I really like this answer:
I think the moves are those things where you say, "Hey this is what I want to do." If you want to boss around a gang and put down mutiny, take a character with Pack Alpha. If you want to take on groups of people and shoot them up, take a character with Not to Be Fucked With. If you want to be the one who gives advice, take Oftener Right.
I think Moves are the next step for trad game skills and abilities like you find in Shadowrun or GURPS, and transmute them into something in line with what Luke is describing.
and this one:
AW is all about letting the players direct. The MC's job and the MC mechanics are all about making flags unnecessary: why use semaphores when you've got a cell phone?
In my original post I wasn't assuming that Apocalypse World needed some written or mechanical player priorities that it doesn't have; I just wanted to hash out what player priorities look like in AW, because I sure as shit can see that there's no lack of player-driven activity in the game.
In that regard these thoughts from Bret and eggdropsoap (dude, what is your name?) are great, and get me to this point in my thinking: any move the character makes is a player priority in Apocalypse World, because the game is all about them. Because there's no plot.*
Bonus realization: I asked a long time ago why the MC is called the MC, and I never got an answer, but after MCing and thinking about it and reading this thread, I get it. It's just a flag to get you, MC, to understand that it's not
your game, it's
our game, and you're just the Master of Ceremonies and accordingly should have the attitude and role of any MC at any gathering: Facilitate, smooth over rough spots, and contribute to this party while letting others contribute.
*btw, I haven't played a lot of Burning Wheel, but to me in that game the GM doesn't bring a plot that's suited to the player's Beliefs, but rather puts obstacles/interesting things in the way of those Beliefs, and what the players do and what GM does creates a story. Much like in AW. In this regard I disagree with eggdrop's earlier post. But this is a tangent!
