Yes, of course. But the OP basically wanted to gamify teaching rationality, in particular by providing immediate feedback to decisions in a game setting. What I am saying is that modifying an FPS game so that specific rationality challenges (which reflect what you want to teach) result in gaining or losing power-ups is much easier than setting up a many-people physical game.
