I guess there's no one in the game world who knows Duke's name anymore. Especially after the third game Duke Nukem Forever is going to go on for 14 years, with a bad reputation Duke Nukem is back with his computers, made up of my favorite games, Duke Nukem 3D.
You may have just played Duke Nukem Forever. You may even have finished Duke Nukem 3D on several occasions. But I'm a partisan of this package collection.
