I can see it getting old, fast. You're literally stuck in a seat and flicking through cameras so fast that it's less about building tension and more about managing a single resource and memorizing limited AI patterns.

Even that Slender game was more effective, and you're literally just trying to pick the most efficient course and manage stamina trying to find 8 pages, especially after page 4 where you lose if you slow down for more than a couple seconds. Games become less scary when you're frantically picking your way through the systems instead of immersing yourself in them. So far, the first Amnesia was the only game I've played that scared me because it forced me to navigate dark areas to find an escape with a single patrolling monster while forcing me to find light sources to keep me sane at the risk of the monster finding me. The sequel wasn't nearly as scary because there was no managing fuel or sanity, and in the first game, looking at the monster drew fit to you and made your sanity slip super quickly. It wasn't a hard game, but it understood how to balance game mechanics so it wasn't hard, but you were focused entirely doing what you're supposed to; face the horror.
