Stellaris Dev Diary #20 - War & Peace

Hello everyone!

For today’s dev diary, I thought I’d talk about a crucial part of Stellaris; waging wars and making peace, because as you know, not all ETs are nice... The system is different from most strategy games out there, but should be familiar to anyone who has played a Paradox Development Studio title. In fact, it is probably most reminiscent of how these things work in the Europa Universalis games.

Let’s start at the beginning. When you declare war in Stellaris, you have to state what your aims are; what the war is actually about. You simply choose from a list of possible goals, where each one is listed with a certain cost. The total cost of your picked goals cannot exceed 100. If you have a good reason to take something, the cost will be reduced. This might be the case if, for example, members of your founding species happen to live on a planet, or if it has previously been a part of your empire.

If you are a member of an alliance, the other members will need approve your list of selected goals before you can actually start the war. This is of course more likely if you are not too greedy and want to take everything yourself. That is, you will probably want to assign some goals to other alliance members to get them to approve the war.

When a war has been declared, the defending side is allowed to add war goals in the same manner, but they have an important advantage; they have a one-year grace period, and can thus choose targets depending on how the war is already progressing.

You need to gain “war score” in order to win, just like in our other games (-100 to 100.) At any time, you can negotiate for peace by selecting specific goals from your own list or that of the other side, very much like in Europa Universalis (except that you are limited to the stated war goals.)

Of course, wars are not always waged simply to seize territory: Other valid goals could be vassalization, for example, or securing a treaty of some kind. Sometimes, you might not really care about your stated goals at all, but just going in there and destroying the enemy’s space ports and stations...

Like in most of our games, occupying a planet with your armies does not mean it immediately becomes yours, of course; you need to demand it in the peace talks. There is a notable exception to this rule though; so called “first contact wars”. Before you have established communications with another civilization, it is possible to simply attack them and even take one of their planets (but once you take a planet, communications are immediately established.) Of course, such early hostility will never be forgotten, and will sour your relations for the rest of the game… There are other exceptions to how wars are waged, in the form of special types of civilizations, but that will have to wait for another dev diary.

That’s all for this week folks, stay tuned next week for “Administrative Sectors”!

I hope at 100 war score, that's simply the score at which one can do a complete take-over of an entire empire, and starting such a take-over wars is always an option.

Being limited by war goals to chipping away only x provinces in y years was a very annoying grind of a mechanic in older games. Slowing down player success by a factor of y/x is not making a game any better. Let me expand, progress, conquer, and let me have multiple options to fully deal with any and all problems that might entail.
I disagree strongly, it takes more than one war going well by chance to subdue another empire fully.

Nice DD
Is there any way to encourage your species to migrate into your enemies territory to get a CB?
Also I like the negotiate for peace indicator.

So you don't have the EU4 problem that its too expensive to take enemy territory in a defensive war, so whether you are the attacker or defender doesn't make a difference in the costs of the peace deal?

I always found it weird that its more costly to demand something from your enemy when they are the original attacker.

I am not sure how i feel about the limit on war goals.

On the one hand, when i last played endless space i reached a point where i had destroyed an enemy's fleet so i just steam rollered their whole empire taking over everything, then it was a case of rinse repeat against all other empires. it ended up being an easy galactic victory...

but if I'm honest it was not that satisfying, if there was a way to stop my onslaught it might have given the opposition a chance to get it together enough for it to be a challenge.

I think what i want is the option to steam roller an enemy but for there to be reasons why i might not want to. eg a massive war expansion issue leading to civil unrest or all the other empires really really not liking me for a very long time.

In the end i am going to place my faith in you guys because i would rather have an interesting game than one which is easy to "win".

Oh and its my 40th birthday next friday (19th) so if yo could release the game for me that would be super.
Thanks

Hey Paradox, what are the chances that we could negotiate a neutral zone? A stretch of space acting as a buffer between empires?

And further to that, if a planet exhances hands in a border dispute, is there a chance that same planet under new rule would lead to it's population becoming separatists and even terrorists?

Basically I'm thinking of the dynamic between the Cardassians and Maquis from TNG & DS9. I think it'd be fantastic to have to negotiate a neutral zone and the like, and having to handle fringe factions at the edges of your territory!

Aww... looks like I can't do genocide type wars... ie, destroy the whole species/empire in a single war that could take decades. (And of course, repopulate the planets that remain habitable with my race ofc.)
Well, might as well start to learn modding and do that myself then.

1. What is this "one-year grace period"? An armistice?
2. Choose targets? What targets?
1. Grace period seems to be the time period in which you can add your own wargoals at will, as the defender.
2. The wargoals, I imagine. What you aim to accomplish in the war.

If I may, have you considered a 'Great War' mechanic? I.e. when a war meets certain conditions unconditional surrender and dismantlement/extermination become options. I think it would be good to have these kinds of space opera style great galactic wars in the late game.

Also, is it possible to declare a normal war immediately following a First Contact War? If the aggressor takes a planet in an FC war, can the other power attack immediately after communications are established so they can retake their lost world?

I know, but to be fair, an interstellar empire would be able to call this form of client state what the hell it wants ^^ But different terms for these states depending on your empire would add a nice flavour too. Our hive queen demands thee homage unworthy vassal!

To be even more fair, they're aliens. They don't speak English. They don't speak a language that has any relationship whatsoever to English. They almost certainly speak a language that is virtually untranslatable into English because their culture and psychological makeup are completely alien. And some of them might not even have a spoken language in the first place.

So the game can use whatever English words it feels like, so long as it communicates the meaning to the player.

I disagree!
Did you realize Paradox games are not the "rush and win" type of games?
I wanna spend my time and manage the empire and win slowly against the competitive AI. I wanna feel the empire is growing and growing slowly.
I don't wanna win or lose fast because of a stupid mechanic.

If your policies allow full orbital bombardment, it is possible to severely damage planets, but not to completely depopulate them.
but can we destroy them?

Say if I want one planet from a peace deal but decide I wanna destroy every other star system they own while I'm at it

Can I destroy planets?

If I understand correctly.. The wars here are seem more limited than in EU4.. You can't declare for one thing and then take another, which seems like a shame if circumstances change wildly in the years of conflict or to war goes unexpectedly well!
