What is the best MMORPG voted

Well I've heard that runescape set a world record of "The most played MMORPG" and then there's Maplestory but TRUST ME you do NOT want to play that that place is full of pervs, hackers, and harrasers but then again its so cute! But for me i play ghost online, kinda like maple BUT it was made BEFORE maplestory so maplestory is kind of a copied version of ghost online.
