Why oh why must intelligent commenters on here persist in making and spreading generic assumptions on the mental capacity of CoD/FIFA/Madden gamers? It would be no different to someone calling all players of Skyrim basement-dwelling, WoW-playing geeks or GTAIV players latent psychopaths just waiting for the chance to go murder happy.
