I've played a number of MMOs and only two have caught my interest for awhile.
Maple Story, and Granada Espada.
Why? They brought something different to the table.
Maple Story brought a 2D, (semi)fun, and cute MMORPG.
Granada Espada brought the "team" element. You get 3 characters, and you play all of them at once. The only downside is that people can just leave their characters in a spot, and the characters will kill automatically.
To me, those are the only games that aren't 'cookie cutters'.
I almost have given up on all P.C gaming...
Starcraft is getting old, Gunz is full of hackers, stopped playing SRO so much, got tired of Maple Story out of nowhere, Warrock sucked after beta, I played all of the FPSs (I could run), theres little RPGs, theres no fighting games, or atleast from what I know..Racing games pretty much suck with keyboard controls, which make you buy a steering wheel, a waste of money. Sports games definitely feel better on a console.
