Actually you are wrong, the reason this "hamrless" mini game was taken out in the first place was because it took them from an M rating to an X rating and they couldn't make a boat load of money unless they got into WalMart - which only accepts M. So being the ratbastards they are, they decided to screw the most powerful retail company in the world by getting in their store and still selling X rated crap.
I don't have a 13 year old, I was making a point, but if this company can screw parents like this what is stop the pokeman game manufactures from adding hidden M stuff into their games? You can't tell me my fictional 13 year old wouldn't love that!
My point is still valid - ratings are there to help parents make decisions, and if the companies do shit like this to get around those ratings, then they are taking choice away from parents. And they are hurting the entire industry because parents will stop trusting games, and criminy, send thier kids to Football camp (yuck!)
