Juggernaut, from Bully Pulpit Games, is a live-action RPG that’s supposed to have players exploring the meaning of free will. Set in cold-war 1950, the game posits the invention of a computer that predicts the future.
Players draw a series of cards that represent computer output. Then because the Juggernaut computer is infallible, the players must come up with stories for how the predictions come true.
One session lasts through a deck of 22 Job Summary Cards but the game comes with a total of 58 such cards for a different experience each time.
