Final Fantasy Adventure, which came out in 1991 for the Game Boy and was actually not a Final Fantasy game but instead the predecessor to Secret of Mana, got a remake in 2003 for the Game Boy Advance called Sword of Mana, which isn’t a strict remake but in fact overhauls just about everything from characters to story sequences, and is now getting yet another remake, to be released in 2016, for iOS, Android, and Vita. sauce
Man, I really want this game to release to the 3DS as well. Ugh, oh well at least I have an android machine tablet to play it on if worse comes to worse. ^^; XD
