By psychological horror I was thinking more like Slay the Princess or DokiDoki Literature club. Visual novels that intrigue and mess with your head with less gore than you'd think.
I was going to put my response behind spoiler tags, but given I think most people know the general idea of what Doki Doki is, I think I'll be okay.
So I don't understand how people don't immediately realize what Doki Doki is when people say: "Don't look anything up about it." That is like the very definition of: "This is a creepypasta thing." Like HOW are you not instantly looking for the messed up thing that is bound to happen? What other reason has anyone EVER had to say: "Don't look things up"?
It's not scary when I'm immediately clued in like that.
Going back to me being scared. Yeah I'm not one who scares easily when it comes to video games. (I couldn't say too much to movies. I don't watch many horror ones)
There are certlain mechanics that I know bother OTHER people, but they don't get me, and in fact will often just piss me off.
Any game where you can't attack the monsters and can only hide is a slog to get through. I get no extra tension from having to 'hide' instead I get annoyed because if I could just THROW SOMETHING at the monster and run, then maybe this section wouldn't be so damn FRUSTRATING.
The best example is a game that ironically isn't a horror game. Metroid Dread had those robots that you have to go into their area and basically avoid. I hate these areas not because the 'Fill me with Dread' but because I know it's going to be an annoying dodging game where if they catch me. MAYBE I can hit the stupid counter trigger and get away.
The SA-X in Fusion was done SO MUCH BETTER because if it caught you, it just damaged the crap out of you, causing you to panic and try to get away. I made me feel I had a better chance at trying to survive, and it caused me to get worked up, when in Dread it's basically. If it catches you, you just lose. There is no getting away, you just have a loss forced down your throat. Deal with it.
This is why Fatal Frame is my favorite horror game series. Ghosts can be creepy, they do a good job of making them creepy, and in order to fight them it's better to have them come as close as possible to snap a good picture, but it pays to just fight them off, rather than have to run from every encounter.
