Wow. To the ~90% of retards saying yes to this. I'll just assume you currently play, or have never played an MMO (the posts supporting it prove my point). Because anyone that has experienced end game MMO play, and has quit... knows what's up. MMO's are a mindless drain requiring nothing from the person but time. The disgusting constructed interest in these games from said MMO player only further highlights their utter lack of thought and gaming ability(if skill turns you on, that is). The obvious example is WoW, but any MMO fits the bill more or less.
QQ about my bias vs MMO's all you like. But I know better (I've had GF's in my MMO, and GF's who couldn't play anything past tetris), someday you may too. It seems cool having a GF that plays the same game as you, where you can sit together and watch your characters run for 6 hours , but...
Wait I just remembered. Anyone playing any MMO is so convinced that it's worthwhile that they will never understand a word I'm saying until they quit.
Dangit.
My opinion is clear, playing an MMO is a red alert to a person not respecting their lifespan.

For the same reason I'd not date a crack-whore, I would not date an MMO player.
