the idea of remaking ff3j on gba sounds great, but because gba's target is younger children, it will probobly suck, because of the reduced difficulty, "cute" sprites, and the bad words will be replaced with words "uh oh" and stuff like that. :(
don't mess with fine works of art, but don't get me wrong i think a remake on gba would be great, but if u face reality, you would probobly think of it like legacy of great intention to resurrection of the dark dragon
