Well I must admit I was too excited for Duke Nukem Forever, and was left with 'some' disappointment. The game was pretty fun, but they should've kept it true to Duke and not bastardize it with a COD/ Halo clone.
Now, a group of people actually managed to create a Duke Nukem 3D mod based on the 2001 trailer for Duke Nukem Forever that 3D Realms promised would be in.

All you need is duke3d.grp from the Atomic Edition (If you bought it from gog.com or on Steam) and place it in the folder, and you're good to go.
