Started it last night. The character models are fucking scarily realistic. I don't think there's anything available right now that even comes remotely close. Some of the darker shots you'd think it's a video someone took of a real person.
I didn't get too much into the ghost shit as I just made it onto the ship and that's chapter 3. The game is DARK holy shit. The game starts slow, but I never feel bored with it. SMG knows how to build tension.
