I'll probably be shot down hard for this but.....
Ok I've never played GTA but one Christmas a few years ago a younger cousin got it and was playing while all the kids watched. I watched about 5 minutes and in that time a hooker was dragged out of a car, punched several times and then shot in the face with a shotgun (Is my memory correct or exaggerating?).
There were kids ranging from 4 to 18 watching and I decided to put my breakfast beer down and asked them to turn it off.
Now I grew up on horror movies in the 80's so I don't mind a little Scanners head exploding but now that I'm a teacher I see and hear about kids in my class (primary school) watching movies like Hostel and Mamma and Insidious.
When I was kid and there was a fight at school we all gathered and watched including me so I'm not preaching but kids these days start fights so their friends can record it and during the fight chant 'stomp on his head'.
Earlier this week a boy in my class asked my why it's so easy to push girls around and when asked he thought it was ok to punch a girl in the face if she hits him first. I grew up being told 'under no circumstances do you hit a girl/lady'.
I know if kids are raised properly you don't get these issues but so many parents are failing and having access to images/games/movies like the one above isn't helping and I don't see why we need games where people are being killed so realistically.
Ok rant over and now I feel really old
