"Final Fantasy is a console role-playing game created by Hironobu Sakaguchi, developed and published in Japan by Square (now Square Enix) in 1987, and published in North America by Nintendo of America in 1990. It is the first game in Square's Final Fantasy series. Originally released for the Nintendo Entertainment System, Final Fantasy was remade for several video game consoles and is frequently packaged with Final Fantasy II in video game collections. The story follows four youths called the Light Warriors, who each carry one of their world's four elemental orbs which have been darkened by the four Elemental Fiends. Together, they quest to defeat these evil forces, restore light to the orbs, and save their world.
