is primarily a series of video games developed by Monolith Soft and published by Namco. Xenosaga's main story is in the form of a trilogy of PlayStation 2 video games. Several side stories and spinoff projects have also been developed, as well an anime adaptation. The Xenosaga series serves as a spiritual successor to the game Xenogears, which was released in 1998 for the PlayStation by Square (now Square Enix). These two works have links through allusions, stylistic connections, and design similarities. The creator of both Xenogears and Xenosaga is Tetsuya Takahashi, who left Squaresoft in 1998 along with Hirohide Sugiura. Using funds from Namco, they started Monolith Soft and the Xenosaga project.
