During those 200 years people in DC don't just fail to rebuild civilization. They even fail to get rid of the random pre-war garbage inside their own homes!
New Vegas (which starts in 2281) is better but still way too post-apocalyptic. I want my Fallouts to be post-apocalyptic but they should have been set much sooner after the war (maybe 70 years, just long enough that almost no one who remembers the pre-war world is left) and even then settled people shouldn't live in shacks.
That is funny. 200 years is a long-ass time to build a civilization. America was rocking it within like 50. Although if I remember there is talk in some of the games about some very large empires that had risen and fallen in the last 200 years.
