Welcome to another Europa Universalis IV development diary – Number 23 in fact. We have already done three more development diaries than we’d done for Europa Universalis III, and we still have about 30 more possible diaries to write.* There is still a lot to talk about when it comes to diplomacy, naval combat, westernization, economy, the Reformation and more.* And yes, we also need to make country guides for Poland and Norway.
Today, however, we’re talking a little more about diplomacy, where we introduce a new concept, and talk about how a few others have changed.
Coalitions
Sometimes you simply do not want to ally with someone because they are likely to drag you into a bunch of wars that you have no interest in, but, at the same time you think they would make a great ally for the war you do want to wage.
EUIV addresses this problem with the coalition system, a mutual alliance that is directed against a single country. You have an alliance leader, say the Papacy, who organizes an alliance say directed against Venice. Then they sign up countries like France, Milan and Austria. The alliance only fires in the event of war with Venice but if war does erupt all countries in the Coalition will be called in.
Initially, this power is only open to Catholic countries and can only be organized by the Papal Controller, reinforcing the idea that the Pope is still quite important in the early centuries of the game. Later on though, advances in diplomatic technology will allow any country to organize its own coalition against a common rival. Some Dynamic Historical Events can form some historic coalitions if the stars are aligned properly, as well.
Coalitions become, then, a great way to contain a growing threat or hated neighbor since everyone signs on to fight before the war starts. It can be challenging to get a coalition moving, since you need your potential allies to see the strategic threats in the same way you do. But it is a valuable tool that reinforces common interests.
Relations
We talked earlier about the change from bilateral relations to a system where you can hate me, but I don't hate you. (I don’t hate anybody!) This means we had to devise ways to change the asymmetrical love-hate relationship.
- Improve Relations
To improve relations, you send a diplomat to their capital, and he will slowly increase their opinion of your country. There is a cap though, currently at +200 approval, on how much a diplomat can affect what a country think of you, so you may need to address or wait out the other reasons why they dislike you as well if you want to get perfect relations.* Your diplomat stays in the foreign capital until he is recalled, so this does limit your diplomatic freedom a little. If you recall your diplomat, the 'improved relations' opinion will slowly decay by about 3 points each year.
- Insults
If you want to make some not like you, and maybe poke them into a war, say something mean. Insulting someone, reduces their opinion of you by -25 for ten years, and will also give them a casus belli on you for a year.
Overextension
In dev diary #13, we talked about how overextension worked.*This has now changed after lots of testing and tweaking, as the original design punished early expansion, while ignoring the problem of mid and late-game landgrabs.
Now, your overextension is now a value directly related to the amount of basetax you earning from non-core provinces. So a basetax 6 province gives you 6% overextension, no matter how big you are. So, even a normal conquest in a major war, say taking 2 or 3 rich provinces, can net you a significant overextension penalty which calls for a period of consolidation.
Coring Provinces
Since overextension changed, so has how you add provinces to your core. First of all, the price in administrative power points scales depending, again, on the basetax of the province. There are several ideas that decrease it for you, and increase it for your enemies. Secondly, coring is no longer instant. It takes 3 years, not counting any modifiers, to core it. All the while you still have the overextension penalties to cost of stability and to your revolt risk. Larger countries core province much more slowly, as each non-overseas province you own will increase coring times by 5%.
An overseas province of your own culture (such as a colony) is still instant to core, and costs 10% of the normal cost to core. We don’t want to discourage you from settling the New World because of delays in adding them to your core list.
For those of you who can read our script files, this what you pay for being overextended, with each factor mulitplied with the overextension percentage.
Hope you'll enjoy a quick World Conquest now that you know how easy it will be.. And here is a completely unrelated screenshot.. just cause you know..

Code:
over_extension = {
foreign_merchant_compete_chance = -4.0
stability_cost_modifier = 2.0
papal_influence = -10
mercenary_cost = 2.0
diplomatic_reputation = -10
global_revolt_risk = 20

I assume better-sized island nations, like GB and Japan, will be favorites of would-be world conquerors.
