Nintendo Software Technology is an American video game developer. 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. 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 Scott Tsumura and Claude Comair retired in 2002 and 2006, respectively. NST is currently headed by Shigeki Yamashiro, and is located inside of Nintendo of America's headquarters in Redmond, Washington.
