This thread is created with the intention of General Discussion and Random News posts for what is (to date) the most infamous case of a Game taking Way too long to finish.
First the Background on the game (if memory serves me well enough).
After Duke Nukem 3D was finished, 3D realms were busy working on More games that utilised the Build engine (shadow warrior, Blood). In 1997, they announced a Sequel to much Joy amongst the Majority of the PC gaming community. Duke Nukem forever was Being made Using the Quake II engine (before the Uncountable changes to the engine). Near the completion of the game (and after releasing a E3 Trailer for the game) they felt that the game couldnt compete with the current crop of games (2001 hearlded the Launch of the XBox) so they scrapped the project Completly (as well as taking all information such as Screenshots and Videos from the game from the 3D realms Site).
Here are the Videos
