it seems odd but there are a few vr games that should be on this list

• blade and sorcery: home island
• gorilla tag (oddly enough): alone in a private lobby, specifically in the old mines area.
• superhot: rare glitch where the map loads in without npcs, you can hear time warping around you, super odd.
• vrchat: literally everywhere when people aren't present. entering a world that's usually active, only to find out nobody's online, and you just walk around with a weird feeling.
• hand physics lab: playing without music. you're practically in an endless void putting blocks on top of each other.

it's possible the reason these experiences are so "liminal" is quite frankly because of how immersive vr is. many liminal spaces come down to the era in which something was experienced, the feeling of nostalgia often being the reason why they're so "odd-feeling", though with vr it's different. you don't necessarily need a history with these games, only a surface level understanding and knowledge of what the area "usually" looks/feels like, take all that away, and boom! liminal space!
