Final Fantasy IV: The After Years is an episodic role-playing video game co-developed by Matrix Software and Square Enix, as the sequel to the 1991 title Final Fantasy IV. Originally released in Japan as a mobile game in 2008, an enhanced WiiWare port of the title was released in North America, Europe and Japan in 2009. In 2011, the game was bundled with Final Fantasy IV as the PlayStation Portable compilation Final Fantasy IV: The Complete Collection, which also included a new game; Final Fantasy IV: Interlude, which served as a bridge between the original game and The After Years. The game was remade for the Android and iOS platforms using the same style as the Nintendo DS version of Final Fantasy IV, and was later released for Microsoft Windows.
