Ultimatum Game

One AI character (the Proposer) is given money and offers to split it with a second AI character (the Responder), who can accept or reject. Rejecting means both get nothing — so any split is "rational" to accept, but real people (and, here, AI characters) often reject low offers out of a sense of fairness.
