Morrowing/Skyrim
Morrowind was always my favorite Elder Scrolls Soundtrack, so you can imagine how much fun I was having when it turned out that Skyrim's soundtrack was all re-done versions of Morrowind's soundtrack! Some might say that they could have done better, but fuck them. I don't want another Oblivion Pirates of the Niben soundtrack (because it reminds me of Pirates of the Caribbean... And in Cyrodil, there's that Niben Bay in just south of the Imperial... Never mind...). I liked it, sure, but I just liked Morrowind's/Skyrim's a lot more!
Also, Saint's Row the Third. I love a game with a soundtrack featuring tracks by Deadmau5, Marilyn Manson, The Black Dahlia Murder, Amon Amarth, Dethklok, the ATHF theme, Mozart, and... Dammit, who did Blue Danube? That guy. I feel that my epic drive-by fests are made all the classier when an 18th century Waltz is playing over the radio.
