There are a lot of horror game tropes I hate, like:
Jump scares
Cliche monster designs such as mutilated human, ghost woman, singing/giggling little girl, and worst of all, asylum inmate :cringe:
Having 'insanity' as a game mechanic
I also hate when horror games basically screams at you to "Be scared now!!!1!" including things like:
Player character breathing heavily when they see something you're supposed to scared of.
Camera effects such as shaky cam, blurry cam, blood on camera or 'insanity vision'.
A monster screaming in your face
A loud jumpscare music sting
Now, I know what you're thinking, "Dirt_Owl, do you even like horror games at all then?"
The answer is no. No I do not.
I think Dead Space doesn't do most of these, other than jumpscares of course. And mutilated humans but at least they get creative.
A lot of your later complaints seem to be the result of Slenderman. Horror games used to be games that were scary, now horror games have "horror mechanics."
Bioshock was pretty scary at the time, minimal jump scares. It was all in the atmosphere.
