I've played a lot of different MMOs. The first one that could be considered massive I suppose was a game called Air Warrior. A friend down the street has me playing Star Trek Online while waiting for Bioware's TOR to be released. I have plenty of friends and am a regular at a karaoke bar (AND I actually sing there, sometimes very badly, sometimes pretty damn well).
and, AND

It has only been 3 days since I had sex... WITH A REAL LIVE GIRL *crowd gasps*. That's a repeatable quest that resets in 3 hours. I can say your quote definitely does not apply to "all".

People play MMOs for lots of different reasons.
