Probably the only example more famous than Duke Nukem 3D is Doom, created three years before.
The game is considered a real classic and one of the games that made the genre of 3D first-person shooters so famous. 3D Realms was a new division of Apogee, dedicated to 3D games, and Duke 3D was their second title, after Terminal Velocity. The game is the sequel of Duke Nukem and Duke Nukem II, two shooters/platformers created by Apogee Software. Duke Nukem 3D is a sci-fi first-person shooter created by 3D Realms and published by GT Interactive Software for PC in 1996.
