Citizens: Far Lands

https://store.steampowered.com/app/2310630/Citizens_On_Mars/

Citizens is a turn-based hybrid of a city builder and strategic puzzler where you create beautiful cities, manage resources, plan long term investments, trade with foreign civilisations and look after your subjects. Explore beautiful islands, deal with difficult problems, and think about your next move very carefully, for it could be your undoing!

Citizens offers:

• New approach to city-building games
• Three campaigns with challenging quests and varying difficulty levels
• Over 50 buildings spread over numerous production chains
• Over 30 different resources to extract, process and manufacture
• Mechanics to spice up your experience such as plagues, fires and winters
• Combat and Trade
• Endless fun with random level generation

Meet various civilisations along the way. Sightsee ancient temples, trade with scattered outposts, and defend yourself from plunderous Vikings! Be mindful... Ravaging barbarians are not your only enemies. Fire and Plague can be dangerous too.

With all this doom and gloom above, just keep in mind one thing...

If all you want is a peaceful and soothing experience, then try out Free-Build mode! Place buildings without any restrictions on a randomly generated island, or try out economy mode for something more challenging: that's where anything can happen! You'll never run out of new lands to explore. Something will always be different.
