I loved fallout 3, I played through it multiple times and explored every section of the map, buying each DLC day one. That was until mothership zeta, I knew I wouldn't like it and so I put it off. A few weeks ago that DLC was on sale and I finally gave in. It was an arduous journey as I had expected but now I can finally feel that I have experienced the complete unabridged fallout 3 experience. 
But I can't help but feel that I've been left with a sour taste because of that final whimper of a DLC, an awkward afterword to my favorite game and a blemish on a tour de force of DLC which proved that DLC really can improve upon a game. Anyone else feel like this or did you like mothership zeta?
