Corrections: DukeNukemForever was initially mistitled DukeNukem 3D, possibly out of a subconscious wish that DukeNukem 3D was the latest in the franchise.
The studio is 3D Realms, responsible for the once-badass DukeNukem and the way-less-badass DukeNukemForever, a project that had to eventually be finished by Gearbox after over a decade in development hell.
