I would never have predicted I'd be playing the Ungame with one of my inlaw families over Christmas break. But that, plus a viewing of Fargo, leads to this.
Get a Fiasco ruleset. Assign characters, relationships, etc.
Then, instead of playing Fiasco, play a game within a game. Your lowlife Fiasco characters are trapped in a community rehab house, playing an hour's worth of the Ungame . Answer the questions from their point of view. The challenge is to tell a story through the playing of the game. Good luck!
