Also, yes, every world except Strangerville will have this new ecological system. Because of the things that happen in Strangerville during the storyline, it just wasn't compatible. And the pre-City Living worlds will have the neighborhoods clearly defined now- the original 2 worlds always had the cheap area, mid-range area, expensive area, and business district. Now they'll have icons for them and outlines on the world map, and will have the separate handling for the eco status.
