The flag has 12 stars (with one big one in the middle), it's somewhat similar to the Betsy Ross 13 star flag http://www.gamesas.com/index.php?act=findpost&pid=0. Was there some merging or loss of states? We can assume at the point that the Fallout universe breaks away from the real world, they were using the 48 star version (http://www.gamesas.com/index.php?act=findpost&pid=0), and we would assume that Alaska, at least, joined the union, so how'd we end up at 13 stars?
