Does Gaming Kill?

There is a reason why games like GTA are Mature rated. Honestly, i say: throw a warning whenever you start up the game: "THIS IS A GAME, DON'T DO THIS IN REAL LIFE".
I don't mind these games, since i play them now and then too, but seriously, if people do stupid things because of those games, they should have known better, it's THEIR fault, not the company who made the game that 'inspired' them to do it.
