Fiasco!

Fiasco is an award-winning, GM-less collaborative storytelling game where 3-5 players create and play out the story of ordinary people with powerful ambitions and poor impulse control, resulting in disastrous, darkly comedic situations similar to a Coen Brothers movie.

The game, playable in a few hours with six-sided dice and no preparation, uses dice to establish relationships, needs, and locations in the first act, which then unravel in the second act after a "tilt" introduces unexpected chaos, leading to a final aftermath that reveals the consequences of the characters' choices.
