Why is amnesia so awesome?

[Istrebitel]

1) There is no fighting monsters back
2) The game combines EVERY possible way to scare you. Fear or dark? Fear of monsters? Claustrophobia? Fear of bugs? Fear or mice?....
3) In some places developers VERY WELL anticipated the player's reaction. I think one of the best events so far is the room with the infamous picture...
4) Design is great. Graphics, sound, music, ui (lack of it), controls, models, textures, shader effects, everything! Alltogether its even better!
5) Maximum immersion into the game world - no need to save, no places where you replay a part over and over to get to the next level, no puzzles that make you open a walkthrough...
