Horror Games

[Turbo Kid]

Until Dawn
Dino Crisis
Peter Jackson's King Kong as much of the game is like a Jurassic Park movie and dinosaurs are scary.
Resident Evil 2
Resident Evil 4
Eternal Darkness Sanity's Requiem
The Castlevania series. (and by extension the Bloodstained series)
Dead Space
SOMA
Dredge
Splatterhouse 3
Zombie Revenge
The Thing

I also like games where you're the monster like Maneater, The Darkness, The Darkness II, Stubbs the Zombie, Tales from Space Mutant Blobs Attack, Party Hard, Carrion, and Tecmo's Deception series

And of course I have to mention some good comedy horror like Lollipop Chainsaw, the Luigi's Mansion games, and Evil Dead: Regeneration

-Silent Hill 2
-Killer 7
-Deadly Premonition
-Cosmology of Kyoto
-Garage Bad Dream Adventure
-Hellnight
-Rule of Rose
-The Dark Eye
-Shivers 2 (not scary tho)

Maybe SMT: Nocturne and Drakengard 1 too as they clearly have horror influence. But the scariest game for me is still Dark Messiah of M&M because of the damn spiders!!!
