Square Enix just dropped Final Fantasy V on iOS and Android, recently announced Final Fantasy IV: The After Years (a sequel with an awful literal title released to phones in Japan) for this winter, and have now told Kotaku that Final Fantasy VI is on the way too.
You would think the big sales success of these would result in porting of many more Role-Playing Games of yesteryear, but they Japanese studios are playing the Disney Vault approach with these as ever. RPGs work on touch (even better with tilt support), whereas platformers are a mess.
I'm so big a fan especially of FFIV that I considered buying a PSVita at one point just so I could finally play the sequel. FFVI is right neck-and-neck with IV as my favorite in the series. I've wanted them legitimately on my phone for ages. If only there were an "original graphics mode"...
