And how Fallout is that? Let's see. Every square has been renamed, of course. The board has been entirely customised ("free parking" replaced with Fallout 3's "please stand by" screen, for example). The community chest and chance cards have been replaced by perks. The pieces have been "rusted" to give them that post-apocalyptic look. There's even Nuka Cola caps that can be used as money.
About the only complaint I could make is that it appears to have all its houses, pieces and dice. It's hard enough keeping track of all that crap in these peaceful times of ours, so Lord only knows how they all survived the apocalypse!
