I've played two mmo's, swg and now this...why? because all the other midevil/fantasy stuff holds no interest to me. I think star wars has the most to offer for an mmo in terms of variety of different gameplay styles. It has everything to offer from space combat, magic, rocket launchers, bounty hunters, monsters, and on and on. Just the definition of star wars = no end game ever.
But no....if this wasn't star wars i would not play it....because all I ever have seen hyped about this game is heroic single player fully voiced stories. That is awesome for a single player/co-op game. Not for an MMO. Actually now that I think about it, I'm playing because I know a single player kotor won't be made again ever or if not ever for at least 7+ years...
