I don't know about EverQuest 2, but my wife plays World of Warcraft and her main reason for doing so is the social element of it---she likes going on raids with other people, teaming up with random people to complete quests, and helping her online friends level up their characters. In other words, she likes WoW for the exact reason you'd never, EVER see me involved in a Mumorpuger, namely that I'm your stereotypical introverted shut-in singleplayer gamer (well, not TOTALLY, but I've always viewed gaming as my personal, solitary pursuit, which is why most of my favorite games don't include any multiplayer at all.)
