those games are not so violent. they just go violent when the player wanted to win and let the other lose the game. the hurts are normal in all games like football, cricket but they are not  banning it because of their craze followed by the youth and the people. so they are not to be banned in this same way they wont be banning the games like boxing, kick boxing and wrestling.

hope so my answer is useful.....................^_^  !!!!
