I don't really have a ton to say about them because I am bad at video games. I just despise the mechanic of Permadeath+Randomization. Everything about the genre screams "get good" while punishing all the central premises of learning. It's just random difficulty while feeding you semi-similar levels on the supposed "beginner levels". Every so often you'll have some bullshit happen that wipes all of your progress, with not a single save point in sight.
Look I'm playing games to have fun, not to feel like some super badass that has mastered every possible mechanic a game can throw at you based solely on the beginner levels. It just feels like the genre exists to punish you, rather than to foster enjoyment.
I love roguelikes because you can try out different strategies and if you screw up you can just start over and since you're starting over all the time you don't have the problem of coming back to a game and trying to remember where you left off. They also (usually) give you time to think about and plan your next move, and they don't require any kind of technical skill like more action-y games do, which makes me feel less pressured/overwhelmed. They're difficult but I've always seen them as a fun, engaging challenge that I don't really expect to win - to me, "get good" makes me think more of multiplayer games like FPS's and MOBAs and stuff like that.
It may also help that I'm a bit of a masochist, I also enjoyed(?) Getting Over It which is explicitly designed to punish you instead of fostering enjoyment. I guess part of why I play games is to get the sort of challenge that I don't get irl.
Different strokes for different folks.
