I got really deep into Caves of Qud (classic rogue like) after initially dropping it for being too difficult. It has a bit of a learning curve, but beyond that, it is really fun. Very engaging sci-fi fantasy world, lots of interesting things to do or see, some fun random quirks/jank, and very diverse character customization. I think what I love the most is that it’s a knowledge game, where you excel by learning some bits and tricks here and there, like the effects of cooking with certain ingredients or getting some special items with an important effect (aka cheesing stuff).

Also besides being a very hard roguelike, it is really chill in a way (also helpt by the music).

If you do have struggles with it, I can recommend giving roleplaying mode a spin, where you don’t have permadeath, or there is a website called qudzoo with some seriously good advice.
