There are a lot of great Fate games out there, but I still think this is the best one.
+ The setting of the Atomic Robo comics is incredibly fun, and the comic art used to illustrate the book is excellent.
+ The rules are explained in a tone that is conversational yet specific, and illustrated with comic panels to show how the game emulates its genre. IMHO this book is the best way for new players and GMs to come to grips with how fate works.
+ It also introduces new, valuable mechanics to the Fate toolbox. There are rules for superpowers, inventing new tech (which can also be used for rituals or long-term projects), and improvising solutions to mysteries. Additionally, many of these are tied to being good at science, so less action-oriented characters get to do lots of cool stuff!
- The only complaint I have is that so-called 'EZ character creation' is actually kind of confusing in practice, at least the first time! Still faster than most other RPGs.
