Great comment. I think there is a too-literal approach in relating game worlds to the real world, when pretty much no one actually believes that. Instead, we realize at a very young age the differences between playing and real actions. Playing lets us explore feelings of power and powerlessness in a safe way, whether it's playing GTA, Cops & Robbers or Chutes & Ladders.
Even puppies understand play vs. reality because it is so fundamental. I don't know how anyone can buy the concept that mashing the A button on a controller is going to turn you into a murderer or reveal your truest self.
