Well I didn't actually own an "M" rated game (which is 17+ here in the States) till I was about 15 or 16 (I can't really remember). But I do remember playing Halo and one of the Mortal Kombats back when I was 7 or 8. I didn't really play a lot of M rated games from that point on either. I remember playing some Diablo at a friends and I bet I played some others, but my parents didn't want me playing anything too mature for my age so I didn't even play a lot of T rated games until I was in my teens. They were the same way about movies as well. Still are.
