complaint from a content standpoint is there is no guide for the Post game content, which is instead located in the sister guide, the offical pokedex. As for the quality, it looks and feels quite nice. The paper is glossy, the colors are vibrant and the bonus art that comes with the book looks great. As a collector's item I have no complaints.
