Square-Enix has announced that Final Fantasy Tactics will hit the App store on September 15.
Square-Enix has had a shakey history with Final Fantasy spin-offs, but thankfully Tactics is one of the better ones.
The iPhone and iPod Touch release of the game will be a version of the PSP re-release Final Fantasy Tactics: War of the Lions.
Square-Enix seems to be quite taken with the iPhone, as it's previously released Final Fantasy 1 and 2, Crystal Defenders and an original RPG called Chaos Rings.
