The Rock-Paper-Scissors Game.
The generalized Rock-Paper-Scissors game (with a > 1) is a game where each player chooses between rock, paper and scissors as in the children's game. When a = 2, we have the same incentives as in the children's game, but when a > 2 the payoff of winning is relatively high compared to the payoff of tying and when a < 2 the payoff of winning is relatively low compared to the payoff of tying.
