Any difficult city builders to recommend?
Summer break is here and I'm looking for a new city builder to play. I like those city builders that are very difficult and has a steep learning curve. I am also trying to avoid games who are still in early access.
Previously I have enjoyed Workers and Resources, Banished, Rim World, Tropico series, Factorio, Prison Architect, Cities Skylines 1 and SimCity 4
I have not enjoyed Anno 1800 or Railway Empire
Edit: I do not like story based city builders like Frostpunk because I feel they lack replayability. Pure difficult sandbox is best.
Edit 2: Alot of good suggestions, thank you! I will consider them all and pick some based on which ones are most on sale.
Edit 3: I went with Against the Storm and I love it !!!
