GTA, the very first one on Playstation, I must've been... ooh... 6 or 7 in 1999? Excellent parenting right there!
Although IMO, that game had nothing on the explicitness of III onwards. (All of which I've owned by the way and I'm still not 18 for another two weeks exactly!)
Also, Fun Fact: I'm not a complete fuck up either. I'm polite, I have awesome friends, I visit my Granny often, I study, I go to University and I'm currently looking for a new job so I'm not leeching off my parent's constantly. I've only gotten violent a few times in my life, but that was because the school, everyone there has had a fight at one point, even half the teachers.
