The video game Duke Nukem Forever spent more than 14 years in development, from 1997 to 2011. It is a first-person shooter for Windows, PlayStation 3 and Xbox 360,[1] developed by 3D Realms, Triptych Games, Gearbox Software and Piranha Games. It is the sequel to the 1996 game Duke Nukem 3D, as part of the long-running Duke Nukem video game series. Intended to be groundbreaking, it became an infamous example of vaporware due to its severely protracted development schedule. Director George Broussard, one of the creators of the original Duke Nukem game, announced the development in 1997, and promotional information for the game was released from 1997 until its release in 2011.
After repeatedly announcing and deferring release dates, 3D Realms announced in 2001 that Duke Nukem Forever would be released "when it's done". In 2009, 3D Realms was downsized, resulting in the loss of the game's development team. Statements indicated that the project was due to "go gold" soon with pictures of final development. Take-Two Interactive, which owns the Duke Nukem Forever publishing rights, filed a lawsuit in 2009 against 3D Realms over their "failure to finish development". 3D Realms responded that Take-Two's legal interest was limited to their publishing right. The case was settled with prejudice and details undisclosed in 2010.
On September 3, 2010, 14 years after the start of development, Duke Nukem Forever was announced by 2K Games to be in development at Gearbox Software,[2] with an expected release date of 2011. Duke Nukem Forever was released on June 10, 2011, to mostly negative reviews. It holds the Guinness world record for the longest development for a video game, though this period has been exceeded by other games since.
