EU4 - Development Diary - 23rd of October 2018

Hello! We’ll finally reveal some features of the upcoming Immersion Pack coming with the 1.28 patch. However I need to warn you: HEAVY USAGE OF CODER ART INCOMING!

Our artists nor me have had time to get our hands on the new features yet to make sure the interface is up to par for user usage. So everything is just how the programmer left it. Terrifying thought.

We’ll start with a feature only available to the Catholic Iberians. Establishing Holy Orders. Keep in mind numbers are as usual up for tweakage!


These are inspired by Jesuit Reductions in the new world but an Iberian nation can put them anywhere as long as the nation own the entire state and that it is fully cored and stated. The available orders are: The Society of Jesus, The Order of Preachers and The Order of Saint Francis.

When an order is selected for a state these following effects are applied to all provinces in that state.
  • Jesuit Order
    • +1 Tax Development
    • 1.5% Local missionary strength
    • -10% Local Build Cost
  • Dominican Order
    • +1 Production Development
    • Removes slaves if trade goods and replace it with something else
    • -30% Culture Conversion Cost
  • Franciscan Order
    • +1 Manpower Development
    • -3 Local Unrest
    • -0.05 Local Monthly Devastation
Each of these costs 50 monarch power to put in place, 50 of the type that order represents. Administrative for Jesuits, Diplomatic for Dominican and Military for Franciscan. As an overlord of a colonial nation you can still place these in their land. The AI will know if a player is involved and restrain itself from placing these orders themselves letting the player optimize their usage.

For the few that manages to recreate the Cremé Pheonix, an Andalusian Muslim, we'll see what we can do for you ;)

Next Feature is one for every colonizer which we have done together with trying to improve the Colonial Diversity, to try and prevent the Colonial AI to spend so much dip points on purging away cultures. Instead allowing the Americas to become the melting pot of cultures it was. Also yet again I warn you that everything you see is in a state of work in progress.


With Expulsion of Minorities feature you can now tell those damned Puritans in East Anglia to head off to Plymouth Harbor and get on the Mayflower.

Using this costs you diplomatic points akin to how much it would take to culture convert in that province, but upon colony completion it both converts the religion and culture of the province while making the colony have the old religion and culture of home. Also upon completion you get some extra development in the finished colony based on how big the home province were for the minority you sent to live in the colony.

Besides the Culture conversion cost modifier reducing the cost to do this action, in Exploration ideas there is now an idea that will also reduce this cost if you own the Immersion Pack.

Now I’m going to hand it over to our beta who have helped us out with the map in this iteration and helped us overhaul the Spanish Main.

Hello, I’m Evie. You may remember me (as GuillaumeHJ) from old Dev Diary classics like “How to add provinces to Western Africa without getting bored” and “There’s no such thing as too many provinces in North America”. For those of you who joined us since Art of War: nice to meet you.

As you can probably gather, I’m here to talk to you about more map changes. After all, it’s one thing to add provinces to Spain, but much of Spanish history in the Europa Universalis timeline happened outside Spain, in the part of the world that would receive the apt name of “Spanish Main.”

Stretching from the coast of Texas all the way to the mouth of the Orinoco, across the Caribbeans, and back into Florida, the Spanish Main was the heart of the Spanish colonial empire, where the great Treasure Fleets sailed to gather the wealth of the New World. As a result, the “Spain” update also includes extensive additions to the region.


Map-wise, the changes are extensive – upwards of eighty new provinces and twenty new tags in Mesoamerica, Central America, the Southwestern United States, the Caribbeans, Florida, Colombia and Venezuela. But Cuba and Hispaniola are now up to nine provinces. Colombia and Venezuela get a plethora of new provinces as well along the coast, bringing them much closer to the density found in Central America. The lion’s share, of course, goes to Mexico, especially the heart of Mesoamerica.


The most important (and by far the most requested) of those provinces are, without a shadow of a doubt, the two we split off from the original Mexico province, representing Texcoco and Tlacopan, the two cities that (along with Mexico-Tenochtitlan) formed the Aztec Triple Alliance. Reducing the Valley of Mexico and the Aztec power base to a single province always felt wrong, so when the opportunity came to update the region’s map with smaller provinces, adding these two was the very first item on the list of changes that needed to happen.

More than new provinces, though, the heart of the update is the new tags. Nine in Mesoamerica proper, six in the Mayan regions, six in the deserts around the US/Mexico border, and one each in Central America and Colombia bring a great deal of depth to the region. Who are they? Read on to find out.



Northwestern Mesoamerica, beyond Colima and the Tarascans, is often thought of as a void, but actually it was a Greece-like patchwork of cities. Representing them all is beyond the scope of this patch, but we’ve added two of the more significant local powers, Tonala and Xalisco, to bring relief to the area.

At the northern edge of Mesoamerica lived a plethora of people that the Aztecs collectively called the Chichimeca (roughly compared with the Greek “Barbarian”). Though they didn’t have the great cities of Mesoamerica proper, they played a fundamental part in regional history, and provided formidable resistance to Spanish expansion for half a century. For them, we’ve added three tags: Otomi and Guarames are two of the more significant people, while Chichimeca covers a variety of smaller groups.

Near the Chichimecan, we find a historical oddity: a Mayan group that wandered far from Yucatan and Central America, to the opposite end of Mesoamerica, the Huastec people.

Closer to the Aztecs, a number of additional states represent various regional powers of some note. To the south, Coixtlahuaca, a mixtec kingdom, fell early when their king defied the Aztecs. To the south-east, Teotitlan became a loyal ally of the empire. To the west, meanwhile, Matlatzinca served as a buffer between Aztecs and Tarascans - until the Aztec invaded it, precipitating war with their powerful rivals.

