I'm gonna run another AW at a con. Last time, we just winged it - with my humble suggestion of a post-apocalypse Seattle as the setting (an homage to the first game I MC'd).
I've heard of hits and misses from pre-game preparation, yet I want to try it for myself. My idea for a variation on love letters or starting Hx was to ask the PC's what they've been dreaming about, and assign Hx on that in lieu of the normal questions.
For example,
"Name one PC you've been dreaming of every night."
"There's a PC who keeps dying in your dreams, and you're never able to save them. Who are they?"
"You dreamed that one PC was trying to tell you something important, but you woke up before they could say what."
If anyone is interested, I thought of making a "sweet dreams" list for most PC roles (Brainer, Savvyhead, Gunlugger/violent bastard). I'm open to feedback, suggestions, apocalyptica-filled dreams you've had lately, etc.
