Westerns are great, yeah.
I think urban environments are beautiful. Fallout 3 has a great atmosphere and aesthetic. The pitt is awesome. One of my fave post apoc books, pic related, has a sequence where survivors in a nuked nyc are trying to escape, and it makes good use of the subway and tunnels. It's just cool.
Swampy bog areas and islands are also fun-- point lookout, far harbor.
Foresty areas have potential too depending on what you put in them. Neoscavenger was interesting. 70% forest. 20% cities. 10% agent orange swamp. There's a native tribe, old military installations, weird cryptid shit, and a megacity. It takes place in michigan, something you don't really expect.

Yeah idk why they chose that of all places. I don't think they even made good use of the area. I mean it's been so many years in universe that I think you could really make up whatever environment you want and then just call it texas or kansas or any state.
