Games with Unintentional Creepiness

I love, LOVE, E.V.O. Search for Eden, but there is always something very weird about its music that just puts me off.

Below is a speedrun, but if you forward it to minute 4, yeah, you can see what I mean.

San Andreas always had this creepy vibe to it.

The aesthetics of Paladin's Quest were always creepy as fuck.

I feel like the general graphic style was inspired by French animation Fantastic Planet, with its alien, really bizarre environment. I find it charming, though.

The Sims 2 on GBA was creepy as shit.

Basically, you were the main character in show set in Strangetown and each "mission" was an episode.
And some of them were rather creepy.
Like, I remember one episode was about a mole-man killing people or something. Or another one where basically everyone disappeared and you were all alone. Never finished the game because some of the objectives were so obtuse, I couldn't figure out what to do next, so I was left wandering aimlessly, that was creepy too.
It might sound "intentionally creepy" and I believe it was but what makes it so work so well is that fact that most mission were funny, positive and light-hearted.
Then once in a while, the game hit you with some really creepy shit.

And also, this creepy music was playing all the time :
