ARS: The iPhone version of Final Fantasy Tactics is a port of a port, an enhanced remake of a game that was originally released more than a decade ago. It's a game that costs $16—roughly 16 times the price of most iOS games. It's old, expensive, and you can find it elsewhere for cheaper. Then again, it's also one of the best strategy RPGs of all time, playable on your phone. So maybe it's worth it.
