Having a genre where my city or empire is the main character, the main sources of challenge come from the growing pains of a larger settlement and dealing with external forces of nature rather than AI "players" participating in a competitively balanced board game that can't actually play the game well so difficulty comes from giving them free stuff.
#Frostpunk remains one of my favorites, where struggling against the death spiral remains very engaging. #NewCycle is quite fun too.
