I dunno. Wasn't Duke Nukem 64 basically a censored version of Duke Nukem 3D?
Largely, but the developer did do some significant work with several level remixes and some new weapons and graphics. I think it's different enough to be interesting, but not different enough that I see anyone going out of their way to get the game back out on the Online Pass.
If anything, I think the RE2 port should take priority. Not only was it a great port, but Capcom has been, sort of, "vaulting" the original RE games as they get remade. Right now, the only way to legally play the first 3 games as they were, is to go through GOG. Otherwise, the option are the remakes. And in the Switch's case, those remakes are only available as "cloud" titles.
