Final Fantasy X-2 is a 2003 role-playing video game developed and published by Square for the PlayStation 2. Unlike most Final Fantasy games, which use self-contained stories and characters, X-2 continues the story of Final Fantasy X (2001). The story follows Yuna as she searches for Tidus, the main character of the previous game, while trying to prevent political conflicts in Spira from escalating to war. Final Fantasy X-2 was the first game in the series to feature just three player characters and an all-female main cast. The battle system incorporates Final Fantasy character classes—one of the series' signature gameplay concepts—and is one of the few entries to have multiple possible endings. The soundtrack was created by Noriko Matsueda and Takahito Eguchi in lieu of long-time Final Fantasy composer Nobuo Uematsu. The game was positively received by critics and was commercially successful, selling over 5.4 million copies on PlayStation 2 and winning a number of awards. It was the last Final Fantasy game to be released by Square before it merged with Enix in April 2003. The game was re-released in high-definition for the PlayStation 3 and PlayStation Vita in 2013, alongside Final Fantasy X, as Final Fantasy X/X-2 HD Remaster; this version was later released for the PlayStation 4 in 2015, Windows in 2016, and the Nintendo Switch and Xbox One in 2019. As of September 2021, the Final Fantasy X series had sold over 20.8 million units worldwide, and at the end of March 2022 had surpassed 21.1 million units sold around the world.
