Here's a pretty amusing chronicle of the Duke Nukem Forever project  that also contains lists like:

Things have been accomplished between Duke Nukem Forever's announcement on April 28th, 1997 and its death on May 6th, 2009...

• 30 Final Fantasy Games, 2 Movies, an Anime Series & Concert
• 14 GTA games
• 9 Zelda games & 6 handheld remakes
• 2 Sims games & 15 expansions
• Over 75 games based in the MegaMan universe, and 12 games featuring MegaMan universe character cameos.
• Over 50 games based in the Star Wars universe.
• Mario has appeared in 58 different video games.
• Every Massive Multiplayer Online game and expansion with the exception of Meridian 59.
• Every Dance Dance Revolution and Bemani rhythm game
• Every Pokemon game released outside of Japan.
• Every Unreal, every Unreal Tournament, and every game that has used any of the Unreal engines.
• Quake 2, 3, 4, and countless games that have used their engines.
• Every Tony Hawk and extreme sport spin-off game.
• Daikatana began development 10 days before Duke Nukem Forever- Unfortunately no one was made John Romero's bitch when it hit retail shelves on May 23rd, 2000.
• 3DRealms and Remedy bring Max Payne and its sequel from concepts to finished games, porting both to Xbox and PS2.
• Valve released both Half-Life 1 and 2, with several expansion packs and countless mods for each.
• Every version of Counter-Strike and Counter-Strike Source were developed.
• Every Thief game.
• Black Isle was formed, released seven titles and was shut down.
• The Elder Scrolls III: Morrowind and IV:Oblivion, and the entire Baldur's Gate series.
• Wizards of the Coast has printed six Core Sets, 30 Expansion Sets of Magic: The Gathering. If someone bought one of every single card printed since DNF was announced, they would have a collection of approximately 101,742 cards.
• Every installment of Metal Gear Solid released to date, as well as Ghost Babel (MGS for the Gameboy) and the Metal Gear Acid series for PSP. And it is likely that the the apparent conclusion of Solid Snake's legacy, "Guns of the Patriots," will come out before DNF.
• A garage full of programmers in Croatia (Croteam) developed the engine and created the game Serious Sam. Since then there have been multiple sequels and console ports- all off a fraction of the money 3D Realms has blown on DNF's development.
• Every 3D Prince of Persia game.
• Aside from Wolfenstein 3D, every single First Person Shooter based during World War II, including the entire Medal of Honor series.
• While DNF has been in production, Blizzard Entertainment, another studio famous for delays, has released four full games(Starcraft, Diablo 2, Warcraft 3, and World of Warcraft), with expansions for all of them.
• Bioware released Neverwinter Nights with two expansions, Star Wars: Nights of the Old Republic, and Jade Empire. All games are deep, lengthy RPGs that demand multiple playthroughs.
• The entire Halo trilogy.
• Every Gran Turismo game.
• Team Fortress 2

Things that have taken less time than Duke Nukem Forever's Development:

• The Beatles formed, released every single one of their albums and broke up. During this time they also toured the world several times.

• The United States' entire program to put a man on the moon, from Kennedy's challenge to the landing.
  
  • The Empire State Building (Jan 1930 - May 1931)

• The American War for Independence
• The United States Civil War
• World War I
• The United State's involvement in the Vietnam War.
• World War II and the entire Manhattan Project. Yes, even the complete development of the atomic bomb took less time.

LOL. Fantastic.

A phenomenal list. Good riddance Duke. You've tortured the community long enough.

Haha, amazing.

So there you have it folks, show's over after 12 years and 9 days, less time than it took Barack Obama to go from his first election as an Illinois Senator to becoming President of the United States... And all we have to show for it are a few videos and screen shots.
