Wasn 3D Realms once planning another game under the name Duke Nukem Forever?
Yes, the game now known as Duke Nukem Forever was originally referred to as Duke Nukem 4 in early 1997, while 3D Realms considered the idea of a new side scrolling Duke title which was referred to as Duke Nukem Forever. 3D Realms’ George Broussard once described the original Duke Nukem Forever side-scroller as “a really cool 3D side-scroller like Donkey Kong Country.” When plans for the side-scroller were abandoned, its name was too good to let go to waste, so Duke Nukem 4 has ever since been known as Duke Nukem Forever. The abandoned 3D side-scroller version will never be released due to legal reasons, nor will any screenshots. Sorry.
