I just realized a Zelda game is going to outsell a mainline Final Fantasy in Japan (like in a comparative sense. Wind Waker didn't outsell FFX, Twilight Princess didn't outsell FFXII, Skyward Sword didn't outsell FFXIII, etc.)
This is a first, right?
Same year for the launch
FC Final Fantasy 520.000 Square 18/12/1987
