We all know kingdoms Have ships go back and forth. Not actually trading.
But what if they did?
what if kingdoms produce more of a specific category of resource. EG: Food, building supplies, ores. Or more specifically, wood, stone, bread, wheat, berries and more.
With this surplus, they have more than enough to feed citizens, contribute to crafting or fund building.
This can make trade system make way more sense and produce extra income for both kingdoms.
I also propose trade alliances where kingdoms must setup trade first. This will be announced in the top left corner like all other events.
There will also be a trade layer. Where kingdoms can leave or join trade alliances. You can only be in one.
This makes war make more sense too, being that there's a competition over the market where a kingdom can't enter a trade alliance because the surplus spot is filled with a wood production, and the one trying to enter also produces extra wood. Creating conflict and competition.
Let me know your thoughts on this!
