Mistwalker Corporation is an American-Japanese video game development studio. The company was founded in 2004 by Hironobu Sakaguchi, best known for creating the Final Fantasy series. The company has created both game franchises such as Blue Dragon and Terra Battle, and standalone titles including Lost Odyssey (2007) and The Last Story (2011). With the financial problems caused by Final Fantasy: The Spirits Within, and his growing dissatisfaction with management, Sakaguchi decided that he wanted to make games outside Square. Mistwalker's first two titles were Xbox 360 RPGs; Blue Dragon (2006) and Lost Odyssey. Following The Last Story for Wii, Sakaguchi and Mistwalker changed to focus on in-house mobile titles. The original Terra Battle saw widespread success and acclaim, leading to further mobile projects.
