fallout3 and NV had some of the best dlc this gen
Far Cry 3 Blood Dragon deserves a shoutout
Also, most Bethesda add-ons are pretty substantial
Borderlands all the adds ons were good too.
Blood Dragon wasn't an add on, it was a stand alone experience.
But that still is DLC I guess.
New Vegas Dlc was trash... Only thing that stopped me from completing the game
