Zero Escape, Danganronpa, Immortality and Her Story, "basically any visual novel in the Mystery genre" probably qualifies to some extent? Frog Fractions and any other game relying on subverting expectations probably qualifies.
Beyond that... hmm. Undertale? Deltarune? I guess the third "Don't spoil me" genre for me is "games where the sheer joy is in being On the Ride". I played Undertale exactly one time and never touched it again and I'm more than happy with that experience, it was a single moment in my life and I think having it Be That Way actually feels better on some level. I'd probably put disco elysium on this list too.
Maybe the answer is just "games with writing that I like" lol
PS zandra we need to play AI: the Somnium Files sometime
