He added to Rock, Paper, Scissors and came up with RPS-15 (with 15 signs) and then RPS-25 (yep, 25 signs). Then he added on to those games and made something "so complex, I highly doubt anyone will actually even want to attempt to play it." Dear lord, it's RPS-101. (Previously)

Game Theory at the movies. The Princess Bride demonstrates the use of common knowledge, Butch Cassidy laments pareto equilibrium, and Swingers is an example of pooling equilibrium. Though no longer on the site, you can still see the most involved rock, paper, scissors game ever filmed [.mov].

RPS-15 (and, if you can handle it, RPS-25) for when traditional "Rock, Paper, Scissors" is just not enough.

Roshambo: It's a religion, it's conflict resolution, it's a cult of personality, it's a way of life, it's rocks and paper and scissors grooving up their thing. Worship of Roshambo.
