The original Final Fantasy released in Japan way back in 1987 (1990 in the U.S.), and as such Square Enix has marked down some of the games available on the Nintendo 3DS and Wii U.
Final Fantasy Tactics Advance has dropped from $7.99 to $5.59 on Wii U. This Virtual Console port of the GBA game is revered by many.
The 3DS also sees a few good deals. Both Final Fantasy Explorers and Theatrhythm Final Fantasy Curtain Call are half price: $19.99 (originally $39.99). These digital sales are currently available on the eShop through February 21.
