I have read the book. It presents more information about game design and less about 3d Gamestudio. It is well written but if you are looking for a guied that helps you with Gamestudio itself you will do better on the official website than with this book. Again it is good as a game design book, but for the price the title is extremely misleading less than a fourth of the book is gamestudio related and is less than a retread of what you can find with the tutorials and the AUM.
