I really wanted to say Bluebeard’s Bride, Masks, Undying, and Firebrands as well, for various things they each do.
Also Jeremy Tidwell’s psychic maelstrom dustbowl game and Gary Montgomery’s gunners in trucks game are things I want to play right now.
I think John Harper’s World of Dungeons and the Big Bad Con metagame do some great stuff with the system as well.
