It's a social game.
From the FFWiki:
"Square Enix has announced a new social game titled Final Fantasy Tactics S. The details are light thus far, but the game will cast the player as a clan master commanding different jobs to restore luster to the Crystal. A teaser site for the game depicts familiar jobs and monsters based on Final Fantasy Tactics sprites, such as Flan, Behemoth, Demon Wall, and jobs including Black Mage, Elementalist, and Dragoon. Viera, Moogles and Seeq are included among the sprites."http://www.jp.square-enix.com/ffts/
So, yeah. Make of that what you will.
