Here is my idea that should be added to civ
Professional Army and Black Market
Some civics should be edited as some of them should allow Professional army and Black market.
For ex; pacifiscm doesnt allow two options while police state should allow only professional army. Only slavery allows non-military unit trade (workers, scouts and explorers).
Professional Army: civilizations are allowed to buy or sell military units via trade negotiations. A civ can want/offer units (with or w/o experience point) for some money.
for ex; a civ wants from you "two axeman with at least 2 ex points for 10 gold before 3 turns end". you can accept or negotiate if you want. "before 3 turn end" option allows you build/draft units if you dont have any in your hands at that time.
once you buy the units, you will be allowed to re-select unit upgrades (if units have enough ex points) as you desire. Units will be labeled as professional army and those units have higher maintaince cost than build/drafted units. As they level up their maintainance cost will become higher (slightly).
Black Market: a global market where civs can put units with selling option, so other civs can start negotiations. Since it is a black market none of the civs will be able to see who is vendor and who is customer. Diplomacy has no effect here.
if you change to a civic that doesnt allow professional army, your pro. army units will join to black market and other civs will be allowed to buy those units with 1/3 of your buy-price. if you stop using slavery, your non-military units will join to black market and other civs will be allowed to buy those units with 1/3 of your buy-price. once your pro army joined to black market, even if you re-arrange your civics you wont be allowed to buy those units 1/3 price but allowed to buy with your old/first buying price.
you can have units which you cannot build/draft because you didnt get the necessary science yet.
