I agree with your entire post, but this last part could be explained by the Reds striking the DC metro area with a neutron bomb as well as a few smaller 100kiloton nukes. Magnitudes greater in radiation, but minimal damage when compared to conventional nukes.
Yes, but there are ridiculous examples like the White House, the White House is a crater, yet the buildings across the street are mostly intact. But i can see your point, that makes a little sense, but that also further begs the question, if that place is so bloody bad off, so messed up on multiple levels from many a coincidence such as this, why in the hell is anyone still living there, or better yet, why is anyone that lived there still alive?
@ The Rook, if you would rather jump to extremes like that, rather than concede anything to be wrong with Fallout 3, as i have shown there to be, maybe you should rethink your position, i have said many a time that i love Fallout 3 as a game, but it has many mistakes in the way of being a Fallout game, you need not to assume i hate the game, for i do not, but i can recognize its shortcomings and provide factual material to support my position, and it would do well for the entire discussion, and your position, if instead of attempting to undermine my position, you would bring up points that support your position, such as Rads-A-Plenty has done.
