Don't buy WoW... i played it for a few months, its all fine and dandy - there are tons of people playing which is good, but the game just lacks that little something to keep you hooked after the awe factor is gone. i have a friend whom has been max lvl for quite some time, and only logs in to wonder around because he has nothing else to do, he is just waiting for the expansion so there is more for him...
I strongly stand against WoW.
