There are Final Fantasy Legend, Final Fantasy Legend 2 and Final Fantasy Legend 3 for the old (first) Gameboy. These are not really Final Fantasy games though.. they are actually the first 3 games in the
SaGa series. They are called SaGa in Japan, Square just decided to call them FF outside Japan, perhaps because FF was far more well known already? I don't know.
Final Fantasy Adventure is also a game for the old Gameboy, and it's
also not really a Final Fantasy game. It's actually the first game in the Mana series. It was called Seiken Densetsu in Japan, and Seiken Densetsu is the Japanese name for the Mana series. The second Seiken Densetsu game was for SNES and was called Secret of Mana in the US, which all of you should have at least heard of
