Sega Consumer Research and Development Dept. #2 (nicknamed Sega CS2, which it was officially renamed to in 1994) was a video game research and development division within Sega. As the name suggests, it was the second "consumer"-specific R&D department created by Sega Enterprises. It was responsible for first-party Sega Game Gear titles, certain Sega Mega Drive titles with international appeal, RPGs for the Mega-CD, and certain early Sega Saturn titles. Notable developers who got their start at CS2 include Tadashi Ihoroi, Kazufumi Ohashi and Shinichi Higashi. It was later followed up by another department named Sega CS2.
