The economy

I am still thinking about this, and this is just what I came up with for now.

I want the economy in this game to actually matter, not like in other games where you can sell anything and it wont have any effect. Every faction/race will have their own bank, in which the kingdom itself stores the money. This means that every time you buy something from a vendor, your money doesn't just disappear, but goes to the king, and then can be used to make troops or buildings. Also, this works vice-versa, you can't just sell a billion items to a vendor, there is a practical limit.

I will expand the functionallity of guilds in this game, so a guild can speciallize in a certain profession,  and then make profit out of it. So if you want to make some gold so you can buy armor and weapons for your soldiers, you would join a stonemasons' guild and sell stone to people who want to buy it. A guild would probably arrange the sales for it's members, say 10 people each produced 200 units of stone, and someone bought some stone for 10 gold, everyone would get 1 gold. Of course, if they didn't do the same work, the ones that did more will get more money, obviously.

Also, when a certain amount of money is genertated by players, it will be decided what should be built next by some kind of democracy (a new military camp, a new armory, etc).
