I feel as though you've either already bought it or downloaded the demo, or something, but I'm going to add my two cents in at the end of this.Hound174 said:snip
I didn't find Amnesia scary at all. I was really disappointed with how everyone hyped it up as being the scariest thing in the world. The main problem is that all of the monsters despawn if you wait long enough. There were only 2 that I counted that did not despawn, and you could make one of those despawn by traveling far enough away from it that it disappeared. This was really depressing. It meant that you never really had to deal with monsters. As soon as you heard it spawn, you could find a door, close it behind you, hide in the corner, and wait until the "monster music" died down. NOT scary.
I don't want to spoil any of this, but even the infamous water monster was boring. Examination of the level design often removed a lot of the tension and told you that monsters were coming/about to come.
That being said, I enjoyed Amnesia's narrative and world building. Atmospherically I think it was pretty great, but the scariness/monsters were a bit of a disappointment, and I hope they sort that out for the new one.
