FormGen Corporation was a developer of business software and publisher of video games based in Scottsdale, Arizona.

FormGen was founded in 1987 by friends Randy MacLean and Robert Van Rycke in Bolton, Ontario.

It was a software producer and distributor, selling its text-based form generation program through Radio Shack stores in Canada.

[citation needed] The company advanced rapidly in the early 1990s when it made an agreement with id Software to distribute its new games, such as Commander Keen in Aliens Ate My Babysitter, Wolfenstein 3D: Spear of Destiny, Doom (shareware), and with Apogee Software (later 3D Realms) for Rise of the Triad and Duke Nukem 3D.

They claimed that Micro Star's sale of the Nuke It compilation of user-created maps and levels infringed on its copyright of the derivative works of Duke Nukem 3D and won the case on appeal.
