最终幻想XIII
Development of "Final Fantasy XIII-2" began around March and April 2010 and lasted about one and a half years. The game was unveiled at the Square Enix 1st Production Department Premier in January 2011. Many of the key designers remained in their roles from the previous game, and developer tri-Ace was hired to help with the game's design, art, and programming. The development team wanted to exceed "Final Fantasy XIII" in every aspect while making the story's tone mysterious and darker than the previous game. The game builds upon the Paradigm Shift battle system used in "Final Fantasy XIII" and includes a less linear overall design.
