I am 32, I have played so called "Violent" video games my entire life, growing up with GTA, Battlefield, CoD and more. I even own firearms and I have never once ever wanted to harm another human. In fact in games like Mass Effect with a paragon system I have never been able to play the game as a renegade and will always give up trying to be a dick in any game that gives me the option if the writing is compelling enough to make me feel like crap if I do so.
