Hey, me again. Jeez, i hope i dont spam your forum to the max :D.
If its too much just tell me
Well, btt. Currency and economy. Ive seen you implemented the painting feature which is really cool What about the possibility of having either one or plenty of currencies? Like, depending if possible or not, Kindgom A mines gold and has a good stock of it. Now they decide to make their own coins. So they use a tool which allows them to "design" coins. Those coins will have a "mass" and "purity". (to have a basicvalue) Kingdom B instead only has a small goldmine but herefor a silvermine. They mix both materials into whitegold. While Coin A has a mass of 5g and a purity of 90% the value is set to (70), Coin B has a mass of 5g but just a purity of 20%. So its Value is set to (30).
Player can now use these coins to buy stuff in the nations. This could raise economy and maybe later on, different stuff will be only aviabl on specific locations. Like special ore, special animals etc.
