Games with highest replay value?

Apologies if this has been asked a lot/recently, but I hadn’t seen this specific question instead of the usual “which big name game haven’t you been able to get into”, so thought I’d give it a shot. Maybe even see if there’s hidden gems out there outside of the more obligatory rogue-like/lite.

Genre-wise, for me it’s Metroidvania to no one’s surprise where the games tend to be fairly short in the modern age but completing them is so satisfying and each replay is about beating your previous time or completion percentage. I’ve played through Super Metroid and Metroid Dread fully twice but played through each pretty deep on a few runs afterward. Same with Hollow Knight.

Otherwise kind of as a one-off, I played Kingdom Hearts II and beat it every summer from 5th grade-12th grade.
