I don't think Fallout 3s DLCs are all that good desu. I know people praise The Pitt as the best one and that may be true but it is almost as linear as Operation Anchorge and the issues in that area aren't that interesting. Zeta itself feels like a random encounter that blew up into a dlc and Point Lookouts enemy design is horrendous, but it at least has a neat map to explore.
