Considering there was an entry that won an art competition that was a man pissing blood into a urinal to make it look like iron man.... We don't need to worry about games setting back the medium, the medium is fine and will be fine. The thing is, this is our medium, older people that have not grown up with it, won't understand, and are fighting against it. Video Games are ruining our childrens lives, making us all violent homophobic stupid monsters that hate women and want to shoot up a bank full of innocent people if what they say is to be believed. It's kinda like what TV went through. Video Games are just getting themselves settled in like every other media has before it and there will be tons of people bitching about it. In 40 years, no one will give a shit and games will be commonplace, we just have to get through the growing pains and listen to politicians and TV show hosts screaming about games being the cause of every atrocity happening in today's world. Hell, according to Fox News, after playing a video game for an hour I should have turned into a mindless slobbering rapist, yet I think I'm doing just fine.
You don't want the game, then don't buy it, but it's not going to destroy the medium or set it back. It might be crude, but that's how some art is.
