Glen A. Larson, the creator of the BSG of 1978-1980, was Mormon. That show was highly influenced by Mormon theology (e.g. space lost tribes of Israel, space pioneer trek, space-Satan showing up, space eternal marriage). However, only the most basic concepts of the original show carried over to BSG of 2003-2009. That the new show had religion at all could probably be blamed on Larson, but the shape that the religious concepts took in the new show lays squarely on the shoulders of Ronald D. Moore, who "describes himself as a 'recovering Catholic' and is currently agnostic."

And as side note, why does Caprica series barely seem to match up with the 2003 BSG backstory. Because it was based on a unrelated sci-fi TV script that was reworked (or perhaps shoe-horned) to fit into the new BSG universe. That little detail seems to have become buried in history.

Get yourself a cheap version of the original Fallout 1 & 2. Should be around 20$US. And while your at it go to the fansite No Mutants Allowed look up the games projects that have the same non-linear spirit as Fallout: Arcanum, Age of Decadence, Zero Projekt.
