Playing Games With Vulgar Language
You should be asking you own self that if you have other decent games and other entertainment readily available, then why should you indulge in things that you yourself know to be wrong? Constant or long term exposure to such things makes us insensitive about them. I would recommend that you find other games to play. If you must play the same game, then as you suggested, you can mute the volume or switch to a different language. I would like to add that in general, before we seek religious opinions about such matters, we already know the right and wrong from common sense.
