Fallout 3 Add-on The Pitt and Operation Anchorage

The DLC for fallout seemed to be made fast and did not even think of ways to contribute to the story but the pit. the pit is a story of freeing slaves from the oppression in the diseased area they live in where the only cure is a child, this quest is long and hard but is completely worth it at the end when you get your rewards. If you can only choose one of the DLC's to choose from i highly recommend the pit.
