Stellaris Dev Diary #247 - New Ways to Rule

Hello everyone!

In the Overlord Announcement last week we mentioned that vassalization mechanics will be undergoing some significant changes in the 3.4 “Cepheus” update. (Click here to wishlist!)

Previously in Stellaris, subjugation was rarely a more compelling option than simple conquest, and being subjugated often essentially meant a permanent decline of your empire and a “Game Over” screen in your near future. Subjects did not offer sufficient benefits nor had the freedoms necessary to be enjoyable to play.

The Scion origin from Federations was somewhat of an exception with most of the restrictions on both subjects and overlord being waived for them, but we felt that while the system was good, it could be even better. It would also be nice for the Scion to work within the rules rather than being so “special-cased”.

Some people noted that as part of the unity changes in Libra, a bit more of an argument for spinning off sectors into vassals could be made, but with the current numbers it’s generally more valuable to control those systems directly.

For today’s dev diary, I’ll start by delving deeper into the new rights and responsibilities that can appear in agreements, and some ways this makes keeping subjects more valuable.

As with all previews, numbers, text, and so on are not quite final and are still subject to change.

Negotiating Terms​


Both the overlord and subject will be able to propose alterations of the exact terms of their vassalization contract if it’s a contract with another “regular empire”. The Khan, Awakened Empires, and the like do not haggle about the terms of their minions, but are much clearer about those exact terms.

Subject contracts start with a “preset”. These are the basic subjugation types that you know from before, plus a few new ones - Vassal, Subsidiary, Tributary, Protectorate, Bulwark, and so on. Presets have a list of default terms, and can have additional unique effects tied to them, like how Protectorates gain a massive bonus to research until they catch up to their overlord.

The default terms of contract presets may have changed a bit from the old system to better fit the new. We’ve done our best to ensure that anything you can do right now with your vassals remains possible. The core Negotiation system is part of the free Cepheus update, though many of the brand new terms are part of the Overlord expansion.

Negotiable terms include things such as:
  • Can the subject be integrated?
    • As a major change from current gameplay, there are no vassalization contract presets that have integration enabled by default. It must be explicitly turned on in contract negotiations.
  • Does the subject have independent diplomacy?
    • Subjects can be given complete diplomatic freedom, none, or they can have most freedoms except are forced to vote with their overlord in the Galactic Community or Federations.
  • Can the subject expand freely?
    • Once exclusively the province of Feudal Society, now you can grant your subject the ability to freely expand. You can also bar them from expansion, or impose an Influence tithe, making them spend extra Influence (which goes to the Overlord) for the right to expand into empty systems.
    • Most presets will start with controlled expansion with the influence tithe as the default term.
  • Various subsidies from the overlord or tribute from the subject.
    • These are broken into Basic, Advanced, or Strategic resource groups, and Research.
    • The values are percentages of the production of the subject - in the proposal below, our vassal is offering 15% of their basic resource production as tribute, but is receiving a research subsidy equal to 15% of the subject’s research from the overlord.
  • Are the overlord and subject drawn into one another’s wars, and if so, which ones?
    • None, Offensive, Defensive, or Both can be selected in both directions.
    • Yes, this means that wars can be declared on subjects.
  • Can the overlord build holdings on the subject’s worlds, and if so, how many?
    • The Vassal preset has a holding limit of 1, allowing you to use some holdings without Overlord. (Though you can lower it to 0 if you need to squeeze out an extra bit of loyalty.)
    • This value is an empire-wide limit - with a holding limit of 3, you can build 3 holdings across a particular subject’s worlds, not on each of their planets.
  • Does the overlord share sensor information with their subject?

Subjugation Proposal UI

Some subject types have fixed, minimum, or maximum terms - Tributaries, Subsidiaries, and Prospectoria, for example, must always provide their overlord at least 30% of their basic resources (energy, minerals, and food) in tribute.

Part of the Tributary agreement UI

Tributaries have many locked terms.

Others can be restricted by civics or for other reasons - for example, overlords with the Feudal Society civic cannot select the Expansion Prohibited term, must join in their subject wars to some degree, and must allow their subjects some degree of diplomatic freedom.

