I dunno. Perhaps because I don't play a lot of games with exorbitant amounts of achievements but for me in games like Hollow Knight they were sort of a roadmap. The thing is, you can just complete the ones you want. In my playthrough on the switch (where some of the achievements were just hidden), I didn't get the same sense of having checked something off my list as I did when playing on steam. It's almost like since nobody can really see them there's no joy in it. But on steam I felt more pride in those same achievements.
