In all honesty, I don't know why. I guess parents don't care if their kids are exposed to violence. But, like I said before, show a nipble, ass, whatever, parents will get stupid and start complaining and whatnot. Rated M games are rated M for a reason, because the game has content that isn't suitable for younger audiences. However, these half-assed parents will still buy the game for their 10 year old. Society is messed up now a days.
So I guess most of you are teenagers, and don't have kids? Let's check this out from a parent's view:
-WE just don't ahve time to keep up with all the games being released. We tend to rely on RATINGS to make decisions about what games we want to let our kids play.
-Most kids are better able to handle violence than sixual situations. It's a lot easier to come away with a skewed sense of sixual relationships from media, including games, then it is having problems determining the ramifications of real violence vs fake violence. Showing early teens that females can (should?) be used as objects will likely affect kids more tahn blowing off heads will.
-There is substantial evidence, form all over the world, that six and violence portrayed in media, including games, does tend to affect a child's world view.
Of course, many parents just don't care, and use these games to just get their kids to shut up. Problem is, parents are not required to take parenting classes, or to otherwise qualify as parents before they ahve kids.
But most of you will find out first hand, and then you will ahve to deal with trying to raise kids.
Good luck.