Feudal Society civic

Different terms affect a subject’s Loyalty, and have an immediate impact as well as over time. For example, the Independent Diplomacy term grants 5 Loyalty and another +0.5 Loyalty per month. This may prove important later.

If you’re asking your subject to do something they are ideologically opposed to, those terms may cost extra loyalty, though the reverse is also true in a few cases.

Pacifists don't like being dragged into Offensive Wars

The pacifists don’t like being forced into offensive wars.

Empires can propose a change in terms with a five year cooldown at a cost of some Influence. Exact costs are still being adjusted.

Proposal from our vassal

We are feeling beneficent today, and want you to catch up to us faster, Protectorate.

How can you influence them into accepting your generous offer? Giving them a good deal is certainly helpful, and just like before, empire relations and relative power go a long way as well.

The terms themselves are heavily moddable, I look forward to seeing what some of you come up with.

The Benefits of Loyalty​

Loyalty is the “currency” used between overlord and subject, and while the Specialist empires make more use of it than regular vassals, it’s still beneficial to keep your minions loyal since it gives you more options. Loyalty is largely determined by the contract between overlord and subject, but ethical compatibility will come into play as well.

Loyal vassals will agree to more onerous terms during negotiations, and will generally support their overlord. You can also “spend” their loyalty as part of trade agreements, strong-arming them into granting you better than normal trades.

You can request a public Pledge of Loyalty to you from a loyal vassal, making them even more loyal over time.

Pledge Loyalty

Pledge Loyalty has greater effects if the subject actually likes you for some reason.

Disloyal vassals will look for ways to be free of your tyranny, seizing the chance for rebellion should you falter.

They may also swear Secret Fealty to one of your rivals in hopes that they’ll be able to follow them in an Allegiance War.

Pledge Secret Fealty

In an Allegiance War, you seek to wrest control of the vassals that have pledged Secret Fealty to you, and they will join in on the attack on their former Overlord.

Gotta Subjugate Them All​


Like herding cats, having many vassals is hard work. Constantly vying for your attention, keeping multiple subjects happy can be difficult as jealousy ruins everything. “Divided Patronage” is a modifier that reduces the loyalty of all of your vassals, and increases based on the number of vassals you have.

You can mitigate this by offering them better terms, or by taking a vassalization related civic or the Shared Destiny ascension perk.

Franchising


Shared Destiny

Overlord Holdings​

In Cepheus, we’re expanding the branch office system from MegaCorp to be more flexible.
The corporate tab on planets is being replaced with a more versatile “Holdings” tab. For now, we have corporate and overlord holdings available here, but we have more future plans for this screen.

Much like branch office buildings, holdings are built on another empire’s colonies and can provide benefits to both empires. Much like criminal syndicate branch office buildings, some holdings might be far more beneficial to one side than the other. Each particular holding is planet-unique,

Corporate overlords can build both holdings and branch offices on their subjects’ colonies.

Holdings (Ministry of Truth)

The Ministry of Truth provides two Overlord Propagandist jobs to the planet, which turn the subject’s Unity into Influence for their overlord…

Material Ministry

…While holdings like the Material Ministry are disliked by subjects as the overlord claims a portion of the planet’s production for themselves…

Aid Agency

…Still others, like the Aid Agency, are welcomed on the planet.

Splinter Hive

Hive overlords can build the most universally disliked holding (tied with one other), which takes a portion of the subject’s planet and dedicates it to a spawning complex.

We’re also adding some holdings associated with civics or origins.

Noble Chateaus

The Noble Chateaus of the Aristocratic Elite allow them to send troublemakers off to bother someone else’s planet instead of their own, much to the dismay of their hosts…

Communal Housing Outreach

…Shared Burdens empires can spread their message through Communal Housing projects. How this is received depends largely on the ethics of the subject…

Gaia Seeder Outpot

…And Gaia Seeders, who are gaining more terraforming flexibility in Cepheus as described in Dev Diary #243, can also beautify the worlds of their subjects. The subjects tend to like that - unless they’re Hydrocentric, of course.

