Wishbone: I'm an admin in a Danish gaming community. We meet online every 6 days on our own server, and blow each other's brains out in various FPS games. We use TeamSpeak when we play. We have an average age around 30 years. Most of us are married with children. And we swear and curse at each other. A lot.
Of course, it helps that we're all friends, and that most of us know each other in real life one way or another. Also, it's probably a cultural thing. Danes are much less uptight about stuff like swearing. As it is, if one of my buddies is lining up a shot with an Ion Painter (UT2004), and I headshot him with a sniper rifle and steal his weapon, I'd be slightly disappointed if I wasn't immediately accused of performing sexual acts on goats in my spare time, or something equally offensive. Or alternatively, congratulated on an extremely well placed shot. It varies.
My point is, sometimes it's all part of the game. The more violent the game, the more likely it is. It's all in good fun, and we're all equally good friends nevertheless.
Still, there's a difference between being cursed at by a friend and being cursed at by a complete stranger, but more of a difference, I think, in how the curse is spoken. As long as I can tell that the other person is cursing in a "good-natured way", I don't mind a bit.
That you are all friends makes all the difference. It is a completely different thing to have some stranger cursing at you. As y'all have your own server, that wouldn't be a problem though.
