In addition to Mobile Light Force, Final Fantasy VII was also rated by the ESRB as a PlayStation 3 and PSP game. (Thanks for the tip Jon!!) That makes it a candidate as a downloadable PlayStation Classic on the PlayStation Store.
In April Square Enix re-released Final Fantasy VII International as a downloadable game in Japan for 1,500 yen ($15). How much would you pay for a disc-free version of Final Fantasy VII?
