The system failed to become popular but Sopwith became a popular game for the IBM PC and compatibles. A sequel "Sopwith 2" was actually a newer version rather than a different game, but included many extra features, such as Oxen and birds. Sopwith was also ported to the Atari. The original author, David L. Clark, later created Sopwith - The Author's Edition with several extra features including missiles. This version of sopwith is based on the source for the Authors Edition.
