First, see here: (PSN - Final Fantasy Tactics) ...and here: (PSN - Final Fantasy Tactics - War of the Lions)
I don't have a Sony system, but I do own an iPhone. From the App Store, I have downloaded and I am currently playing FFT-WotL. From what I can tell it's the same as the original, with a few tweaks for it to work on a touch-based device.
There aren't two versions within the Apple App Store. I'm curious, what are the differences between the two PSN versions?
Can someone clarify?
