I got all kinds of problems with Burning Wheel as a game, in spite of (and because of) it's the game that my 14-year-old self fantasised about: Detailed, realist, scholarly, actually playable.
So I say play some Apocalypse World. Or an unholy mashup. No reason you couldn't play straight Apocalypse World with fantasy colour. Watch Verhoeven's "Flesh and Blood" and go nuts. Incorporating Apocalypse World's setting assumtions into a different context is hell of provocative, I think you'll find.
The only one of these games I've run before is DitV (Technically I've run BW before, but not really _successfully_).. I'm tempted to try running AW anyway. Is this a horrible idea? (If you were playing in my game, would you feel cheated or something??)
If I did run AW, I'd like to just do a normal first session. Is it necessary to do something more 'prepped'? (I mean, I'd prep some ideas of what to do in case things get 'stuck' I'm asking if I need pre made characters/scenarios/love letters)
Any advice for people who have never run a game at a con before?
What I like to do with AW at cons is play an abbreviated normal first session in the first half of the slot, then break for 10 minutes, then play an abbreviated second session in the second half of the slot. Including end-of-session and beginning-of-session stuff for sure.
Before you play, choose which playbooks you'll put on the table. My choice is hardholder - and insist that someone play it - plus brainer chopper gunlugger savvyhead and skinner, plus whichever LE playbooks seem fun that morning. You'll have to figure out your own favorite selection, but I do recommend only one of hardholder, hocus and operator, and insist that someone play it.
I'd probably specify the number of players you want, just in your game's description.
