After Thief, Lords of Shadow 2 was exactly what I needed. Thief does dark and gothic in the most dreary, boring, dull-as-dishwater way possible, and LoS2 just blows it out of the water in terms of art direction, music and narrative.
It was like being fed un-flavored tofu for weeks, and then somebody hands me a slice of pizza. I'm all like mmm! I love pizza. And I still love video games!
