This is an English translation the original Japanese version of Final Fantasy IV for the SNES.
The game's story follows Cecil, a dark knight, as he tries to prevent the sorcerer Golbez from seizing powerful crystals and destroying the world. He is joined on this quest by a frequently changing group of allies. 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 five subsequent Final Fantasy games, and unlike prior games in the series, IV gave each character their own unchangeable character class.
