Firstly because, just like the movies, it's a pathetic excuse for fame. Secondly, it's net exactly the type of thing that the ratings people will be to happy with. If they don't like GTA, why would they like something about inflicting injuries onto yourself? Just asking for trouble if you ask me.
Not sure if you messed up that sentence or not...because I was a little confused when I read it. But just because something is a pathetic excuse for fame...doesn't mean it'll be banned. I consider rap a pathetic excuse for fame...but you don't see that getting banned...just bleeped out and shit.
Typo, sorry about that.
About rap, well what do you call 50 cents video game? It was banned in Australia, New Zealand and somewhere else (forget where).
