Artoon (株式会社アートゥーン Kabushiki-Gaisha Ātūn) was a computer and video game third-party developer established in 1999. The team was primarily affiliated in the United States with recent and current MicrosoftXbox and Xbox 360 projects, although they had also worked with Hudson Soft and Nintendo on other platforms. Key Artoon personnel include Yoji Ishii, Manabu Kusunoki, Hidetoshi Takeshita, Yutaka Sugano, Masamichi Harada, Takuya Matsumoto and Naoto Ohshima. When the company formed, it drew personnel and talent from several of Sega's development teams, particularly those which worked on Sonic the Hedgehog (created by Ōshima), and Panzer Dragoon. The developer had approximately 85 employees. The company's focus was to create original game content for various consoles. Artoon became defunct when the parent company, AQ Interactive, filed for bankruptcy.
