I did some digging around and found out that the Plutonium Pak and the Atomic Edition requires disc-checking to run the game to read a file off the disc. However the vanilla v1.3D version of the did not introduce disc checking after installation.
Talk:Duke Nukem 3D
Looks like the Plutonium Pak adds disc-check DRM to Duke Nukem 3D
I have added this to the page.
Duke3D on a lot of different soundcards and modules
Wow, the Roland MT-32 version is so great!
Duke Nukem Forever 2013 Mod: any feedback?
I added the link to the Duke Nukem Forever 2013 Mod because it seems quite well done and interesting due to the lack of Duke Nukem games but I don't have time to test it yet so if anyone can give a feedback to know if it's worth mentioning it or not would be great. Thanks.
This is a fun mod, definitely worth including. The levels are interesting recreations of the trailer scenes and it has a great ending.
