So this is usually a taboo subject, but out of curiosity, is there ANYTHING at all you'd like to see from Skyrim or any of the other TES games carried over into Fallout?
For example, I wouldn't be opposed to marriage (which actually was started by Fallout 2), construction of your own house (albeit it would be a motley of wreckage and scrap metal anyways) and having the ability to read full-fledged books (so all the unique skill books you pick up could actually have a story or valuable information vested in them). Sprint, need I say more.
Note that this doesn't make Fallout more like Skyrim, it just makes it a better game IMO. Horses, magic, and whimsical bull can stay far away from the Fallout universe.
