Dissidia Final Fantasy

Dissidia Final Fantasy is a 2008 fighting game developed and published by Square Enix for the PlayStation Portable. It was released in Japan on December 18, 2008, in North America on August 25, 2009, and in Australia and Europe in September, as part of the campaign for the Final Fantasy series's 20th anniversary. It was then re-released in Japan, based on the North American version, as Dissidia Final Fantasy: Universal Tuning, on November 1, 2009.

The game features characters from different Final Fantasy games and centers on a great conflict between Cosmos, the goddess of harmony, and Chaos, the god of discord. The two summon multiple warriors to fight for their sides in their thirteenth war. During the story, the player controls the ten warriors chosen by Cosmos, the protagonists from the first ten Final Fantasy games, in their journey. The game's English and international versions give access to other features such as an arcade mode.

Dissidia originated from Kingdom Hearts director Tetsuya Nomura's desire to create a spin-off for the franchise, which was later changed to the Final Fantasy series. Besides designing the characters, Nomura worked with the Square staff with the desire to make it appealing to Western players. Dissidia was well-received commercially and critically, with positive reviews and sales of over 1.8 million. A follow-up titled Dissidia 012 Final Fantasy was released in March 2011, featuring several new characters and gameplay elements.
