Final Fantasy IV (???????????IV ,Fainaru Fantaji Fo?) is a console role-playing game developed and published by Square (now Square Enix) in 1991 as a part of the Final Fantasy series. The game was originally released for the Super Famicom in Japan, but has been ported with minor changes to the Super Nintendo Entertainment System as well as by TOSE to the Sony's PlayStation, Bandai's WonderSwan Color, and Nintendo's Game Boy Advance. In May 2007, Square Enix announced that it was developing a remake of the game for the Nintendo DS. The game was re-titled "Final Fantasy II" during its initial release in North America due to it being the second of the series released there, but later localizations used the original title.
The player takes the role of Cecil, a Dark Knight from the kingdom of Baron, on his journey to save the world from the evil Golbez. Struggling to prevent Golbez from acquiring powerful Crystals, Cecil learns of his heritage and travels through three realms to battle Golbez's minions. His lover, best friend, and other warriors join him for the adventure.
Final Fantasy IV introduced innovations that became staples of the Final Fantasy series and role-playing games in general. Its "Active Time Battle" system was used in six subsequent Final Fantasy games. Its character-driven plot, use of the new technologies (such as Mode 7) and critically acclaimed score by Nobuo Uematsu has prompted critics to consider Final Fantasy IV one of the greatest games of all time.
