モノリスソフト
While at Squaresoft, Takahashi realized that the company intended to focus on the "Final Fantasy" series, and that sequels to the "Xenogears" series were becoming unlikely. He then decided to leave and start his own software development company. In October 1999 he left Squaresoft to start a new company, Monolith Soft, together with Hirohide Sugiura.
