This game is unique. Some points I tuck years to understand and I still find new aspects.
The look in the mirror at the beginning is a classic scene, and a unusual canon scene for a game. You see, if you delete this scene, you change the entire story, it becomes a RE story. It is not just a dramatic scene like The Last of Us because it will remains during all the playtrhough of the game pointing that there is more than all of this you can see, and is deep inside of you the key. Plus, the interesting part is: as long the monsters came from James, this reality is confronted by the interaction with other people that, obviously, does not follow his hellish logic. The dialogs show a different true that Pyramid Head try to guard away from James. And there is still Maria, an element that is and is not from James, also a character hard to find!
I really don't know another game with so complex narrative.