Since there are over twenty different holdings, I’ll share some more in next week’s dev diary (including a machine specific one), and some more on social media as the Overlord reveals continue (though I’ll repost those in that week’s dev diaries as well).

It’s a very versatile system that we look forward to exploring more in the future.

The Future is Ours​


That’s long enough for today. Next week we’ll talk about the advanced form of vassalization coming in Overlord called Specialist Empires.

Also, starting with this dev diary, we’re creating video versions on the Stellaris Official YouTube Channel for those of you that prefer listening to them. Subscribe so you don’t miss them, and let us know what you think!

ok ok ok ok! this is BIG i love it. this negotiation system is EXACTLY what stellaris has need for a while.

are there plans to incorprate this philosophy out to regular diplomacy and trade deals?

i feel like this makes feudal society a really strong civic, but in a good way, in a "good if thats the empire you are building but not really otherwise" way

i have to wonder how often "alligance wars" will crop up it seems like its a pretty hard thing to pull off with the requrements and the tendancy for empires to all hate each other.

is this going to affect the way vassals are absorbed into federations? are there any interactions with hegemony and galactic emperor? (would love to see emperor get some much needed love)

is there a holding or Term that lets you maintain a millitary force in a vassals space even when a war starts? that seems like its a big important part of overlord-ing. it would be a bit pathetic if the grand fleet of the true star empire gets kicked out of their vassals space because the vassal wants to rebel.


does how threatened an empire feels about things like hostile neighbours affect how much loyalty they get or lose from the war stance? i can imagine that your overlord saying they wont come to your defence while a devouring swarm is at their front door wouldnt make you happy. and a promise to defend you from all threats isnt really worth much when you are completely isolated within the overlords space. similar for the expansion restrictions, sure if theres open space to expand into i would like them but if the only unclaimed star is across the galaxy and guarded by a leviathan then i dont care about expansion.

after nemesis i was distinctly un-hyped for future expansions. this has turned things around. i might even buy it on release, something i promised not to do.

speaking of nemesis, are there any espionage additions? i know you dont like dlc codependancies but the espionage system allows for operations to exist without nemesis.
 
Down the road, would you consider adding holdings to non-vassal interactions as well? Personally, I've always wanted more non-military ways to interact with other empires. It often feels like if I'm not at war with someone, there really isn't anything to do with them. Holdings look like they could be a really great system to expand on that kind of interaction.

You could build aid stations in poorer empires and be a benevolent Federation equivalent, build economic buildings to boost trade and wealth, or have military outposts that you could build in weaker empires to boost their defenses. Heck, there could even be an espionage interaction to try and hide negative holdings in the territory of potential enemies.

I know it's not the point of the current system. (And not to rain on the parade! This looks very cool.) But off the cuff it seems like this might be a fun mechanic to expand on.

Not sure if it's viable, but personally I think this would be very cool. It would be great to have a trade system that looks like that vassal contract screen. Then you could go in and negotiate for things like, "I give you x% of my minerals, you give me x% of your research," etc. It might make trade a much bigger deal.

But, unless I'm missing something, gaia seeders are not a megacorp civic.

Then I'll just have to mod them into one.

The groundwork for gaia seeding other empire's planets seems like a sufficient foundation -- fingers crossed!

Modding in a corporate variant of Idyllic Bloom should only be a couple of lines of script.

Will the "Divided Patronage" modifier take into account the size/power of the subjects, or only care about the number of subjects one has? Being the overlord of a one-system polity of a newly spacefaring species should be far less strenuous than keeping control of a star nation half your size.

How will the overlord features balance with federations? Specifically:

-is the intent for federations to be a partnership of equals, while vassals/protectorates are inferior?

-will an empire with vassals be able to join a federation? If so, what will be the status of the vassals?

-what will be the benefits of a federation over just vassalizing?
 
Those ideas are not bad, but they don't cover the specific problem federation-vassals currently face: once they're part of the same federation as their overlord, the independence war is impossible.

You can even exploit it: create a federation with someone, auto-add all your vassals to it, kick the other member and, after the truce ends, subjugate them.

