I've browsed the category on Steam, but my eyes glazed over after about the 10th page of Unity walking simulators, anime schoolgirls, and RPG Maker games with default assets. I'm also looking for something that'll really get under my skin rather than casual action-horror titles.
Examples of horror games (both old and new) I particularly like to give you an idea of what might resonate with me:
- Silent Hill 2
- Lost In Vivo
- IMSCARED: A Pixelated Nightmare
- Clock Tower
- Five Nights At Freddy's (I might catch some flak for this one, but it was a genuinely clever and well-executed premise before it got memed to death and I'll die on that hill.)
- ANATOMY
- Stories Untold
Horror games a lot of people seem to like but I don't:
- Doki Doki Literature Club (it was a bit too anime for me)
- Amnesia: The Dark Descent (I finished it, it was okay, never really scared me though)
1: I'm gonna start this comment by suggesting that you play every single game by Kitty Horror Show. Most of those games are hour long experiences and not true "games" but holy damn they're cool. There's no narrative connection between them so feel free to start from the most recent since those are the best and work your way back.
2: Have you played Alien: Isolation? It drags a bit in the second half but the atmosphere and execution of hiding from the Alien is great. Plus I loved walking around that 70s sci-fi ship and I wish I had a VR headset so I could do it again.
3: Also in the AAA horror sphere: Death Stranding. My GOTY the year it came out, the sequences of sneaking past monsters with powers you don't understand armed with only vials of your own blood are a standout moment, and the theme of connecting people who are all quarantined from each other across America hits pretty close right now. Like Alien it gets worse in the latter half when you start to get good at circumventing the monsters, but it never gets bad.
