Here's an idea. How about running a contest and open it up to 1 or 2 man teams for new small NPC towns where there must be a excellent story lines and excellent drawings/modelings of the town. That way all you guys would have to do is implement it. It might work better to run it once the game is released and the editor is firing on all cylinders for the community.
When I'm not in my right mind my left gets kind of crowded.
