i myself stopped playing wow because i just dont like mmo's in general. having said that, wow still managed to get me hooked for almost 8 years(played since release) and this is a feat that no other mmo can deliver. i tried other mmo's, i seriously did - but none of em have lasted me for more than 2 months.
wow - the best MMO up to this date, and continuing until infinity.
a little rant to the haterbase: to those "what if" -sayers , dont you guys know that "what if" works both ways? geez ~~ "what if wow never drops lower than 9 million subs?" - there! i said it, you read it. now gtf out and come back when wow has actually fallen to 3million! right now its you vs 9.6 million people out there, whos gonna win, huh?
