Europa Universalis IV - Development Diary 28th of June 2022

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 against the Ottomans at the battlefield of Varna. Thus, Poland starts at a quite precarious state: a vacant throne, the Nobility’s Golden Liberty in full effect, and surrounded by powerful neighbors. At the same time, the Ottomans in the South and the Muscovites in the East are taking great steps to consolidate and expand their domain.

So what’s new for Poland? For starters, they have access to two new T1 Government reforms. The first one is the Great Sejm reform, granted to them at game start:

2.png

Bear in mind that any and all numbers you see in this Developer Diary are strictly work-in-progress and are subject to change, especially in response to valuable feedback from the community!

The second T1 reform is a special reform for Poland upon accepting the Union with Lithuania:

Unlike the Great Sejm reform, the Polish Elective Monarchy grants the ability to elect various princes to the throne, a steeper absolutism malus and, similarly to the Great Sejm, it enables the Parliament and grants a reduced Unrest bonus.

Speaking of the union with Lithuania, it should be noted that some changes were made to that event. Now, it will fire even if Lithuania is a player. A Player Lithuania will be able to decline, but AI Lithuania will always accept. This was done in order to further facilitate the idea that Poland and Lithuania make a great co-op campaign, which is also complimented by both mission trees granting bonuses that follow the spirit of cooperation between the two nations. Here’s how the new event plays out:

3.png

4.png
To further immerse the players into the gravity of their choices, I went ahead and added a few dynamic missions for Poland, based on your choice between the local noble or the Lithuanian PU. Accepting the Lithuanian union will lead you towards developing the Lithuanian core as well as elevating their nation financially and (later on) artistically as you prepare them for the eventual integration:

5.png

6.png
This branch ends with you declaring the Imperial Commonwealth, which grants a powerful temporary bonus:

7.png

On the other side, declining the PU with Lithuania will grant you the path that leads you towards the West via entering the Empire, leading it and passing reforms.

8.png

Note: You will still receive claims on Lithuania and be able to form the Commonwealth!
The first mission’s reward is an event for the current Emperor to admit you in the Empire:
31.png
This path will also contain new and innovative rewards such as the new modifier ‘Reasons to Elect’:

The final mission for the Imperial path of the West will imbue Poland with a sizeable bonus to their Imperial Authority Gain as well as extra Diplomatic skills for her ruler.

Main Body of the Polish Tree​

Addressing the aftermath of the Varna crusade will have a profound impact on the rest of the missions further below. Opting to pursue friendship with Hungary and/or Bohemia will lead both parties to a shared sphere of prosperity, historical friendship and powerful bonuses to last as long as the alliance is maintained. However, should you choose to rival and become antagonistic towards them, the reward will switch to a PU CB / Permanent Claims based on the country’s union eligibility. To be clear; you can pursue friendship with one of them and antagonize the other, the choice rests entirely with you!

2Yf_ckUJUFNu5aCHKpYrLOTQczg4pZzdcIS-4tR7vAYoe3dei43MniG3iVD83F9PKO6G-QlzgVIP9iFqq46ahbZJzb8vDx39qBWs4NN1bTJxoQRVQEhoEIHAL477R9zEdo6Qm7VEpX1GFcYvJGQ

Internally, Poland needs to address the growing influence of the nobility. Regarding that, in the mission ‘Leverage the Magnates’, you are granted the opportunity to cooperate with them and win their favor via great concessions or directly oppose them. Keep in mind that due to their tremendous influence, opposing them is quite difficult. Working alongside them will reduce the cost of Parliamentary Bribes (which will be increased by default for 1.34) and grants a small Loyalty bonus until you pass further legislation as the Commonwealth to reduce their authority. Alternatively, if you dare to oppose their authority, you will gain an event to face a major uprising of Magnates that will also reward you with a unique new modifier:

image (42).png
The missions directly below it follow the turbulent history of Poland and will have you attempt to pass legislation and reform the government by undoing nobility influence. Choosing to oppose the nobles in the mission shown above will also impact the following few missions!

