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 the 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 in December 2006, where it was sold both as a standalone title and as part of a bundle with the Xbox 360. Other regions received only the game itself, with a release in August 2007.
