There is also a neat boardgame called Fog of Love, where you play through a series of interactions in a relationship. You are basically iteratively playing the prisoners dilemma, but the payoff matrices are asymetrical, and so to have a successful relationship, you need to become adept at reading the wants and desires of the other person and modifying your behavior accordingly (or not). If you are packing to go to a wedding, do you pack early, last minute, or just buy stuff once you get there? If your partner is a rich slacker thief and you are a hyper organized security guard (real situation from game), do you compromise, or have a fight?
