Welcome to this week's Dev Diary! Today I'm back to talk about some of the changes we've made to the AI for 1.34.

National Ambitions

For a long time, there has been code and script for the AI to be aware of the conditions of its missions and decisions and try to achieve some of them. But because of various issues this has not had a significant impact.

For 1.34, we’ve made sure the AI takes many of these conditions into account, especially those related to conquests. We also made the AI pursue cultural unification, depending on government rank. These changes will work together with the AI’s more organic desires to shape its ambition and strategy. The result is an effect which is just noticeable in terms of AI behavior, but compounds over time to create AI empires - sometimes historically reminiscent - that provide a real challenge to players who continue into the late game.

We were a little worried that this might cause games to all look the sa... Read more

Hyvää päivää! Welcome to this week’s developer diary where I will be revealing two new mission trees: Finland and Lübeck! As a note ahead of time, the new Finland mission tree will be part of the upcoming DLC, while we decided to grant Emperor’s Lübeck tree to Hamburg and Bremen (with the appropriate tweaks, available for Emperor owners) and give Lübeck a brand new, expansive set of missions for the base game. However, more on that further down!

Please keep in mind that the numbers showcased here are NOT FINAL and are very much subject to change based on your feedback!

During the timeline of the game, Finland rested under the crown of Sweden and had some regional development in terms of its farming population. The Finnish cavalry known as the Hakkapeliita[en.wikipedia.org] were famed for their ability t... Read more

Welcome to our next Development Diary for Europa Universalis IV! The majority of the new content for the upcoming DLC has been revealed so far and all that is missing are two nations - one of them is an island nation which almost never sees the light of day.



Prior to 1.34 Gotland was a province occupied by a rebel stack led by the Danish ex-king Eric of Pomerania. This has changed now and Gotland is selectable at the start of the game with Eric as its ruler.

Originally a commercial center situated in the crossroads between the merchants of Russia and Germany, Visby has quite an interesting history during the century prior to the beginning of the game. Home to privateers such as the Victual Brothers and the bastion of a former Danish King, Gotland ended up being the guarantee of peace between the Teutonic Knights and the monar... Read more

Dzień dobry! Welcome to today’s developer diary! We will be taking a first look at the new Polish, Lithuanian and Commonwealth trees!

But first, allow me to introduce myself. I am Big Boss, the newest addition to the Content Design team. I started playing Europa Universalis during 2011 and have loved spending time looking at and painting maps since then. More recently, I have been working on several mods, so some of you may know me from my work there. I am genuinely very excited to share with you all the hard work the team has been putting into this update and praise the immense amounts of support I have received from my new colleagues and mentors! As we delve into this developer diary, please keep in mind that the icons and event images as well as numbers displayed are by no means final!

The beginning of the game finds Poland rudderless, with her King, who maintained a union over Lithuania, Hungary and Croatia, having died a mere day earlier, after risking his fate a... Read more

Welcome to our next Development Diary for Europa Universalis IV! For today we take a look at a fan favorite™ of the Scandinavian region: Scandinavia itself.

Unlike our other Scandinavian kingdoms, the unified country of Scandinavia was never a real country. Yet it is undeniable that Denmark and Sweden tried to unite Scandinavia under their own banner during the history of this region. The Kalmar Union was the closest to a unification of these countries.

As Scandinavia is a formable with little historical ties we decided to make its mission tree into an extension of pre-existing mission trees of Sweden, Denmark and Norway. The newly gained missions are either an expansion on the current playstyle, or are mirroring key missions from the other Scandinavian Kingdoms. So let us go through the different tags and how forming Scandinavia impacts them.

As Sweden already has a very extensive mission tree the formation of Scandinavia expands the mission tree by 13 new m... Read more

Welcome to our next Development Diary for Europa Universalis IV! Today we dive into the last starting Kingdom in Scandinavia, which has not been covered yet: Norway.

As for Denmark and Sweden, the History of Norway in the Modern Age directly depended on the fate of the Kalmar Union. After the accession of the House of Oldenburg to the Danish throne in 1448, the Danish kings increasingly centralized government, even if a Norwegian Council of State formally governed the country. In fact, Norwegian landed nobles and merchants prospered under this system, as they were effectively the middlemen between the Crown and the commoners. Although some rebellions arose, such as that of Knut Alvsson, the conflicts with the Danish crown were of much less intensity compared to Sweden. This changed with the Reformation, as Frederick I and Christian III's adherence to Protestantism sparked a revolt led by the Norwegian Church. However, it was defeated in the decade of the 1530s, so Denmark and ... Read more

Hallå allihopa! Welcome to our next Development Diary for Europa Universalis IV! Today is the day where we finally get to cover the content for Sweden, so let’s get started!

Yesterday, June 6th, it was celebrated the National Day of Sweden, as the remembrance of Gustav Vasa being elected king in 1523. This was a pivotal moment in Swedish history, as it finished the union with the kingdoms of Denmark and Norway after more than one century of common government. It happened after some decades of a troublesome political relation between the Sweden nobility and the Danish kings that ended in the tragic Stockholm Bloodbath, and the already mentioned coronation of King Gustav, starting the famous and powerful Vasa dynasty, which would rule until mid 17th century.

The mission tree for Sweden recaptures the rise of Sweden to the dominant power of the Baltics prior to the Great Northern War. But it also covers other ambitions and developments of Sweden.

Hej allesamen! Welcome to our next Development Diary for Europa Universalis IV! After covering the Baltics it is finally time to switch our focus to Scandinavia, so let’s get started!

As the 13th century drew to a close, powerful social mechanisms such as feudalism and manorialism had formed deep roots in the Danish Court. At the same time, the Christian church had, at that point, come to dominate religious matters all across the Scandinavian region. At home, the royal family, spearheaded by Margaret I, would finally place a singular dynastic head on each of the three lions’ thrones, during the last years of the 14th century.

As of the treaty of Kalmar in 1397 the Nordic Crowns of Norway, Sweden and Denmark are intended to be borne by one monarch. Since its inception this Kalmar Union has been led by the Danes, the strongest and richest of the Nordic powers, close to the continent with an ambition to control and dominate the Baltic Sea area.

Eventually howeve... Read more

Hello everyone, Gnivom here today.

I may return for a future dev diary on the many AI improvements we’re making for 1.34, but today’s topic is Land Combat.

First a recap:

For 1.33, we decided to change some things with combat; first mentioned in this January DD[forum.paradoxplaza.com] and soon amended by making backrow regiments take 60% less morale damage. The core idea was to remove some weird traps that uninitiated players (I would guess a majority) and the AI (without major modifications) would easily fall for. In particular, having a large army without a full back row of artillery could be disastrous.

However, those changes also caused some unintended balance effects:

• Battles ...
