When I think of a RingWorld, I think of a giant structure built with the sole purpose of housing as many people as possible, probably a solution to overpopulation.
That would mean there is less mountains and valleys, and more space to build!

In an attempt to bring that idea into Stellaris, I set out to make a tileset and environment mod to change the way RingWorlds look on the surface.
In doing so, I decided to also create a new city-set to go long with it. Probably multiple!

Due to the nature of planet class categorization, which determines what tiles and portraits to use for each planet, my initial mod is not compatable with any other that does the same thing. The base mod is compatable with Alternative Tilesets (2.0), but for other mods, such as Planetary Diversity, I make compatability patches. Do note that if a compatability patch is used, it will break compatability with Alternative Tilesets.
Only one compatability can be chosen!
