It seems it doesn't. But it's a fail-safe against morons, so that they don't raise up more morons. Now, if I were a parent, I wouldn't feel that too much of my liberty would be taken away by a game that would be rated "mature audiences only".
Sure, my kids could disagree, but it would be up to the authorities to prove that I would be taking away from their personal freedom by prohibiting my kid to play games I'd feel were inapropriate for him/her.
And with moronic parents who don't care, or who lack the imagination, someone has to make the effort for them. Naive, innit, no?
I'm all for a good age restriction for
buying games! Kids shouldn't be allowed to just go to a store and buy a military simulation, liquor or porn.
However they should be allowed to own it, for example if a parent bought it and gave it to them. If they think it's appropriate it should be their decision.
For example I could think that "Fable" is appropriate for a 12 year-old because the reason for it's higher rating are the so-called sex scenes and the possibility to marry male NPCs. Neither of which is a problem for me so I decide to give it to my son. No one should be allowed to take that decision for me.
It should not be the governments decision, nor should it be the shop's decision, though unfortunately the latter is the bigger problem at the moment - and the one that is harder to solve too.
Some stores refuse to sell AO rated games AT ALL - not just to minors! - because they fear the angry mob of over-opinionated moms.
This means that while there is no real enforced censorship there is a lot of self-inflicted censorship for the sake of a commercial success.
So the reason for censorship isn't as dark as that of an intrusive government censoring our movies/games but the end-result is pretty much the same.
I don't care whether Spielberg covered up the guns of the FBI agents in E.T. with Walkie-Talkies to get a lower rating or if the government did it for him. The result for me is a ridiculous scene in a movie.
Well, bad example because E.T. was never endangered with getting an AO rating, but you should get my drift.
censorship = censorship
Be it an economic censorship or a political one.
The main problem in this case and in many others is that people are way too up-tight. If that would change we wouldn't have discussions like these and frankly I'd be tempted to say that there wouldn't be as many shoot-outs either!
