Yeah, comparing GTA and Gears of War is like comparing Die Hard with Boogie Nights.
But, they also say forget and stuff and all that, so no, its like comparing, wait why the forget are we comparing games.
I think it should be allowed, if you really don't want your kid playing rated A games, you shouldn't be as stupid as forget to let them get their hands on it. Also whats harder, going into a back game room and going buy a rated A game with adults and people around, or google searching research?
