What do ypu think about boys and girls as young as 9 saying their favourite computer game is Grand Theft Auto which is a game where you steal cars,run from the police,get arrested,watch people take drugs and meet prostitutes
This sort of suggests a pointlessness in have the age ratings if parents are going to ignor them. you can say all you want about shops selling games to underage kids, but in the end a child is their parents responsibility
Definitely a no no. they have an age rating for a reason. It's all pretend but watching that level of violence when a child is so young can't be doing anything positive for the child.
I think if you make sure the child knows its just a game and things like that shouldnt be done in real life is ok but depends on the child and the parent/s
