OT: MMORPGs & other Online entertainment

[AgentZero]

I've recently began thinking of giving Online gaming another try. My Last forray started with a visit to a Quake-Con like convention, and the sheer egos of those involved put me off the experience the Last few years. And of course we've all heard the horror stories of the behaviour of some of those involved in Online gaming.
I was wondering, since you lot seem like such a decent bunch, do many of you play any Online games, aside from SE PBW, anyway? I've been thinking that World of Warcraft looks a little too tempting to resist, even though I'll have to wait a few months for the European release.

Also, my broadband provider slaps me with monthly download/upload limit (which I personally think defeats the purpose of broadband), and I'm wondering just how much information is sent back and forth when you're playing something like WoW, EQ or the like. Obviously if it's something significant, that might put a hold on my plans for a while.
