Dom Pedro II, does that mean that the other civ continuously hands over its money, techs etc.? Or is it more like a one-time thing, meaning you get all the money, techs etc. only once when the agreement is made?
It's continuous. But you don't get all of their money per turn.. just a percentage... a very large percentage
But, naturally, the vassal can get out of the agreement too, but canceling the agreement leaves you at war with the Lord (think of it like a rebellion).
On the other hand, there's a less severe diplomatic agreement called Protectorate that can be cancelled by the protectorate without a declaration of war. It, however, does not come with as many cool benefits for the dominant civ that the Vassalage agreement does.
The other thing present with both is that the protectorate/vassal has no direct diplomatic relations with any other civilization. It automatically assumes the relationships of the dominant civ. So if the lead civ has a war with civilization X, the vassal will too. If they make peace, the vassal is at peace with civilization X. If the lead civ has open borders, so too will the vassal with the third party.
I also want the Vassal state to donate some of its troops to the Lord civilization's armies somehow... like automatic gifting I guess. I haven't quite solidified the details, and all of it will be subject to change of course.
But yeah, basically, it provides an alternative to simple conquest.
Some of the other diplomatic states I'm considering are: Annexation/Surrender. Basically, if you're at war with a drastically inferior civilization and you're trouncing them militarily, they might accept full surrender and annexation into your empire. Basically, this destroys the civilization as a player but hands over all the cities, units, remaining gold and technologies to you. In general, it's exceptionally rare for the AI to accept this.
In the case of Vassalage and Surrender, there's a strong possibility that rebels will appear in the areas around the city to oppose the puppet state and the Lord. Essentially, these will just be tougher barbarian units that will hassle the vassal and lord alike... or heck, even the people who happen to be adjacent to them.
IF we can find a way to have a schism develop, that might also work too.. so that if Civilization X accepts Vassalage with Civilization Y, it might cause CivX to split into the puppet state of CivX and the "free" state of Civilization Z. A good example might be that of Vichy and Free France in WWII. Otherwise, it'll just be barbarian units cropping up.
Another diplomatic state I'm considering is one that can be made amongst several civilizations... In other words, rather than Civilization A having a defensive pact with Civilization B and another with Civilization C. Civilization A can create a sort of international organization that B and C can join as can Civilization D and F. And so they'll all be part of this combined agreement with similar obligations and priveleges. Sort of like NATO, Triple Entente, even the Axis.
At the moment, I'm debating whether I should create multiple organization types for this or if it should be customizable... for example, something like the GEACPS, Warsaw Pact or some of the customs unions that either existed or were planned that would've essentially made one partner the ruler over the others.... sort of reducing them to client status. On the other hand, other organizations such as the Zollverein, NAFTA or the WTO are really just economic agreeement organizations and are not political or military institutions.
So basically, the founding state of said organization could have a series of radio buttons, check boxes or sliders to determine what the organization would have control over, the extent of that control, and the status of the members as being equal partners or subservient to one state. That in turn would determine other civs' willingness to join it obviously
