I'm of a mind that "true" horror is increasingly impossible to square away with the reality of what it takes to make an AAA game now. The costs and time invested are so great you have to go for mass appeal, you have to intentionally go for "safe horror", copying whatever is popping off at the time like zombies or slashers, for games it's 3rd person action horror, etc.
You can't push the envelope, can't experiment, can't make people uncomfortable cause you risk pushing away that mass audience, horror that really sets our to disturb you is more domain of the indies now that AAA costs have ballooned to the stratosphere.
Movies have dealt with this, keep horror low budget and use your creativity to make a unique experience. Five Nights At Freddy's is the poster boy for this success for games.
Resident Evil might as well be to other big budget horror games what GTA is to everything else, it's gotten so big and entered public consciousness to such an extent it's become a "safe buy in" and you can't replicate it.
