I saw a lot of people were turned off by the "in game" parts. As both a tabletop role player and a video gamer, I can say that I "got" just about everything the author was talking about. That being said, I can understand how someone who has never been a serious MMO or tabletop gamer might not like these parts and indeed even I could have done without them. But over all I really liked this book. Maybe not for everyone, but it'll stay on my bookshelf.
