Sepharo, you make sense.
Sam, you're completely wrong.
The average age of a FPS violent game is 13-35, and mostly made up in the 16-24 bracket.
If I had a 15yr old son that wanted GTA: anything, I'd tell him that at 16, I would begin to look at his maturity level vs. adult material. At 16, I'd talk to him about porn, sex, drugs, alcohol, games, movies, and whatever else he wanted to talk about at a more even eye-level. I'd still be his dad, but I'd begin to be less parental & more advising friend.
At 18, even more so. At 21, all bets are off. So from 22 onward, he would hear man to man advice.
But you know, all that means nothing. At 16, I was old enough to make my own money & buy my own shit. I don't need mommy or daddy, and your gamespot ass isn't gonna stop me from buying anything in that store.
Bad parents & Bad kids is the EXACT REASON that we need a good law to enforce ratings.
And bull, fucking, shit about all the money it would take, blah blah blah. It doesn't cost hundreds of millions of anything. All you do is fine everyone the same way we do with minors purchasing alcohol. Those fines are heavy. How would you like to have a 7-11 paycheck & have to pay a $800 fine because you sold a beer to a 20 year old. YOU CHECK ID & if you didn't before, YOU DO NOW!
