Sengoku Dynasty belongs in the survival crafting genre of games, like Valheim, or Palworld. It does have automation like Palworld, but of course you have villagers to do the work instead of Pokemons. From humble beginnings as a refugee stranded on a coast, you quickly get to building your first village, and can currently end up having up to 4 villages.

What I typically don't like so much about survival crafting games is the combat part, where for example raiders attack your village. Fortunately you can turn that off in Sengoku Dynasty. You need to kill some bandits as a condition to liberate some areas, but you can trivialize that by giving yourself infinite health. So the combat never gets into the way of the part I like, gathering resources and building villages. I am basically playing it more as a cozy game.

Having said that, I played Medieval Dynasty for 30 hours, Palworld for 50 hours, and will probably play Sengoku Dynasty for 30 or so hours and then stop. These games all have some sort of progression system or tech tree, and once you can build the best buildings, there isn't much reason to continue. There is also the aspect that running around in a new open world collecting resources is fun, but only for so long. Survival crafting games are also comparatively cheap, you can usually get them for around $30 or less. And if you just plan to visit for a while and leave anyway, you can get many of them for even cheaper on Game Pass, as it doesn't matter to you that you don't get to keep the game.
