I am trying out WOW and so far its ok. The graphics add a nice touch but arent a big deal. But what is a big deal is two things: Quests: Wow has alot of quests and they are interesting to do. UO has alot of quests, mainly for newbies. At the top end there is either 1 or 2 or no quests for high ranking players. But to me the biggest advantage WOW has is they sell game time cards at retail locations. I seem to remember UO doing that, but it appears they stopped for some reason. I for one would rather use a game time card VS a credit/debit card. A game time card is nice for those that don't have or don't want to use their CC online.
