Actually, it's a nice book, but don't get too excited about it. Most of the info given there you can find out on your own through experience, or by just searching the web (and the ogametips.com website itself!) As far as I can see, it contains absolutely no unique, groundbreaking play that no one was previously aware of. Still, it's a nice compilation of strategies and if you like having a single, almost-definitive source, then by all means, go get it.
