As I recall, I had to buy the video games for my son that were rated mature until he turned 18. I don't know if it was a Best Buy policy or if it was dictated from the government or industry association group. I thought the rule was good because I would look over the games rated mature to see the subject matter and decide if I thought it was ok. I never blocked buying a mature game. The rule just gets parents involved in what their kids are playing.
