With almost every RPG thing I read, I'm left thinking, "I wish this was 10-30% shorter." Traysikel is maybe the first time I've thought, "I wish this was twice as long."
If you're reading it for the first time, read the player pamphlet first! Even if you're going to GM it. A lot of the open story information is essential in understanding things in the GM pamphlet. Definitely not a slight against the game; I'm just a forever GM, so I always look at GM sections first.
Five stars! Gimme more.