The mission ‘Great Sejm’ will unlock a new personality type ‘Reformist’ which grants more reform progress growth as well as new unique Parliamentary Issues for Poland! The new personality can be assigned to all rulers with at least 4 Administrative Skill.

Resolving the matter of Hungary and Bohemia will yield dynamic rewards based on whether you completed them via conquest or diplomacy. This also impacts the reward for ‘Balance the Princely Lands’:

14.png

Moving on, you will also be tasked with harnessing the Polish Renaissance, dealing with the Piasts of Mazovia and developing Krakow:

image (31).png

image (32).png

On the Conquest front, you will be led towards quelling Roman’s Rebellion in the South and seizing control of Wallachia, raising troops from nobility strongholds and assisting the Prussian Confederation:

15.png

17.png

18.png

Note: Assisting the Danzig merchants may lead to the formation of Royal Prussia as a subject under the Polish crown which will have its own few missions to break free from your hold!

Of course, the Polish tree holds many many more cool new additions, events and rewards and they are up to you to discover!

Finally, Poland (and the Commonwealth in general) will have access to a new special unit, the Winged Hussars! I am very excited to finally talk about this new unit.
  • They will be available for Poland and PLC via a national idea
  • In our current build you may recruit 1 Winged Hussar per 100 Development
  • They come armed with +1 Cavalry Shock and +100% Reinforcement Cost
  • They are further empowered by your choices in the mission tree!

image (33).png

The Winged Hussars have arrived!

As a side note, we currently have not chosen yet what colour the Carolean and Hussar unitbox will have. Janissaries are red, Cossacks are orange. Feel free to suggest potential colours!

The Lithuanian Mission Tree​

Alongside Poland, Lithuania will be getting her very own missions. It builds upon the old mission tree and greatly expands it, honing and improving upon the unique aspects of playing as Lithuania:

19.png

Among the highlights of the Lithuanian tree are the ability to call upon a host of Cossacks, new unique T1 Government reforms (yes, plural!) and the potential to utilize the Tribes Estate for a limited time.

21.png

22.png

23.png
Alongside these new additions, Lithuania will gain access to new events and flavor:

24.png
If you choose to remain as Lithuania for a little longer beyond Administrative Tech 10, we made sure to accommodate your stay with flavorful missions that will entice you to stick around a while in order to get all the rewards and complete the tree:

25.png

The Commonwealth​

Building upon the solid foundation that is the Polish mission tree, Commonwealth missions originally appear as part of the Polish tree, marked as “Locked Missions”. Unlike other formables, we took the creative decision to showcase the Commonwealth tree to the Polish player, before accessing it. The reason behind this is to prepare the player for whatever challenges and requirements the PLC missions will ask for and ensure the player is not caught off guard.

Thus, if you hover your mouse over the Locked Missions, you will see the requirements as well as potential rewards beforehand.

Now that’s out of the way, let’s take a look at some of the missions we have in store for the Commonwealth, starting with this one, my favorite, ‘A Lifetime of War’

10.png

26.png
Note; Since the mission only requires one of the listed requirements for it to be completed, you may see fewer choices in your version of the event, based on which way you choose to complete the mission. Shape and sharpen your army the way you want to!

Note: Please be aware that these numbers are not final!

A PLC tree would not be complete without its ‘Invest in Eastern Poland’ Mission, which requires you to have 40 provinces with a manufactory or a level 3 Center of Trade and either 40% Global Trade Goods Produced or 7 ‘Trading-in’ Bonuses. Here is the reward:

image (34).png

Following in the steps made before forming the PLC, and after completing the Great Sejm mission, you will gain access to flavor missions that will assist you in passing and repealing the Articles of Agreement (Pacta Conventa) and even rewriting them completely from scratch, with more favorable terms on the behest of the monarch, if you chose to oppose the Magnates in a previous mission:

