Following the release of "Sonic &amp; Knuckles", Yasuhara quit, citing differences with Naka, and went on to develop games for Sega of America. Naka returned to Japan with developer Takashi Iizuka to continue work with Sonic Team, reuniting with Sonic the Hedgehog character creator Naoto Ohshima. In 1995, the mostly American staff completed "Comix Zone" and "The Ooze", the only games to bear the STI logo. STI completed one game in partnership with Sega AM1, "Die Hard Arcade".
