Yeah man, I tried the map.. It was awesome! The attention to detail is what realy struck me, it actually looked like a destroyed city.. not with weirdly well kept roads you tend to see in other maps :p I tried it in Arma 3 as well, and with the new lighting engine it looked really immersive! But like you said yourself, to really do it justice, this should be a propper addon map. Good luck with further development :)
