This is easily the best storytelling in a game ever. It doesn't even feel like it's trying to mimic a movie, either. It's just...it's own thing. It's cinematic, of course, but it's more than that. More than any other cinematic game, it deeply understands and takes advantage of the medium. It could try to copy storytelling like a movie and be done with it, but ND didn't want to stop there. It's beyond anything I've ever seen.
Chapter 4 is probably the best and most emotionally resonating interactive experience I've had in all my time with games.
