I can relate to a degree. But not if you use the movie rating system as a template. Kill Bill is far more violent, and has far more emotional impact than GTA. The sex in any number of R-rated movies, Monster's Ball for example, is a hundred times more graphic (and sexy for that matter) than anything found in GTA.
But I don't so much think of the ratings system as broken so much as our society. The ratings system is just a reflection of our society and it's mixed up priorities. We really just don't care so much about violence. The amount of graphic violence you can see just by flipping on an episode of Law and Order: SVU on primetime network TV is astounding. I've always found it mind-boggling that using the "f-word" twice in a movie will get you an automatic R-rating, but in lord of the rings you can depict hundreds of severed human heads being catapulted over the walls and watch an orc walk up to a dying human and savagely finish him off with a spear in the gut and so on, yet still squeak by with a PG-13. I think I might have already mentioned the LotR example, but it's indicative of our tolerance for a great deal of violence.
Think of just about any R-rated violent movie you can, in fact, and I'd bet money that there is some other element in the movie, be it language or sexual content, that by itself would have garnered the R-rating.
I think it's kind of interesting that you throw prostitutes in a game like GTA and it makes enormous headlines, like that's some kind of serious problem we are facing as a society. We're one of the most, if not THE most, violent industrialized nation in the world, yet what we seem most worried about is that a videogame would encourage our kids to have sex.
The Hot Coffee scenes are the most graphic sex scenes in a mainstream videogame to date, but they don't even begin to go beyond, or even approach the sex scenes allowable in R-rated fare like Boogie Nights or the softcore porn you can get at the video store or watch on late-night Cinemax.
If GTA-Vice City gets an AO rating -- the most severe ESRB rating out there -- what are you going to give an actual hardore pornographic game? M seems to me like the appropriate rating for the game.
