I was a bit underwhelmed by this after all the other good reviews. There are some good bits in this book and the art is excellent. I'm most disappointed about the additional moves, particularly the hireling, movement rules and weather rules. They seem to add more complexity to the game without adding additional fun. A few of the moves seem to be text book examples how you shouldn't design moves, according to the Dungeon World rule book. For example giving players options to do nothing. The compendium classes lack the zing and weirdness of the ones provided alongside the original rules. The random dungeon creation is good and the descriptive text is well written. I think the problem for the authors is that Dungeon World is so subtly well designed that the most likely result of adding more to it is that you end up with something that isn't quite as good. I got the same feeling reading this book as looking at a Lotus Elise that's been fitted with aftermarket 'improvements'. There is good stuff here but I'll be using it sparingly in my own games.
