Regardless of how some may think about the very concept of DLC, what are some of your favorites?

I myself am usually not very enthusiastic about it cause I stand by the idea a game should be complete once it's released and DLC is usually just a money grab; but even I have to admit that FROM Software's Artorias of the Abyss and The Old Hunter's DLC are fantastic and still prime examples of what DLC should be like.
