Direct2Drive has Fallout: New Vegas Digital Collector's Edition (PC) for $13 downloaded. Includes the novel All Roads, which ends right before the game starts. Step into a post-apocalyptic 1950's America as you seek revenge from the person who tried to kill you for a mysterious package.
This is a great game but far too many bugs and crashes. $13 is about right for a game they don't want to patch properly.
