Alan Wake 2
This game might be my GOTY, which is insane given the games that have come out this year. It is exactly what I wanted when they announced a sequel to Alan Wake. It captures the ideas of the original, and updates them flawlessly. Gameplay is actually good now, the shift to full-on survival horror works perfectly, the story is incredibly well-done, everything just comes together in a marvelous whole.
The game isn't perfect, obviously, but any complaints I have are minor nitpicks, overall they completely nailed it.
Grade: A+
