That's why I liked Amnesia. It has far fewer cheap pop scares than a lot of bad horror games, and mainly relies on its atmosphere to keep things going.
I legitimately did not find Amnesia scary when watching LPs of it. But there's something distinctly different when you play it for yourself, without a quirky Canadian guy babbling in your ear the whole time. Even just seeing the first enemy in the game standing 20 yards away looking away from me was enough to send me into a panic, because the atmosphere built up to that one moment gradually for what must have been close to an hour.....but it's not a traditional release. Instead of building up to a sudden reveal, it builds up and maintains a high tension for ages and ensures that nothing actually threatening happens. When the first enemy shows up, there's no dramatic chord as you open the door and he doesn't leap from a closet directly in your face. You just open a door and start to head out and he's standing there off in the distance like he was always there. It's legitimately surprising, because there's no way to predict it happening and it's not a cheap jump scare.
