I like my post apocalypse world to be like Mad Max, Boy and His God, etc not this science fiction stuff involving being a lab rat being experimented on. It reminds me of that alien nonsense of Mothership Zeta in F3. It doesn't look to 50's to me from what I saw and read. I would love a DLC that has that 50's feel since I'm a fan of the 50's and the Cold War.
Honest Hearts is certainly not my thing since I don't believe society would devolve into a bunch of scantly clad primates beating drums and throwing spears. Most people of civilized countries are educated and any of those survivors of the apocalypse would make use of their knowledge and use the surviving technology, housing, books, etc to their advantage.
