Okay, so I figured we could start a thread to pick playbooks and share some ideas about our setting for this emergent game. In order to not just call it "Apocalypse World", I've added in one setting element already that I'd quite like to try - this setting is at the edge of the sea, a dank-grey, foul-smelling, tideless ocean from which strange noises emanate and occasional creatures emerge. I've given zero thought at all to how this will interact with the system, so I guess we'll play to find out.
Feel free to pick your playbooks and even post up characters here - I tend to err on the side of sharing everything here with everyone and trusting each other, but if you're desperate to keep secrets feel free to whisper me. Once we've started to pick playbooks I'll start an In-Game thread where we can add setting elements in a conch-holding round-robin fashion - nothing too definite, but enough to give ourselves something to play with.
