If you like CDDA there's a cyberpunk/scifi TC with a true ending: Bright Nights.

I am aware it exists, but I have kinda put it off as I often feel that forks fail to deliver better than the original (worth to mention as a worthy fork is UnNetHack!). Is BN any good? Worth playing if your not into the magic stuff?

Mutations, technology, crafting...

yes, I'd say it is.

If you want Nethack in space a la pulp magazines/scifi from the 50's, check P.R.I.M.E.
