So I was thinking about Monte Cook's Ork & Pie
scenario on the walk to work today. I mean, sure it's a joke, but it's a complete dungeon that fits on a single business card. That's pretty cool.
Why don't we have something like that for story games? Tightly packed little balls of situation, characters all pointing at one another, resolvable in under 20 minutes, with simple conflict resolution rules and a defined end. Maybe fits on a little double-folded business card printed on two sides.
Hand 'em out as designer calling cards and to promote larger games.
