When I was a kid, one of my friends would refuse to go into caves in Skyrim cause they didn’t like being underground. I remember thinking “damn, you’ve locked yourself out of like 90% of the game but whatever floats your boat”
I had a similar experience with Hollow Knight. Mind you, the entire map is underground, but there are certain very deep parts that are incredibly claustrophobic and I avoided them as much as I could.
Monster Hunter Rise, although it’s not exactly open world
