I'm not LDS but if you despise swearing how do you play FPS games online? Do you mute everyone? Because a lot of people have mics and basically all they do is cuss, talk about smoking weed, or make racist remarks.
I think it comes down to your own conscience, how important gaming is to you (is it part of how you socialize for example), and if there are other just as good alternatives to spend your time on. Good luck.
