Eternal Darkness. Cosmic Horror is under-represented in video games imo, and it is one of the ones that nails it. It's a bit dated, but the interesting story and sanity mechanics make up for it. It also has some good voice acting for the time. I also like how it's a survival horror that doesn't rely on jumpscares (which makes the single one in the game extremely effective). I would kill for a remaster or something. Hopefully Nintendo releases it on NSO if anything
