I would love to see this map done. I've tried 2 times with other graphics-guys, but it has never worked out.
You have a very different idea going on here, though. Neither of the other projects I was a part of used houses and hotels as part of the map. This is very interesting because now we have mandatory tags for attacking. I really hope you continue this one ManB, after all the ones you've started it'd be nice to get one in the Q-Bot!
I'd be willing to write the XML for this if needed.
