Whats your favorite mmorpg

Just a couple things that has to be taken into account before you answer.

It has to be completely free. GW has a cover price so it doesn't count. It can have payment options for special items and whatnot but the majority of the game can be played for free. Like in Maple story you can buy outfits but its not necessary.

A game that's still updated frequently enough.

Runescape doesn't count

I'm looking for a new mmo right now to play since I kinda quit GW. Three years is a bit much for one game lol.
