Have you played Outer Wilds? It’s kind of a walking simulator in the sense its 's heavy on discovering the lore and exploration instead of action and defeating baddies BUT it has space flight realistic physics and a solar system simulation. It’s a pretty nice and chill game with space exploration and a constant feel of dread when you step out of the ship but it does not have multiple ships or multiple alien forms. Still, it’s the best game I played recently.

Yoshis Island Silent Hill Shadow of the colossus Majoras Mask Outer Wilds

There are a lot of games I played a lot of times but maybe because I had no others and had a ton of time. Nowadays I would only replay Yoshis Island and Shadow of the colossus. I dont know if would replay SH but I played it a ton when young and it cemented my love for survival horror games. I only went through Majoras Mask once or twice, I was more of a Playstation kid than a Nintendo one. I recently played Outer Wilds and it was an awesome unexpected experience.
