Workers and Resources: Soviet Republic is the most complex, and thus obviously the best, city builder ever made. For those who know the genre, consider the sophisticated supply chain optimisation of Factorio or Satisfactory plus the managing population demands of Banished or Surviving Mars (complete with oh-god-you-screwed-up-everyone’s-starving-to-death failure spiral) and a fair bit of the classic trains-and-logistics TTD gameplay. It doesn’t have a difficulty curve so much as a cliff, which makes the payoff of eventually getting everything working a lot like that old Dwarf Fortress comic about fun.
