Favorite Online RPG

What is your favorite MMORPG? And why?

Me: Final Fantasy XI - very indepth, feels like it has it's own world. When you do something you get a feeling of accomplishment.

ITT PROOF THAT WOWFAGS AREN'T THE CANCER THAT'S KILLING 4CHAN. NOTHING MUCH HAS CHANGED AFTER 3 FUCKING YEARS
