Duke Nukem Forever, Aka DNF (Did Not Finish), so named because that's how long it took to finish it, was a game released in 2011 after a whopping 15 year development cycle, which only resulted in a abortion of mediocrity of a game. The game was thought to never be released and was the butt of many jokes, and only became a bigger joke when it was actually released to the dismay of the Duke Nukem fanboys who couldn't even defend this crap.
