There's tons of variants, probably the most out of any of the roguelikes. ZAngband "Zelazny Angband" took the tolkien elements and added elements from Roger Zelazny's Chronicles of Amber series. SAngband "skills angband" added weapon skills and probably tons more. OAngband "opinion angband" scratched the itch of its developers about how Angband should work. MAngband was (wait, IS! it had a release in 2020) a mind-blowing multiplayer Angband variant.
Tales of Maj'Eyal https://store.steampowered.com/app/259680/Tales_of_MajEyal/ is the continuation of an angband variant called Tales of Middle-Earth / T.o.M.E., which name change I gather was necessary because DarkGod wanted to go commercial.
I wanted to link to [0] for a complete list but it's having struggles today. [1] and [2] have lists but I would guess that roguebasin's list would be more authoritative.
I got started with moria/umoria on the Amiga, which had beautiful graphical tiles. Then I played quite a lot of moria/angband in the terminal on Linux (occasionally dabbling with the tileset/gui versions).
It's an interesting game.

I still remember how delightfully different the game became with multi-player - mostly because it wasn't lock-step turns (a la Civilisation), but tick-based. I still think there's room for a multi-player rouge-like - but Mangband is not it for me.
But it remains an illuminating lesson in game design ("Completely change the feel of your game, with this one wierd t(r)ick!" :)
ZAngband is, sadly, very dead -- the last release was in 2003. I miss it.
Another wacky, fun (and, sadly, also dead) variant was Steamband, a steampunk-themed variant with completely new classes, races, and monsters: http://angband.oook.cz/steamband/steamband.html
TOME is such a great game. I've played Nethack since early 90's, thereafter Angband and Zangband and finally TOME. TOME is very polished, slick, beautiful, full of depth, different challenges and styles. Also actively maintained. Sunken so many hours while listening to talk radio.
Sil http://www.amirrorclear.net/flowers/game/sil/ is kind of an Angband variant but embraces the middle earth theme a lot more and has removed a lot of stuff.
