oh **** off my son is one of the best behaved in his class , all of the teachers he has had have adored him.Allowing a 5 year old to play GTA is a fail anyway you look at it.
I have 2 boys (8 & 4). The 4 year old goes on Cbeebies only (very very rarely as he's 4 so is too busy being a ninja or fireman sam).
My 8 year old has a laptop with a 8600GT and an Xbox 360. Up until last week when he had a blast on BC2 the worse game id let him near is Unreal Tournament.
Kids are very impressionable at this age and allowing a child to run riot in a realistic city environment beating, killing and stealing with no consequence for his actions is setting a very scary standard for social responsibility. Yes we know those things are wrong but at 5 your a blank canvas.
Buy him a football!
kids dont think of games like you do, to him its just a game its make believe hes not stealing peoples cars hes "borrows" them, he doesnt run around killing people for fun he just drives around exploring the city.
to him its no different than playing http://www.roblox.com/
at five years old he knows what is write and wrong he understands the difference between a game and reality , he understands in real life there are consequences.
we arent destroying his tiny little mind by letting him play games you dont find apropriate.
