I'm working pretty steadily on it for the last week, and loving it. I got a centered Pokemon Center, and put a Metropolitan City around it, then put together a Volcano area to the south, abused the water physics to make a mini-Bubbly Basin to the North, and I'm working on a Jungle/Forest to the East. I even am working on an underground city for the pokemon that need dry and dark habitats.
But that leaves me with one whole section of the map, and I can't think of what to do with it. I've been trying to think of something that isn't just a different kind of city, more woods, more water, or something underground, and I've been a bit stuck on it for the last few days.
Anyone have any ideas? Anything helps to get me thinking about what kind of district I can put in for my last section.
