I don't really know much about what it was like before the war. Lot of places are still full of radiation and broken down, though. We don't have running cars or anything, either. Vegas is still standing, but only cause House shot down most of the missiles headed that way. Most places weren't so lucky.

Ghouls weren't a thing before the war, but Charon could probably tell you more about that. Not sure about animals. Seems like a lot of the things running around the wasteland probably weren't there before, but I don't know much about pre-war animals. [As an afterthought-] We still have dogs. Normal ones, not like Rex.
