The dance parties are a mix of casual and meta talk about the game, role playing (and Erotic Role Playing),
So far this has ruined every single commercial roleplaying server I've played on and I ain't shittin you either.
I played Ultima Online on a very strict RP shard, with quite a lot of players.
Roleplaying mostly meant a believable world there. You had factions, political organisations, intrigue, organized crime, religious zealots, traders, markets, rivalries, a working feudal system, etc. etc.
And everything was played really nicely. It was the best MMORPG I have ever played.
Of course there was that kind of erotic RP too, but that was minor compared to all the other stuff.
And what do ya get on commercial roleplaying servers?
Fuckin goldshire
Second life styled furry gatherings
Draenei with horse shlongs
It makes every single RP shard look like a big community of (really far out) weirdos.
It's the worst.
I remember the best RP community after UO was the one in Warhammer Online.
And you know why? Cause orks don't have dicks, dwarfs have ugly women and while Chaos would lend itself well to tentacle porn Slaanesh is too kinky for even the biggest weirdos. The only ones that had "potential" there were probably dark elves. But the game was too unfinished in those parts. Probably for the better.
