How old should you be to play a mature rated game?

Does it really matter?if it does 17

You should be at least 11,12 or 13.It depends on how "bad" the game is.

11 years:Castlevania to maybe Halo

12 year olds should handle Team Fortress Games.

13:Anything that's not as bad as grand theft auto

~My Opinion

Well....it depends on how you look at the game. I think that people that are 12 or 13 should be mature enough to play games of the such. But of course. There are alot of immature KIDS out in this world, and they can't handle most stuff that happens. Soo...I guess games shouldn't have a rating but then I think they should. If that makes any sense what so ever....
