Feudal colony sim akin to Rimworld or Songs of Syx that focuses on the politics / social interrelations of feudalism.

You aren't just an omniscient ruler with perfect control over your subjects or the direction of your kingdom; you have to actually engage with establishing households, families, lineages of artisans. Your resources are taxed from the holding families rather than fully controlled, and to establish new families or improve existing ones you have to enable them to trade with each other as well as help them directly with gifts of materials.

In that respect it's particularly unique. Pretty tough to get into though, with a long tutorial that still leaves you feeling a little adrift in the main part of the game.
