I’d be nice if there were an epicenter of some sort, where New England is more nethered than elsewhere. Could tell how hot or cold you were to finding it by the sort of map that gets genned (could be a good use for the desert_test stuff)
On that note. What if each new ‘chunk’ of world map genned from going too far north/south/west/east genned via different rules? Like a nuked out area with high background radiation populated by extra large mutated wildlife. Or an ‘Anomalous Sea’ That’s mostly shallow/deep water and sea life.