27.png

The conclusion of the major flavor part of the tree is the mission ‘Dominate the Markets’ which grants a new mechanic we made specifically for the PLC, the ability to reset or extend a Golden Era:

image (38).png

image (35).png

External Affairs of the Commonwealth​

No major mission tree would be complete without a robust conquest path. That much is true for the PLC, which will be granted missions, a new Casus Belli and even gain Streltsy as a one-time reward from one of their missions:

image (36).png

image (37).png

29.png
Moving on, ‘Prevent the Deluge’ will task you with dealing with whoever the ruler of Scandinavia is, be it Sweden or anyone else. You may deal with them in a multitude of ways, including diplomacy or conquest. Should you choose to approach Sweden diplomatically, both nations will be positively impacted by a wave of prosperity. Sweden will gain +25% increased production for its metals and historical friendship while you will gain direct access to Scandinavian copper and iron, reducing your overall military costs:

28.png

The final conquest mission for the Commonwealth will set you up to become a supreme great power, requiring you to be a hegemon and have a tremendous amount of development under your belt:

30.png

Note: Development Efficiency’s number will be green in the final build!

The philosophy of the PLC missions is that of a tree whose content should last the average player till around the 1700s at the very least, so expect a lot of hard work and very worthwhile rewards from every single mission in this tree!

While we are on the subject of the Commonwealth, I would like to showcase some new implementations that the team worked hard for. As I mentioned above, the PLC will now enjoy a lot of new content including 2 different sets of National Ideas. One for nations whose primary culture is Lithuanian and one whose primary culture is not Lithuanian (namely Poland as an example):

Polish PLC Ideaset:

Code:
PLC_ideas = {
    start = {
        nobles_loyalty_modifier = 0.1
        num_accepted_cultures = 2
    }
 
    bonus = {
        monthly_reform_progress_modifier = 0.25
    }
 
    trigger = {
        tag = PLC
        NOT = { primary_culture = lithuanian }
    }
    free = yes
 
    plc_prosperous_folwarks = {
        global_trade_goods_size_modifier = 0.10
    }
    pol_jagiellonian_university = {
        idea_cost = -0.10
    }
    plc_the_obrona_potoczna = {
        drill_gain_modifier = 0.25
        army_tradition = 1
    }
    pol_winged_hussars = {
        cavalry_power = 0.3
        can_recruit_hussars = yes
    }
    plc_refine_our_golden_liberty = {
        monarch_admin_power = 1
    }
    pol_royal_guards = {
        infantry_power = 0.10
    }
    plc_tempered_by_neighbors = {
        discipline = 0.05
    }
}


Lithuanian PLC Ideaset:

Code:
PLC_LIT_ideas = {
    start = {
        global_manpower_modifier = 0.25
        tolerance_heretic = 3
    }
 
    bonus = {
        governing_capacity_modifier = 0.15
    }
 
    trigger = {
        tag = PLC
        primary_culture = lithuanian
    }
    free = yes
 
    warlord_dukes = {
        max_hostile_attrition = 1
    }
    plc_tempered_by_neighbors = {
        discipline = 0.05
    }
    new_magdeburg_laws = {
        development_cost = -0.1
        global_trade_goods_size_modifier = 0.05
    }
    reciprocal_guarantee_of_two_nations = {
        all_estate_loyalty_equilibrium = 0.05
        diplomatic_annexation_cost = -0.15
    }
    lithuanian_hussars = {
        cavalry_power = 0.2
        can_recruit_hussars = yes
    }
    statutes_of_lithuania = {
        global_unrest = -2
    }
    lithuanian_renaissance = {
        technology_cost = -0.05
    }
}

Special thanks to Verinity Void whose National Ideas work was partially adopted for the Polish PLC ideaset!

I am at your disposal for any questions you may have about the trees, as I’d love to read and answer your feedback, and also feel free to suggest tweaks as well. Thank you for taking the time to read my very first Developer Diary! Next week my colleague @Ogele will come back, to talk about some sea-related new content.

