At the moment I'm using zsh with powerlevel10k. But powerlevel10k is not really supported anymore, and seems to be basically on life support. While it still works for now, I have been thinking of switching over to fish. But the lack of posix compatibility is holding me back a bit.
I really love Anno for this, 1800 is the only one I have played and I think it's an amazing game. The base game on its own has tons of content already but the dlc's add whole new regions and lots of supply chians to the game. It's a bit of a crossover between a city builder and a supply chain simulator, where the majority of the game is based on providing the needs for your residents. It's on sale very often, including the dlc's.
If you were to get it, I recommend getting the dlc's, maybe after a playthrough of the base game. If you wanna know what dlc's to get, you can check out these videos:
