(In reference to THIS and THIS.)
Grand Theft Auto: San Andreas is now rated "Adults Only", for the reasons I mentioned earlier. I will repeat that I don't see how anybody in their right mind can make sense of this. I guess it's just a case of blindly following outdated rules: "violence = mature, sex = adults only".
Additionally, there are things in the game that mix sex and violence. You can get a hooker into your car, boink her, then run her over (or shoot her, or beat her to death with your bare hands), and get your money back. But because you don't see her boobies (you just see the car shake from the outside), that's just fine for kids. The moment you see a nipple during consensual sex between adults, though? That will corrupt kids for life.
HERE is a nice link to a commentary on this issue, wrapped within a story. Funny stuff. Read it.
