Yeah! Dungeon Crawl Stone Soup is my favorite but I have played a lot of traditional roguelikes
Caves of Qud is pretty newbie friendly in terms of UI and how easy the controls are to learn. It has a really cool aesthetic and world to explore, and while the combat is not the strong point, it has really robust cooking, trading, mutation, and cybernetics systems. Plus it's much more fun to simply explore in that game, finding settlements and traders and factions and ruins is a really fresh experience compared to the usual endless dungeon diving of the genre
Infra Arcana is a really streamlined and simple, but fun, lovecraft inspired dungeon crawler. It's probably one of the easiest ones to just pick up and play if you're somewhat familiar with the genre and it's quite addicting thanks to the simplicity
Tales of Maj'eyal is pretty accessible too, it just requires you be willing to read a lot of lengthy skill descriptions and decipher dozens of lines of stats on every item. Compared to some other games it's extremely combat focused and you are from the start semi-locked into one of several classes with unique skill trees, synergies, resource systems, and more. For example one of the ranger skill trees focuses heavily on "mark"ing a target and other abilities key off of that, meanwhile other classes might care about how many cursed items you wear, your HP, a mana/stamina pool, etc. I'd recommend this one if you want a Diablo 2 roguelike cuz that's what it reminds me most of, right down to having "elite" enemies who drop piles of color-coded-by-rarity loot
Cataclysm: Dark Days Ahead is a post apocalypse/zombie survival roguelike and while I never got very good at it it's really fascinating and extremely deep, the focus is on just day to day survival but it's got vehicle/base building, hunger and thirst and cooking systems, and massive amounts of crafting tree stuff to play with. My personal problem is that I can never live long enough in this game to do any of the cool stuff I read about ;_;
I'd also be remiss not to mention NetHack because it's so infamous and it's also the first roguelike I ever played. I'm not sure if I'd super recommend it over more modern options but it is extremely charming and a good baseline to start from. It's got pretty much all the things that you would expect, for better or for worse: potion/sPost too long. Click here to view the full text.
