At what age did you play your first M rated game?

[PenguinZ]

12, with GTA III. I remember seeing it in the bargain bin at Walmart honestly not know what it was.... My mom bought it for me... little did she know. I got Vice City a month later, and San Andreas released later that year. I got San Andreas day 1, but my parents knew how bad GTA was by that time... However they figured I had a good head on my shoulders and that I could tell the difference between right and wrong.
