Well, to some extent threads like this can represent a division between what a mature (older) gamer and a younger one are like, and why a lot of kids shouldn't play "M" rated games.
Not picking on anyone in paticular, but I think that seperating fantasy from reality goes beyond sex and violence. Part of being ready for an "M" rated game isn't just the content (which in of itself might be bloody immature when you get down to it) but understanding that even the good guys/protaganists are not typically role models of any kind.
Yes, I know many people are joking, but honestly I think the fact that some people might see the qualities of say a Kratos, or the code of "ethics" exhibited by video game criminals, or vengeance seeking anti-heroes as fitting of emulation or in any way based in reality or how to deal with situations in the real world (even allowing for a lack special powers or whatever) is part of the problem.
Just a rambling thought.
I'm Mr. Anti-Censorship and believe than when it comes to mature games there should be no limits on the level of sex and violence they can throw out there, but there are some games that just aren't suitable for children, and that isn't just a matter of the sex and violence.
I'm throwing it out there again because for some reason I've spent more time than usual thinking about it. Mostly thinking about how to cut down on censorship by explaining how to properly define what requires a mature mindset rather than the sex and violence and such.