Hi all,

Just wanted to chip in a few of my comments. First of all, I do enjoy the fact that there will be more missions in general. I often play with Missions Expanded for that very reason, though it often makes the game too easy. Nevertheless, regarding the updates:
  • I agree with some comments regarding the elective monarchy that it could be improved. At least I can see how foreign countries use their favours to further increase the chances of their relatives. However, I do believe that elective monarchy should be only enabled in the XVI century. At that time, the last of Jagiellon was infertile and could not produce an heir. I can see how such a situation is handled similarly to Burgundian Inheritance where a ruler is pre-defined and unable to produce heirs.
  • I really look forward to how Royal and Ducal Prussia will be handled. I can imagine that Royal would be immediately integrated into Poland with Burghers' privilege granting 50% autonomy in their provinces. Again, similarly to what is done to Low Countries as one of the potential outcomes of the Burgundian Inheritance. I hope Ducal Prussia can provide enough bonuses to leave it as a subject while forming a Prussia together with Brandenburg (or on its own). The +50% to liberty desire it has towards Poland would add to the instability (I learnt it the hard way when doing Silesian 'Back to Piast'). If the formation was done with elector Brandenburg, one can see a possible Imperial Diet forcing HRE Emporer to declare war to liberate the Elector.
  • The 3rd May Constitution played a big role in PLC's history as some have already flagged. However, it was a response to the Second Partition of Poland. As such, I can see a looming disaster, where enacting the constitution is one of its possible outcomes - mainly, because if not for Partitions, who knows if there would have been a constitution? In any case, the constitution should grant neighbours a CB to dismantle Poland/PLC.
  • Many raised concerns about how overpowered Poland and PLC may become. I agree and to mitigate it I suggest revisiting how rebellions are handled. The internal instability was the main cause of PLC's fall. If the spawned rebels were draining the country's manpower, suddenly the struggle for power would become very dangerous. Imagine all your manpower lost because those very people decided to rebel against you! What better opportunity to attack a country that cannot reinforce its troops? This could actually make supporting rebels far more convenient. Add some additional negative factors depending on the type of rebels (e.g. penalty to goods produced with these are peasants). Also, what about regiments created in provinces that are rebelling for independence? We could see them becoming hostile or having lower morale and being unwilling to fight their folk. With this in mind, suddenly The Little Kings Uprising could be deadly. True, one could just hire plenty of mercenaries, but this would be very costly and reduce army professionalism, which is required to be 100% for a Lifetime of War. To that matter, even the Castillian civil war could be dangerous (Aragon, France), and it would be definitely not possible to get PU over France when playing England and having at the same time both war with France and War of the Roses. Finally, it would add some more realism by preventing fighting multiple wars at the same time, while having a multitude of rebels (as long as no forts are occupied and while the war lasts - who cares, right?)
Overall, I can see how playing Poland/PLC would not be a simple blobbing but indeed gentle manoeuvring between dealing with internal instability and trying to conquer some lands to stop perhaps Russia from forming or the Ottoman blob. I think that with plenty of rebels, it could be a very different type of gameplay.

Keep up with good stuff and all the best!

But theyre so low dev, and due to being an empire you have high gov capacity so would want to conquer, especially with your permaclaims
Muscovy is duchy at the start and can't upgrade gov until it forms Russia

russia likely getting buffs too this patch
They said there will be no changes to Russia, only Novgorod gets a new government at empire rank

Not a lot of people know, even Poles themselves, but elective monarchy in Poland existed since the death of Kazimierz the Great the last Piast king of Poland. Poles tends to think Elective Monarchy was tied to proclamation of Commonwealth, which is not true

I've noticed a trend for a lot of unique units to be a bit "generic," but have the ability to be adaptable to the player's preference/strategy. Is this just a test for this expansion or a considered design choice for the future?

I like that Poland is getting more flavor, but in the second part of the Dev diary the bonuses get utterly crazy. +1 dice roll on own territory UNTIL THE END OF THE GAME is just overkill. In general I would say that all the decisions for that event are just too big to be given for the entire game. They need to be time bound. Also, I don't want to sound as a fun killer, but having a second or extended golden era is so broken. During the golden era a country can make a qualitative jump forward as the bonuses are numerous and quite substantial and the most important is all powers cost. Having such an opportunity twice is very unbalanced. I would like also to see some logic kept even in alternate history scenarios presented in the mission trees. There is no rationality in having a mission give a permanent historical friendship modifier towards Poland to the dominant Scandinavian power. All Scandinavian powers in the Baltic, be it Danemark or Sweden, were striving for complete control of the Baltic ports so they could control the trade of nations like Poland and Russia, as those did not always have easy access to the sea and to European markets. This was always a strategic interest of any Scandinavian power and always put them in conflict with powers on the other side of the Baltic sea. Also, will there be additional changes to Russian tags in the upcoming patch? They are now looking really week in comparison to their neighbors and some balancing might be needed.

