Honorable Mentions:
Payday 2
While the base game came out last year, Payday 2 has been getting more DLC than most games do, at a pretty regular rate as well. Great if you were looking to prolong the game, but purchase wasn't even necessary for some, and new heists only required ownership to host. Simon Viklund continues to put out awesome, pulse-pounding tracks to help set the mood whenever your heist goes loud. The same trick of making the music rise and fall with the action has yet to get old, and can still give you a tactical edge in game, letting your crew prep when things are about to get dicey. Another nice addition was the music selector in game, so if Evil Eye just won't stop playing in your head, or you want to pick something from Payday 1, you've got the option.
