I think it would be really cool if you guys added a multiplayer section of the game. That it is up to 4-6 players against eachother and you could go and play with up to 1 friend so you could like team up against the others in a big map that would be random every time. So then we come to the buildings it should be all the normal buildings just that you add in the military settelments more soliders so you could choose like horsemens,Swordmens,Spearmens and archers,crossbow.
Then the Mining settelment should be important for your gameplay with that you could use the stones to build up walls around your town and get resources from the mines so you could use iron in a blacksmith so you could afford to get swords and spears.
Now the water you should be available to trade with eachother with ships. You should also be available to get troops in attack ships and cannon ships.

I think this idea would also help increasing the players of the game.
And i would be so happy if you added this to your game. So Plis try to make it possible <3
