I know the feeling. I even though I kind of want to play some bigger single player games, I tend to put those off to spend hours playing comfort games. More generally, I get really overwhelmed by really complex games. I still want depth, but I want it to come from gameplay interactions rather than wrangling the controls or messing with a giant character build or something.
That's why I end up playing a lot of things like card games, roguelikes, etc. Things that are really easy to start playing, easy to keep repeating, but which still provide interesting, varied experiences. Think about it, if I play something like Slay The Spire, all I have to do to learn the controls is to click and drag a card. There are builds, but those builds are constructed through a bunch of small, manageable choices.
Complete left field recommendation: It's not a repeatable game, but if you somehow haven't played it yet, Portal is a masterclass in this kind of depth without complexity design and perfectly tutorializes what little you do have to learn.
This is nice. I was really worried there would be some last minute funny business with Cuomo, but things worked out for once!
