Fallout 3 Hands On

"We get anal about which buildings should be in Washington DC, with giant piles of books on architecture on DC and we ask what year buildings were made. 1955? It’s out – it wouldn’t have been in this universe."

So the Bethesda studios, mentioned in other previews as a place you can explore, must have been created pre-1955s... or this is a complete and utter lie...

Yeah, there is a Bethesda building in there, but I'd treat that as a mere Easter egg more than anything else. ;)
