I always get carded every time I buy an M rated game at TRU. I'm 16, so I have to get a parent to come up to the register. This never happens when I buy games at Gamestop, EB, or anywhere else (except Wal-Mart).
Just the other night, when I was buying a few clearance games at TRU, 3 of them were rated M. The cashier asked me for ID, and I told her I didn't have any. She asked how old I was, and I said 16 (yeah, I should have said I was older). So she asks another employee how old you have to be to buy M rated games. He says 17, but he told her to just give them to me because they were closing in 5 minutes. The lady refused, and said I needed a parent. So I had to go get my mom who was sitting in the car outside, and get her to buy me the games.
