I've been playing fantasy RPG games since a friend of mine let me play Chrono Trigger on his SNES. Somehow I never had a desire to buckle up my sword belt and lay waste to my high school, despite the fact that the only person lower on the social totem pole than me was the girl with severe epilepsy. I don't think what people play or are exposed to has any bearing on what they're likely to do; maybe just on how they're likely to do it.
