Simply the most scary survival horror ever created.
I won't tell the story. Imagine yourself fighting in Resident Evil and Silent Hill.. Now take off your shotgun, rocket launcher and lightsaber and replace it with... a camera.
A camera that requires you to be in first person view to shoot and weaken the enemies. Most of time you are walking with your heart in your hand inside a room, hears a noise and when you aim your camera to check whats going on and defend yourself you get a fricking ghost of a woman with a broken neck or pierced eyes trying to give you the "grab of death".
Fatal Frame isn't a game that kids, teenagers or even adults that have heart problems or are easily impressed with to play AT ALL. Its a game for those who can face their own fears, even if trembling, and fight it to survive.
