I realized I only have the patience for (relatively) short singleplayer games (I just hate grinding in general in video games).
Some of my favorites are:
NieR:Automata (around 40-60 hours of playtime. This one might seem ironic, as it does have some repetition, but it has no grinding and always something interesting new. It also has by far the best story of any game I've ever played)
The Beginners Guide (~4 hours of gameplay. It is super unique and has a cool take on psychology, which I haven't seen in any other game or movie. But you need to play it all the way to the end for it to make sense)
Noita (hard rouge like, and the only one I really enjoy. It's also very unique in its genre and you can always save and quit.)
Balatro (technically also a rouge lite, but with playing poker hands. It has short rounds and is a casual game, if you only have a few minutes ans don't know what to play)
Hijacking this comment for recommending my two favorite rouge lites Noita and Balatro. Both have the possibility to save and quit at any time.
