Numerical Design Limited (NDL) was founded in 1983. They primarily completed contract work for government and
computer-aided design (CAD) clients in the computer graphics sector; however, they also did work for some game developers such as
Interactive Magic. This work led to the production of the NetImmerse game engine in 1997, evolving into Gamebryo by 2003. NDL was merged into Emergent Game Technologies (EGT, founded 2000, Butterfly.net until May 2005) in August 2005. NetImmerse then evolved to Gamebryo LightSpeed. During 2009 the development staff of Gamebryo was downsized, and by July 2010 the engineering office in
Chapel Hill, North Carolina was closed. On November 11, 2010, assets of EGT were offered for acquisition, including its
intellectual property (IP), in whole or in part. In December 2010, Korea-based Gamebase Co., Ltd., a longtime partner of EGT, finalized the acquisition of EGT assets and technology, and established a newly capitalized U.S. company, Gamebase USA. Gamebase USA is based in the
Research Triangle Park region of
North Carolina and is focused on continual development of the Gamebryo game engine. The newest version, Gamebryo 4.0, was introduced in March 2012. == Features ==
