I do like some things by fans myself. I make my own t-shirts and some other things (like flooring)... most of all, I WANT to make lots of things.
As far as Duke Nukem commercially available items, I have all of them that I know of. I was actually a member of the Resaurus Forums before I was a member of 3D Realms forums.
Since the 90's, I have had a neurotic (not to me, but to others) approach to gaming... I bought the Duke Nukem Action figures from Toys R Us the day of release. I got the comic book exclusives as soon as I could find them also. When I play(ed) Duke Nukem 3D, I usually open up the box, review the manual a bit and then maybe look at the posters I have, get on a Duke Nukem Shirt, if I don't have one on already. Then I set an action figure of said game on top of my monitor or desk next to me and play the game. Is just a total experience for me. I do the same with the older Start Wars movies and games.
Yeah, I am nanners, but I have some very thorough fun.
