I have enjoyed WoW. The graphics are pretty (albeit a little dated), the action is fast-paced with little to no downtime (at least up to level 9, which is what I currently am), the quests are entertaining and plentiful, the world is varied and interesting, and the sound and music are typical Blizzard faire (i.e., top-notch). It has a lot going for it, but EQ2 still looks like the next big thing in MMORPGs.
