The races are imaginative, the classes are well thought out (operative might be just a bit better than the others though), and incredibly smart streamlining to the venerable 3.5 mechanics the game is still recognizably built upon.
The setting is compelling too. Too bad there's no mini bestiary. It's the only thing that's missing.
Automatic Bonus Progression is enough to justify the entire price of the book. Better versions of the Rogue and Monk, as well as fixes to the summoner and streamlining the barabarian seal the deal. There is a lot of other good stuff in here as well. Well worth it!
