Star Wars Game Theory
In the original Star Wars movie (Episode IV), Luke Skywalker pleads with Han Solo to help the Rebel Alliance battle the Empire, but Han refuses and a disgusted Luke storms off. Chewbacca, being a student of game theory, lays out the payoff bimatrix to Han in their “conversation”:
Han understands that the Rebels have a dominant strategy of fighting. Knowing that, although he has no dominant strategy, and being the self-centered person he has already shown himself to be, Han realizes he is better off choosing to aid the Rebels and fight. (Fight, Fight) is a Nash equilibrium and also a Pareto optimum. I wonder how many other Star Wars games there are.
