Extra Punctuation: The Common Mistakes of Horror Games.
From my perspective there are some mistakes, formally known as officials, too.
1.) The attempt to legitimate the own mental disorders by being the protagonist in something declared horror, which actually isn't.
2.) The claim that one must be frightened by typical horror creatures... if they wouldn't fascinate instead of frightening, then who would buy the stuff?
3.) Repetition and Plagiarism... badly copied return of the already known in cheapest new disguise...
4.) Life. Sometimes watching a film or playing a game is only fun on 1st try, not just because low replay value but because the enticement was temporal. Once seen through it is mostly crap.
Book of Unremitting Horror was a cute discussion of a known principle... unique monsters, not another or, another vampire or such...
PC-Games: 1st chapter of FAHRENHEIT was spooky, as it touched me, thrilled me. Phantasmagoria had a unique moment for sure... Alan Wake? I saw the film in the 70's and one of the remakes... cooked up waste of time... Vampire Bloodlines, the Malkavian mansion 1st eye contact spooked me...
Compared to fantasy horror RPG is often badly made and weaker in system, which I find sad. I made a research on dark and deviant art and there are plenty of people worthy enough who get no chance in the industry because of their own way of life... It is the product which sells, not the person.
