If you haven't, go a play Vincent's other games a couple of times each.
I strongly recommend playing the Rock of Tahamaat and GHOST/ECHO (otherkind dice). You might get some stuff out of Dogs, Puppies or IAWA, but I think Rock of Tahamaat and Otherkind are both important to playing AW well.
I just played it (RoT) for the first time last weekend and I've been playing Apocalypse World on and off for three years now. And I finally just deeply grokked Moves and the relationship between the MC and the PCs.
I think it's also, after playing some Monsterhearts and a bunch of Dungeon World, that while Dungeon World is extremely successful (and I say this with zero malice; Adam is a personal friend) DW shouldn't have been an AW hack. And suffers for it. It's a great game, though, and remains my D&D emulator of choice.
Also, after a year of contemplation, the problems I'd been having with Eschaton are starting to be solved. Being solved because for that year I played other games. Like, card games, board games, computer games, (I also studied games being made, but that's another weirder thing) etc.
Just an idea.
