Final Fantasy IV is the fourth game in the Final Fantasy series. Originally released for the Super Nintendo Entertainment System, the game was subsequently re-released for the PlayStation, the WonderSwan Color, the Game Boy Advance and the Nintendo DS. It was originally released in North America as Final Fantasy II. This altered numbering system caused the game Final Fantasy VI to be numbered Final Fantasy III, leading to quite a bit of confusion when the PlayStation game Final Fantasy VII (which retained the number VII) came out. A sequel, Final Fantasy IV: The After Years, was released for Japanese mobile phones in February 2008. The sequel was released via WiiWare in the US on June 1, 2009.
