I personally adore this game. It's possibly the most flavorful, intense, and creative RPG book I've seen.
I did run and play in a short campaign, which unfortunately fell apart for reasons I believe are mostly to do with the group, not the game (it wasn't what the group was looking to play), but this review makes me excited to run another campaign with a different group of players.
I'm interested in a more in-depth how-to guide on running a game driven by player character Beliefs, Instincts, and Traits.