The South: Mayans, Central America and Colombia.

Further south, the Yucatan peninsula was home to about sixteen Mayan polities in this timeline. Having them all would, again, be impossible, but instead of just having the two rival dynasties of Cocomes and Xiu (whose rivalry dominated Mayan politics in the era), we’ve added two of the better known late post-classic city-states, in the form of Can Pech (Campeche) and Chactemal (Chetumal).

In south-eastern Mexico, a pair of additional Mayan tags add depths to the Tabasco and Chiapas regions. In the former, they’re the Yokotan (or Chontales), who claim descent from the ancient Olmec civilization. In the later, the Tzotzil, one of the more significant local group, serve a similar role.

In Honduras and Guatemala, the Kiche kingdom no longer can afford to get complacent – their perennial rivals (and erstwhile vassals), the Kaqchikel, are now in the game plotting to gain the upper hand, while further east, the Chorti people could also turn into quite the threat.

In Colombia, the Tairona, sister people to the Muisca (who are already in) form a new addition at the northern edge of the country, where the last of the Andes come to die in the Atlantic.

Last, but not least, we have our first non-Mayan Central America tag, based in the coastal jungles of Nicaragua: the Miskito people, who remained independent of Spain long enough to become a British protectorate instead.

The North: Pueblos and Natives.


To the north, we find ourselves drawn to the upper end of the Rio Grande valley. There, the old Pueblo tag has been split in three to represent the various groups that together formed the Puebloan people. In addition to the old Pueblo tag (now limited to the Rio Grande valley itself), we now have the Keres tag (covering famous pueblos like Acoma and Zia, to the west of the Rio Grande), and the Zuni one, near the New Mexico/Arizona border.

Beyond the Rio Grande valley, our additions take the form of Native American tags. Adding depths to the Apachean people on top of the already-present Navajo and Apache tags, we find the Lipan and Mescalero ready to make trouble for colonizers in New Mexico and Texas, where they were a formidable obstacle to the Spanish historically. Further west, in the foothills of the Sierra Nevada, California finally get representation of its native people in the form of the Yokuts. Finally, in the deserts of north-western Mexico, the Yaqui people, who resisted Spanish then Mexican dominion into the twentieth century, join the fray.

Together, all these additions bring a lot more depth to the areas of the map that ended up being conquered by Spain.

Thanks Evie! Next week I'll be back to talk about more features, one of which that Sweden had quite an excellence of building ....

We’ve also made some changes to the colonial regions of the west coast:


In addition, there are 2 new colonial formable nations in the Americas: California and Texas.
Each of these costs 50 monarch power to put in place, 50 of the type that order represents. Administrative for Jesuits, Diplomatic for Dominican and Military for Franciscan.

You have the Jesuites (sometimes refered to as Gods Soldiers from their founders soldier career and their fighting spirit) and the Dominicans (also sometimes refered to as Domini Canes for there role in the inquisition) and you have the Franciscans represent the military faction? Realy? :D
Nice new Features, but what we rly need is stuff like delete fort in colonial nations so they don't go bankrupt over and over. Also a way that they don't get WE if your permanently at war, just on other continents

Is it the Vasa???
Interesting, maybe that will finally get me to play in the Americas.

Are there further plans regarding colonial nations like giving every historical CN unique NIs or changing the way their liberty desires play out?
Will these additions prevent all the colonizable lands from being well... colonized in 1821? As of currently, if at least 3 of the major colonizer don't die early, they just colonizable EVERY SINGLE PROVINCE without exception, while I can see it happening in some games it shouldn't have to happend every time the starts aligne and Castille-Portugal-England all dies a painfull and early death

Holy Orders are very underwhelming imho.. Just another button that cost X and gain X permament bonus in region.. No real gameplay in it, there is no thinking about investment, if you have the spare points you will click it (since it's cheaper then normal development) else probably not. There should be missions for the orders, with the orders spreading the faith/culture and colonizing the new world, making the local population join your cause.. It was normal for Jesuits for example to go to uncolonized areas and establish jesuit outposts there and work on converting/settling the region.. Right now you just have to control a state, press button, get bonus. The name is the only flavor (and possible some 2-3 events?).

Again, this is just my opinion, anyone is free to disagree with me.
You have the Jesuites (sometimes refered to as Gods Soldiers from their founders soldier career and their fighting spirit) and the Dominicans (also sometimes refered to as Domini Canes for there role in the inquisition) and you have the Franciscans represent the military faction? Realy? :D

What MP is used is dependent on what they do in those colonies, not on orders themselves. Jesuits were focused on reading heathen texts and making conversion procedures, so the state helps them with Administrative Powers.
Dominicans spend time on the field with the people, so the state helps them with diplomats.
In the same vain, Franciscans are helped by the country's military resources.
sorry but im confused. When and why would one use the Expulsion of Minorities feature?

Good job on the map changes (though I thought you guys were putting the Europa back in Europa universalis and most map changes are now in the new world)
Ok the expel minorities thing is cool, any chance we can colonize with our minorities even without expelling them? In fact we should probably only be able to colonize with cultures that have coastal provinces, it always feels odd when you colonize as Timurids that the islands of the indian ocean become uzbek.

Secondly I like the mass of new provinces but they won't be a buff to spain if spain doesn't get a more consistent way of conquering them, today it barely ever does.
Oh and the carribean should either be made into a trade company region or broken up into smaller colonial regions.

And thirdly I am a bit sad to see the state screen used up for buttons like this, I was hoping that some buildings would get moved there, in particular universities.
