One of the things that I think should really be considered is adding more models to the surface of Kerbin. I know it sounds ambitious to add cities/towns to Kerbin but I think it could be done without causing to much lag or messing with the existing terrain. Cities could simply be collections of skyscraper models sitting in flat locations. Towns could be collections of house models. Having actual Kerbals walking around in them is probably an unrealistic suggestion, but that would be awesome. In linking the cities could be simple roads. Probably the coolest aspect of these cities would be if they lit up at night and where visible from space. Overall I think this would make Kerbin seem like a much more vibrant and living place. Sorry if this has been suggested before, I just wanted to provide my take on it.
