Thanks! From the same game:

Only one i've played is Guild Wars 2.

Back in the day I tried a lot of MMO's: Ultima Online, Everquest, A Tale in the Desert, City of Heroes, etc... I even did the free trial to WoW. By far the best one was Final Fantasy XI. They actually put a lot into the characters, monsters, areas, and other stuff to make you feel like you are in a rich fantasy world. The game mechanics were originally awesome too, but they changed the game play a lot to make it more like WoW. I haven't tried FFXIV, but I have heard that is the best game to go to at this point to get the quality of the original FFXI experience.

For me it's definitely Old School Runescape. That's really the only MMO that I ever really sunk a lot of time into.

WoW through to Wrath of the Lich King.
