The music of the Final Fantasy Tactics video game series, composed of Final Fantasy Tactics, a spin-off of the main Final Fantasy series, Final Fantasy Tactics Advance, a spin- off game from Final Fantasy Tactics, its sequel, Final Fantasy Tactics A2: Grimoire of the Rift, and Final Fantasy Tactics: The War of the Lions, a remake of Final Fantasy Tactics, was primarily composed by Hitoshi Sakimoto. The only input from Nobuo Uematsu, the main composer of the Final Fantasy series, was in the soundtrack to Tactics Advance. He was assisted by Masaharu Iwata in composing the music for Final Fantasy Tactics. The Final Fantasy Tactics Original Soundtrack, a compilation of almost all of the music in the game, was released by DigiCube in 1997, and re- released by Square Enix in 2006. As of 2008, no separate soundtrack has been released for Final Fantasy Tactics: The War of the Lions. The soundtrack was well received by critics, who found it to be astounding and one of the best video game music soundtracks in existence at the time of its release.
