I don't mind swearing in Video Games whatsoever. I do mind, however, the people that complain about swearing in Video Games. That's we have a rating system called the ESRB (PEGI if you're in Europe) to warn potential consumers about the content of said game.
In fact, I find that in certain games, profanity brings out the emotion in characters during gameplay. Having a dumbed-down version of a game without profanity is just basically a game with a storyline and a bit of interstitial speech, and nothing really special.
