My favorite roguelike might be ADOM, I've played it before it even hit Steam, a really long time ago in all its ASCII glory. :) Heck I still switch to ASCII-mode when I go play it, I'm just used to that and it's faster for me to process! :D

But I've also tried out others like Cogmind and Caves of Qud and a bunch more. I think I'd play Cogmind a lot more if it could be scaled better. Caves of Qud I still need to delve into deeper, but I did have some fun roaming around and getting into deep caves (and ultimately get killed).
A non-Steam one I like is Elona, it is a very quirky originally-Japanese RPG-roguelike hybrid. Can recommend Elona+ if you want to give it a go, it's free to download and play.

Card battle games, my favorite is probably Slay the Spire (Which I consider a Roguelike Card Game) and Star Realms, but there are other close contenders. Recently I got into Ascension again and am playing the heck out of that one now. System Crash is a hidden gem that I acquired recently and still need to get into.

Since Slay the Spire entered the gaming world, more card battle games in that style are popping up. Blood Card and Fate Hunters come to mind. They're pretty decent, but not as smooth yet as StS, but I had some fun playing them.

But besides those, I can also enjoy Magic the Gathering, or simpler card games like Crunch Time!, and Love Letters. On my phone I play Hot Death Uno, but also Klaverjassen and Cribbage. Really, almost anything goes. :D

Monster Train happens to be in my wishlist. 100% Orange Juice I've played a few times, it's a funny board/card game, but it's not luring me in enough to really play it. I should give it a spin again sometime.
