Short answers, pulled from the story.
Ivalice is a fictional world created by Yasumi Matsuno that serves as the setting for Final Fantasy Tactics (1997), Final Fantasy XII (2006), and several other titles developed by Square Enix. It is a high fantasy world focused on political drama and the stories of everyday people, blending medieval and science fiction elements.
Yasumi Matsuno created Ivalice, originally for Final Fantasy Tactics in 1997. Matsuno was a game designer and writer previously known for his work on the Ogre Battle series at Quest Corporation. He left Square Enix in 2005, after which the company continued developing games set in the world he built.
Games set in Ivalice include Final Fantasy Tactics (1997), Vagrant Story (2000), Final Fantasy Tactics Advance (2004), Final Fantasy XII (2006), Final Fantasy XII: Revenant Wings (2007), Final Fantasy Tactics A2: Grimoire of the Rift (2007), and the Return to Ivalice crossover within Final Fantasy XIV (2013). The mobile titles Crystal Defenders and Tactics S also use the Ivalice setting.
The Ivalice Alliance is a branded collection of games set within the Ivalice world that began release in 2006, following Matsuno's departure from Square Enix in 2005. Akitoshi Kawazu served as executive producer. The collection aimed to attract new players and included games outside the RPG genre.
As of 2025, Square Enix has no plans to set a new game within Ivalice. Kazutoyo Maehiro, who was directing a remaster of Final Fantasy Tactics, confirmed this in a 2025 interview, describing that project as a personal endeavor rather than a signal of broader company plans for the setting.
Final Fantasy XIV drew direct scenario inspiration from Ivalice, incorporated several Ivalice location names including Dalmasca, and added the Viera people as a playable character option. Producer Naoki Yoshida also hosted the Return to Ivalice crossover campaign within XIV in 2013, which featured characters based on figures from Final Fantasy XII and Tactics.
