It just struck me that a killer payoff for a course on game design would be to have the students design the exam and evaluation themselves as part of the course. What would be good meta constraints? Clearly it's socially undesirable for the entire class to live inside a zero sum evaluation game (note: This is actually the case though in e.g. the danish grade system. Schools are called upon to reach an equilibrium across all students) - but clearly you still need some kind of constraint that actually makes it hard to win.
