Actually I could be used as an example! (12 year old boy here) well I play fantasy violence like final fantasy etc but not shotting games like F.E.A.R does games scare the hell out of me!!
Anyway if I see a cool move in a game or movie I would have the urge to use it on somebody but I don't! and if I actually play a shotting game I wouldn't feel like killing or hurting somebody. So there it might and it might not and I'm not really violent! *mugs little kid* umm...that proves nothing!
