I wanted to play RimWorld on a real Earth map, so I built it over the course of a few days with Claude's help. RimEarth adds an “Earth” checkbox to the world generator. Tick the "Earth" checkbox and generate a 100% globe, and the map becomes Earth far into the future.

Over 400 ruined cities appear as colony maps, and I tried to get the local character of a place right, but the globe is a big place. If you see something obviously wrong, let me know here or in the workshop comments.

Tested with base game and Odyssey.
