I finished it in a weekend rental I remember. It wasn't very meaty at all, or that memorable unfortunately. (Although I can still hum parts of the "It's bad luck to be you" tune…) Hunted on the other hand, took a little longer…had some old school inklings in the dungeon design here and there, but wasn't overly 'hardcore'.

That all said, this is a really fascinating concept. As a Fallout fan and radiated devourer of post-apocalyptica, I'd love to see it happen. Like Dhruin said though, it's hard not to be skeptical and doubt in the face of a lack of convincing evidence in the affirmative up to this point.
