Blue Dragon (Japanese: ブルードラゴン Hepburn: Burū Doragon) is a role-playing video game developed by Mistwalker and Artoon and published by Microsoft Game Studios exclusively for the Xbox 360. Blue Dragon is based on a design by Final Fantasy series creator Hironobu Sakaguchi, who also supervised development and wrote the plot. It is both Mistwalker's debut title and the first title to be helmed by Sakaguchi outside of Square Enix. The game was released in Japan on December 7, 2006, where it was sold both as a standalone title and as part of a bundle with the Xbox 360 (including the game, the Xbox 360 system itself, and a Blue Dragon console skin). Other regions received only the game itself, with a release in Europe on August 24, 2007, and in North America on August 28, 2007.
