Final Fantasy Artniks gets updates with quests to defeat infamous enemies like Kefka from Final Fantasy VI and more recently Sephiroth from Final Fantasy VII.
Square Enix announced today Final Fantasy Artniks reached one million registered users. The game launched on November 30, so it took a little over a month.
