Nintendo Software Technology (or NST) is an American video game developer located inside of Nintendo of America main headquarters, based in Redmond, Washington. NST was created by Nintendo as a first-party developer to create games for the North American market, though their games have also been released in other territories such as Europe and Japan, exclusively for Nintendo consoles. Although the development team is based in North America, there is a traditional Nintendo and Japanese-centric design applied to the development of the software. Co-founders Claude Comair (co-founder of DigiPen) and Scott Tsumura retired in 2002 and 2006, respectively. NST is currently headed by Shigeki Yamashiro.
