I'm working at Toys R Us again and in the briefing they were telling me that you can't sell a MA rated game to anyone under 25! Can you believe that?!! A video game?!
You can legally buy alcohol and buy cigarrettes and even buy fire arms before the age of 25, but you can't buy a video game. Now as to how effectively this will be followed, that's another story. I don't see it happening.
