This book is filled with inaccuracies. I know that it can be difficult to seperate myth and legend from historical fact when it comes to the history of electronic gaming. For example, look at the variations of the story of Pong in Andy Capp's bar. Unfortunately, even some of the captions next to pictures are wrong.
If you're looking for a book about the history of electronic gaming, I recommend The Ultimate History of Video Games (ISBN 0-7615-3643-4) by Steven L. Kent. However, inaccuracies aside, this book is good as a visual aid to supplement Kent's book. This book is filled with pictures, while Kent's book is filled with text.
Also, do not expect this book to have a very long lifespan. It is glue bound and the pages will start to fall out after repeated use.
