this is such an irrelevent topic since MS is a sidescroll game, WoW is a 3d game, and RS is a jave game. overall i think wow is the most preferred to play
mmm I hate WoW , but in this case i prefer it, because runescape is so ugly in graphic , maplestory don't have lvl cap and you can do super mega damage !! And BTW WoW is made from Blizzard!!
