Absolutely capital!
As soon as my re-animated Pulp Aegypt project has been finished (I only need to paint one mini, sand the base of 7 mummies, and paint some encounter markers, plan the layout of the hidden temple and make som floor plans for it) I'll have to turn my attention to modern/NF/ZA/PA again. Lots of potential for Fallout-like junkyards (paint the wrecks all rusty), and slagtowns...
Maybe I should see if I can find the Mad Max movies (never watched any of them.....)?
