Great storytelling and immersion.
This is a first-person exploration-based mystery-adventure game. It is relatively short and could probably be beaten in 3-4 hours. I took 5, since I spent a lot of time walking around and taking in the scenery. Cranked up to max settings, the world in this game looks incredible. I am literally using screenshots I took as my desktop backgrounds.

I highly recommend picking this up when it goes on sale.
