I've never actually played an MMORPG. I avoided EverQuest in University when everyone was playing it. I never got into WoW (I did have a friend who lost his virginity to a girl he met on WoW so...I guess it helps some people).

I feel religiously opposed to them now when I see how involved people get into those games. I'm all okay with Quake/CounterStrike/Left4Dead type games where you shoot-em-up with a team for a bit and then it's over. Those are good breaks when you've been on a project for hours.
