Eliezer, I agree that your example makes more clear the point you are trying to make clear, but in an intro to game theory course I’d still start with the standard prisoner’s dilemma example first, and only get to your example if I had time to make the finer point clearer. For intro classes for typical students the first priority is to be understood at all in any way, and that requires examples as simple clear and vivid as possible.
