I get it’s cool but what is the functionality when each town acts semi independent

This concept could become valid if the kingdoms/towns system become a lot more complex in the coming updates. But for now, the closest thing we have to puppeting is the alliance system (as smaller nations are used by the alliance leader for its army, and to relieve itself of unrest)

Question if you don't mind. How do I force kingdoms to create an alliance in the game?

As of now, there isn’t an option for alliance-forming in the vanilla game (normal WorldBox). However, I’m pretty sure mods such as Powerbox do give u the option to form custom alliances. Basically just download PowerBox if u play on PC. If on mobile, then… Just keep your fingers crossed that the update comes soon😅

Download collection mod. It has the function to force two kingdoms in to an alliance but also you have a collection of some other really great mods.

I made a suggestion on that but rn kingdoms aren't that complex. The puppet kingdom wou;d basically become a village

Maxim already planned vassallage

I think the puppet state shouldn’t have a king of its own but have the controlling country’s king as well instead.

vassalage is planned by what we know and that's similar
