Seems to be Dwarf Fortress inspired:

• Start with 7 dwarves but you can build and support a population of hundreds.
• A simulated world with changing weather and seasons that have a big impact on gameplay.
• Every one of your settlers has their own needs and desires to fulfil as they work together for the common good.
• A deep crafting tree that leaves no natural resource unused, tied together into satisfying production chains.
• Progress through skill tiers to craft better tools and weapons.
• Trade with merchants to increase your wealth even further.
• Form up and train your military to battle monsters and invaders…
• …or play in Peaceful Mode to chill out with a relaxing city-builder experience.
• Twitch integration (using viewer names for settlers) to encourage stream audience interaction.
• Built “Mod-first” so that everything is moddable.