Now you have a federation nobody can leave: they can't leave the federation due to diplomatic dependence, they can't break free from you because you're a fellow federation member. It never ends, no way out, bound to you forever.

It's funny, as long as you're not on the wrong end of this. :D

That said, the membership of the subjects to the federations should be reviewed to avoid things like that. That case you raise is totally unfair.

Being able to reduce priority for the holding jobs defeats the purpose of it imo.

As confirmed by the Devs, certain jobs (most likely the ones that the subject may not like) can't be deprioritized.

This looks very cool. A few general suggestions I have for future updates:

  • Holdings for federations
    • I'd like to see federations reworked into super-states with their own resource stockpiles and holdings that are transferred from leader to leader just as federation fleets currently are.

  • Holdings for systems
    • Allow overlord empires to benefit from subject starbases with buildings that tax naval capacity and resource output from starbases, or else allow overlords to build small stations in their subjects' space. The latter would be analogous to the Great Khan building a base in the capital of its satrapies.
    • If overlords can't gain the ability to upgrade and build ships in subject starbases, please add a way for them to do so.

  • Integrate federation and vassal mechanics with the Galactic Imperium
    • Forming the Galactic Imperium is a bit like uniting the Holy Roman Empire used to be (still is?) in EU4: it makes you weaker. You lose your federation fleet and any federation bonuses you enjoyed.
      • It would be nice to see federations persist after the Galactic Imperium is formed. Perhaps they could gain or lose cohesion as a linear function of Imperial Authority. 0 IA could give a -0 monthly cohesion and 200 IA could give -20 monthly cohesion.
      • A suite of Galactic Imperium resolutions regulating subject and federation types would also be nice.
        • For example, federations that are led by the Emperor or which include Senate members might be exempted from cohesion decay caused by high IA.
        • Certain subject contracts or federation types/bonuses could be outlawed, with the federations/subjects of the Emperor/Senators exempt. This would be an especially interesting tradeoff if Senators conferred a bonus like extra influence to the Emperor. Then there would be a reason to keep or even expand the Senate, and an inherent risk that the Emperor's inner circle would turn on the Emperor.
      • A special set of holdings for the Galactic Emperor that cost influence to maintain and hamper the ability of empires whose capitals have them to undermine Imperial Authority would make the onset of civil war a more interactive, competitive affair, especially if AI behavior was changed to prioritize undermining Imperial Authority.
        • Being Emperor should be a race to prevent a civil war, not just a roleplay-focused way to lose a bunch of federation bonuses.

  • Integrate vassal mechanics with traditions and ascension perks
    • Allow overlords to, at the cost of loyalty, dictate with tradition tree and ascension perk a subject picks next.

I have a question about Gaia Seeder Outposts. Once terraforming is finished the Outpost is presumably dismantled, and thus the Overlord will lose out on the monthly loyalty boost. Will the Overlord get a massive chunk of loyalty from their subject once terraforming is finished to compensate for the loss of monthly loyalty?

It is complex, the federations are currently considered a complete alliance or a Political Bloc as in Hoi4 instead of a multinational with different objectives depending on the type of federation as it should be. Hence the reason why we cannot be in more than one federation.
I think that all the federation membership mechanics should be rebuilt. Answering your question, it will always be more beneficial for you to have a vassal instead of a federation, the difference is that the latter is easier to maintain and to achieve by less aggressive means. Currently it is possible for an empire with vassals to join a federation, hence the problem. The Hegemonic federation could instead become a good mix of these two mechanics (if the inconsistencies are corrected) by automatically making the member states their vassals.
 
I wonder how military takeovers will work in that system, as there is little "negotiation", as one side can mostly dictate the terms.
i imagine it would either generatea wargoal to enforce the terms when they decline like the current system. or being victorious in a subjugation war would give you a bunch of loyalty to spend.
i feel like there isnt a great solution. the first lets you impose the harshest of conditions with near impunity if you are sufficeintly strong and the second might lack a certain bite when you are strong and ruthless. things like colossus projects should have an impact.
