Well, I think Bears live in Slovakia, so we might have to deal with Yao Guais later on (Hungary is right next door, and I live pretty close to the border). Plenty of water in the country (underwater sources too, no worry about radiation poisoning) and it's pretty easy to find some basic firearms. Kalashnikovs, too. But it isn't really Fallout if it isn't America, right? It'd probably be more like STALKER. (plenty soviet-era architecture, too)
...now that I think about it, that is a far, far worse alternative. Dear god. We are so fucked.
