well it add some realism to the game... I mean that's true that too many games you empty a clip on a guy and he is still running at you and if you stop shooting him he'll be running at you for ever.... it's like sports game.... why is it interesting to have fans in the stands ?? it doesn't change anything to the gameplay... it just participate to general atmosphere of the game and you feel more into it...
and over all FPS are violent... so it's the spirit of the game... how many people were getting off on the chainsaw in GOW.... it's just freaking awesome to slash your friends on a game and make fun of them for half an hour after that... i