Ahem... On this occasion, I have a question... Ruthenian starting tag when?
Never, I guess. At the start of the game there was no independent state in the region. I would like to see a disaster though for Poland or some events that would trigger a separation of the Cossacks like it was historically after the Lublin Union. Something that is not shown in the current game is that the Lublin union triggered heavy unrest in the Orthodox lands as previously those lands were under Lithuanian rule and in the context of the Duchy of Lithuania, Ruthenians enjoyed pretty much equal status with Lituanians. A lot of Lituanian nobles were Orthodox Ruthenians and Ruthenian was a widely used script in administration. The right of the Orthodox church were respected. Under the Union of Lublin, those lands passed under the control of the Polish crown and Poland moved towards a forcible union of the Orthodox church on its lands with the Catholic one, creating the Uniate Church. Previous Ruthenian nobles started to adopt polish customs and converting to keep their privileges, while others fled. The lower classes and the Cossaks started to mutiny. I'd like to see that reflected and triggering a possible involvement from Russia or Muscovy and a struggle for the Zaporozhian Cossaks to balance those two powers in its favor and keep its independence and expand.

I stand corrected.
However, as I understand, it was Jogaila (Władysław II Jagiełło) who convinced the nobility to elect rulers only from his dynasty. Once that dynasty ended in the XVI century, elections, as we know them, began (until the 3rd May Constitution which aimed to introduce hereditary monarchy). Hence, I suggested introducing the election mechanics in the game a bit later to reflect that. Nevertheless, I see the point in leaving elections from the beginning - it still allows for role-playing.

Heya folks, just wanted to pop in and let you know that based on your feedback I went ahead and made some tweaks to some aspects of the PLC! So let's take a quick look:

  • Removed the Military Tactics bonus from the Modernized Fire Ranks modifier, it now grants Own Territory Dice Roll Bonus +1 only
  • Added a big malus to reform progress growth for Poland's 2 New T1 Reforms to reflect history more realistically. Similarly, undoing the Golden Liberty Privilege will grant you a new reform that will place the PLC somewhat near Russia's Tsardom power
  • Made some tweaks for PLC's idea set.
    • No more reform progress growth in the ambition, it now grants Tolerance of Heretics
    • Instead of +1 Ruler Admin Power, you now get +1 Country Admin Power, so you can still benefit from it even after having 6 ADM Rulers
    • Infantry Combat Ability buffed to 15% from 10%
  • Hussars no longer cost 100% more to reinforce. Instead, they Reinforce 50% Slower and now also have -25% Drill Decay (They still deal +1 Cavalry Shock)
  • PLC Lithuanian Ideas are now called "Lithuanian Commonwealth Ideas" and I am considering renaming the PLC into LPC if formed by Lithuania
Let me know what you think and keep that feedback coming, I may not respond to every message but rest assured that I genuinely value your feedback and read through every single message <3

Until next time!

I disagree with the removal of the tactics bonus. It would have been a far more useful military modifier than the +1 rolls on own territory, because realistically (or at least how I play the game), if you are going to war, rarely any battles happen in your own territory, except maybe in the early game, but the modifier would come later, making the bonus useless 90% of the time.

If you mean adding full name like "Polish Lithuanian commonwealth" or "Lithuanian Polish commonwealth" go for it.

On the topic of tweaks and communication, please remember we have already said "No New Tags" introduced in the game. The reason behind this is that new tags (even when not active) pose a great strain on the performance of the game. I really wanted to have the Latin Empire appear as its own tag but for now it's just Byzantium with another name (or perhaps a modifier if you are Catholic?) and *potentially* Crusader ideas (based on whether or not you will like this suggestion!)
Let me know what you think and what the best way to tackle this issue might be, from your perspective!
