The thing to remeber about MMORPGs is in the end, the people are what matter. The game can be crappy, but hey, you don't think of that much when you're racing around a made up racetrack with some friends.
I used to play Star Wars Galaxies, not the best MMORPG, and the only MMORPG i've played, the best thing about it was the community. Well, the non-morons/jerks. The game itself was nothing particularly amazing.
I remeber with one character, who was a "Bothan", everywhere i'd go i'd get pet because the race had a vague resemblance to dogs. Was funny.
Its' the people you end up missing when you finally quit the game. Not the game itself.
