Alright, I guess in Fallout 3, this happens a lot where there are a lot of abandoned buildings, even after 200 years, they were still abandoned.
New Vegas has the theme of rebuilding, which is different to Fallout 3. Why then, is the Repconn HQ frozen in time? The Fallout Wikia says nothing about any reasons why, as far as I know.
Is there an explanation of why no-one has taken charge of the building? Or was it just developed as a cool dungeon with fat lewt?
