It happened yesterday, and it went splendidly, largely due to the excellent advice and preparation I received from kind Apocalypse World players on the Internet. Thank you!
It was also crucial that I had the chance to run it a week before. That game also went well, so well that it is becoming an ongoing game. We'll be playing again this Thursday.
I was amazed at how well asking lots of questions works with enthusiastic role players. I presented each player with a few questions about the world and their place in it, gave them "love letters" with moves to kick start the action... and it all just snowballed.
I did not consult the moves list often.I studied it in advance, though, and it helped me think of interesting failure results.
Directly addressing characters has a power greater than anticipated. I had always tried to do that, but I used tent cards to ensure I addressed the character every time, and it really enhanced engagement.
It was everything I hoped for. Thanks for all the assistance!
