Stellaris Dev Diary #19 - Diplomacy & Trade

Greetings!

Today our humble offering covers some of the possible Diplomatic Actions and Trade Deals that can occur between Empires. As most of you may know, the basic diplomatic model used in our previous games work quite well and we will use something similar in Stellaris. All Empires will have opinions of all other known Empires, and different actions, events and internal politics will often affect that opinion. The ethics of each Empire will of course play a heavy role here, as pacifist Empires will react quite differently to aggressive wars than would a xenophobic militarist one.

In Stellaris trade between Empires is a very direct affair. Players can create two-way deals lasting a set amount of time, and our ambition is that most diplomatic actions should be available here as tradeable objects. For example, you can offer another Empire a monthly payment of Minerals in exchange for Military Access and updated Star Charts for a period of 5 years, or receive a vital supply of the rare Garanthium resource by offering a nonaggression treaty as well as a guarantee of independence should the other Empire feel threatened. If you want to simply gift or demand something you can leave one side of the trade-deal blank, and the AI will react accordingly.

However, these kinds of trade deals will only happen between equal Empires and as most rulers know, it is better to gain something without having to give up something else. This is where more static diplomatic relationships come into play.

Tributary
A Tributary is forced to pay a set amount of their income to their Overlord each month and is most often established as the result of a lost war. The Overlord will not automatically defend them in wars, so the Tributary is caught in quite an unfortunate position until they have the military strength to either demand an end to their servitude or declare a war of independence.

Protectorate
A Protectorate is a subject protected by a (to them) technologically superior Empire. The Protectorate gains a major research-bonus to all technologies that their Overlord has already researched, and is automatically converted to a Vassal when having progressed far enough technologically.
Any pre-FTL species that is technologically enlightened is automatically created as a Protectorate under whichever Empire granted them the ability to space-travel. The Overlord in turn gains political Influence each month and the eternal gratitude of a bright-eyed new member of the galactic community.

Vassal
A Vassal is the most controlled type of subject-Empire. They will automatically join their Overlord’s wars, aggressive and defensive, and they have no autonomy when it comes to foreign policy or diplomatic relations. A vassal also run the risk of a full diplomatic integration by their Overlord.

Subject-actions
All types of subjects have a Liberty Desire expressing how content they are living under their Overlord’s rule. If a subject's Liberty Desire becomes very high they have a chance to start a war for independence, often waiting for an opportunity when they sense weakness (a taxing war, a larger uprising, a galactic crisis etc.). The Liberty Desire is a compound of a few different parameters but the main ones are the subjects opinion of the Overlord, the total military strength of all the subjects relative to the Overlord as well as if the subject can find someone who supports their cause.
As you would expect from our other games you are able to support the independence of another Empire’s vassal. Doing this will greatly increase their Liberty Desire (assuming the supporter has a fleet rivaling their Overlord) and may cause them to rebel. If they do, the Empire supporting them automatically joins their war for independence. You are also able to guarantee the independence of a smaller Empire, automatically entering the war on their side should they be attacked.

We’ve also added another vital diplomatic action to ensure that we can realistically model the complicated diplomatic interactions going on between advanced nations; the insult. Make sure to clearly express your feelings towards your enemy by insulting them, instantly lowering the opinion between your Empires greatly.

That was all for this week. Next dev diary will be written by Doomdark, expanding further upon War & Peace.

Also, can we be a subject of another empire too, or is the game lost then? It would be nice to organise an uprising within another empire, maybe even uniting other subject species against the invasors.

A player can be a Vassal to another Empire (human or AI) and still play. If the player is integrated/diplo-annexed the game is lost however.

Could we conceivably buy planets/star system later on?

We'll see. It might be that we allow players to buy/sell planets between each other but restrict the AI from doing so, as the AI often has a hard time evaluating the value of such deals.

Every Dev diary has excited me immensely... Until this one.

(And it started so well with diplomatic agreements being a 'tradeable resource' - this should be in EU4. Nations with valuable resources could use them to 'buy' protection.)

Still it's 2016 - how many protectorates, vassals or tributaries do you see nowadays?

Is there no more sophisticated way to represent the balance of power than pre-industrial terms?

Can vassals expand in some way (after uplifting) or are they diplomatically tied to their overlord like in EU4?

Will there be an option to designate a target system or planet for allies or vassals to attack?
If so, what will the options be? Bombard, ambush, invade, engage patrols etc?
 
Will there also be diplo slots like in EU4?

Is technology tradable? I sure hope not, that's usually the most abusable mechanic in 4X.

Yes and no. Old technology transfer is certainly OPed and heavily abused, but there are interesting alternative systems, like civ 5 research treaties (pay money and you and a friendly empire get a research boost on the long term) or fallen enchantress (?) system where whenever you research a technology in one field, you get abstracted points in that field. Then you can trade those points to other empires; so if I'm a militaristic empire, I can help in military teching an empire that is more focused on civilian technologies while he can offer me something unrelated to technologies or civilian technology points.

Relations between different species and multi-species empires that are spread across many star systems will probably take a very different form than the contemporary situation between nation-states on a single planet. Probably neither the "EU-style" or "contemporary style" is a realistic model of how things would work. Yet we probably want to stick with some model that people can at least understand. EU-style diplomacy is at least a field-tested model of a middle-ground between "anything goes" and a modern era where empire-building is rather frowned upon.

I know Liberty Desire is a great concept lifted out of EUIV, and mechanically seems like it should work very well here. In the context of Stellaris, however, would it be better to contemplate renaming it something a little more general ("Autonomy Desire," or "Independence Desire," or something like that)? After all, it isn't like the militarist arachnid hive cluster of Alpha Orion 7 has stumbled upon the writings of Locke and Paine and are suddenly yearning to cast off the shackles of tyranny in favor of enlightenment liberalism. They just want to call their own shots and stoping having to ask permission before devouring their neighbors and laying eggs in their leftover husks.

insult ideas for fungoid:
"You seem to have much room in your side of the galaxy for hostile takeover."
"Your mother should have fried you."
"As much as I am a fungi, my people are more into mushroom clouds. "
"Break the mold. Mass ritual specicide is always an option."
"I get a sporangium thinking of your people's destruction."
"Your mother was a spore hungry imperfection."
"your whole style is fungazi."
"We will enjoy molding you into our empire."
"your species seem game for species change."
"Will it be plasmogamy or plasma?"
"Oo...my...set on defiance are we? You will see the blight!"

Excellent DD!

Just because we don't see nations using these terms, doesn't mean they don't exist in a real way. What we have today are economic dominance and subservience, without such messy terms as "vassal".

Is there a place for actual trade or rather "Civilian trade" between Empires and inside Empire in "Stellaris"?
Trade centres? Trade-flow mechanics? Trade-ish type of government?
Commerce Empires that rule by power of Energy Credits - sounds tasty.

Many of the US territories have fewer rights but still serve in the armed forces like Puerto Rico or American Somoa. I would say this is a similar situation to a vassal.

I believe there were quite a lot of satelites even during the industrial era. Then maybe the idea of new species would bring back the idea of some beings being superior than others, so I'm not sure it's that absurd to consider vassals outdated.

A good alternative for a mechanic to limit vassal numbers would be a feedback loop. The more vassals you have the higher all of their liberty desires, with vassal of above or below a certain desire adding extra draws to liberty desire in that direction.
