I'm not completely sure. I don't like the generic zombie apocalypse played completely straight; it's easy to have variations in it that can make it something that very much appeals to me, though. The whole 'rebuilding' thing is certainly different as it focuses on something entirely different than the (usually) dumb survival horror and/or mass slaughter. I was thinking of waiting to see more of how you present this based on other potential player's responses. I'll think a bit more about it, though.
