I know that people love to meme about "liminal spaces" in Super Mario 64 but I noticed that 3D games from the beginning of that era often had that "eerie" feeling (especially in some levels like Surface 2 in Goldeneye, many PS1 games and less commonly Saturn since the games were often more colourful).
I think it's because they're trying to be lifelike while still being technically limited so they often reach the uncanny valley instead of showing proper environments and humans.
With limitations you also have less crowded areas thus feeling emptier than expected (it's noticeable with Mario 64's castle where there are only a few Toads in it).
I am guessing this is also why low poly horror games are quite popular recently, the brain often fills the empty space that the game cannot properly show.
