In everyday interaction, we spend a large part of our time either trying to fill a role other people expect or want us to fill, or avoiding that role. But a game removes this type-casting stress by telling us exactly what our role is. It gives us an arbitrary alter-ego into which we can escape for an hour and a half. We’re not John or Jane Doe trying to balance career-family-mortgage, we’re Colonel Mustard in the drawing room with a revolver. And we can act accordingly–which means, paradoxically, that we can act more like ourselves.
