Europa Universalis IV - Development Diary 26th of July 2022

Hello everyone! Today I’ll introduce you to the new monuments we’ve designed for the next update. As before, this content will be free for all Leviathan DLC owners. Along with that, I’ll also comment on some game balance changes we’ve implemented for free in the 1.34 update.

New Monuments

As already mentioned in some of the previous DDs, we decided to introduce a few more monuments. Overall, we’re happy with the monument density we got after the 1.32 update, so we just wanted to address one specific region that was lacking in love (Scandinavia, which fits in pretty well with the upcoming DLC), and a few gaps we wanted to cover here and there. Since we had few monuments to cover this time, we also tried to get creative with the attached modifiers (you may notice some new modifiers on them, also). Let’s see:

The Falun Copper Mine was already present in the game, as a local modifier to the province of Dalaskogen. As it was the main copper production site for Europe in the Modern Age, we decided to turn it into a monument (and for those not owning Leviathan, the local province modifier will stay as it is).

Idea groups & Policies rebalance

We already talked in previous DDs about the new national ideas that we developed for some countries. Along with that, we decided to rebalance some of the existing idea groups. The general design behind this rebalance was to give again a bit of extra diversity to the different groups available, so choosing different possibilities between them might be more viable from this update. Getting into more detail, here are some of the reasoning behind specific changes:
  • Ideas giving National Manpower and Land Force limit are nerfed, to combine them with the new changes in the combat system. We felt that there were already many different sources of Manpower and Land Force available to the player and that also some ideas (e.g. Quantity) were heavily favored over others.
  • We’re also nerfing both the Economic Ideas and the Economic-Quality Policy Development Cost reduction, as we felt that we already introduced a fair amount of Development Cost elsewhere, so we saw it right to reduce it considerably here, effectively rebalancing the total amount you get from these sources.
  • We wanted to buff some of the underdogs in the Idea Groups, such as Espionage, Trade and Naval, to make them more viable compared to others in their groups.
Here you’ve got a detailed account of the changes implemented:
  • Innovative Ideas:
    • ‘Optimism’ gives now also gives +1 Leaders without Upkeep.
    • 'Formalized Officer Corps' replaced by ‘Expanded Policies’, now granting +1 Free Policies.
  • Economic Ideas:
    • Bonus now gives -10% Development Cost instead of -20%.
  • Espionage Ideas:
    • ‘State Propaganda’ now also reduces Covert Action Relation Impact by -50%.
    • ‘Vetting’ now also grants -0.1 Yearly Corruption.
    • ‘Audit Checks’ replaced by ‘Blackmailing’, now granting:
      • Reasons to Accept Vassalization +15.
      • Monthly Favors Modifier +33%.
    • Bonus gives now Rebel Support Efficiency of 100% instead of just 50%, and reduces Covert Action Relation Impact by -50%.
  • Trade Ideas
    • ‘Shrewd Commerce Practice’ now also decreases Promote Mercantilism Cost by 25%.
    • ‘Free Trade’ now also gives +2 Merchant Trade Power.
    • ‘Overseas Merchants’ now also decreases Trade Company Investment Cost by 25%.
    • Bonus now also gives +10% Loyalty of the Burghers/Vaisyas
  • Exploration Ideas:
    • ‘Free Colonies’ now gives +10% Settler Chance.
    • ‘Global Empire’ now also gives +25% Treasure Fleet Income.
  • Aristocratic Ideas:
    • ‘Noble Knights’ gives now -20% Cavalry Cost instead of 10% and +15% Cavalry Combat Ability instead of 10%.
    • ‘Serfdom’ now gives +20% National Manpower Modifier instead of +33%.
    • ‘Noble Connections’ now increases mercenary manpower by 25% instead of 20%.
  • Divine Ideas:
    • ‘Martyrs’ gives now +25% Manpower in True Faith provinces instead of +15% Global Manpower modifier.
  • Horde Ideas:
    • Bonus now also gives +10% Tribes Loyalty Equilibrium.
  • Indigenous Ideas:
    • ‘Controlled Burns’ from Indigenous Ideas gives now +15% National Manpower Modifier instead of +20%
  • Offensive Ideas:
    • ‘Grand Army’ now gives +10% Special Unit Force Limit and +15% Land Force Limit Modifier instead of 20% Land Force Limit Modifier.
  • Quality Ideas:
    • ‘Quality Education’ now also gives +0.5 Navy Tradition.
  • Quantity Ideas:
    • ‘Levée en Masse’ now gives +33% National Manpower Modifier instead of 50%.
    • Bonus now gives +33% Land Force Limit Modifier instead of +50%.
  • Naval Ideas:
    • ‘Naval Glory’ now also gives +1 Impact on Siege.
    • ‘Oak Forests for Ships’ now also gives +10% Ship Durability.
    • Bonus now gives -100% Naval Barrage Cost instead of +10% Ship Durability.
Policies:
  • Economic - Quantity:
    • No longer gives -10% Development Cost, instead it gives -5% Land Maintenance Modifier.
  • Innovative - Quality:
    • Now gives Infantry Combat Ability +15% instead of +10%.
  • Aristocratic - Espionage:
    • Now gives Cavalry Combat Ability +15% instead of +10%, and +10% Noble Estate Loyalty Equilibrium.


Crownland & Government Reform Progress

You may know that it was commented by my colleagues @PDX Big Boss and @Ogele that we replaced the tax modifier from high crownland with Reform progress growth, but for those who don’t follow as much in detail the DDs, here is a kind reminder of it:

1657651615437.png

We made an additional change to this: now each Crownland Level above 50% Crownland increases Reform Progress Growth (the modifier, not the flat value) by 20%, up from the current 10%, so the final amount of RPG you can get at 100% Crownlands is 100%. And we’ve also lowered the subsequent reform growth cost from 50 to 40. This makes for more consistent growth of RP, making it easier to progress through the expanded tiers of Government Reforms.



Governing Capacity

Along with the above change, we also decided that we could make Reform Progress Growth even more strategic, by adding a malus to Administrative Efficiency if being over the Governing Capacity - which is something that can be countered either by the Centralize State mechanic or by getting more Gov. Cap. with buildings, monuments, reforms, etc. This will certainly curb growth speed, but we think that this also adds some more depth to the game because it presents the player with the choice of how to get extra Gov. Cap. from the different features from where it can be expanded, but also an additional “How do I spend my precious Government Reform Progress” because it can be used either on the ‘Centralize State’ mechanic or in getting more Government Reforms.

Thus, the change we implemented is adding -1% Administrative Efficiency for every 2% Governing Capacity above the cap. This way it scales logically and gives off a dynamic and natural effect on the expansion speed of the country in question.

Adm..jpg

To help adjust the Governing Capacity, we made that Courthouses and Town Halls no longer require an open building slot to be constructed, similar to how Universities work, making them a more interesting type of building. Additionally, the State House building now no longer requires an open building slot, and now decreases local governing cost by a percentage of 25% and a flat -25. These governing modifiers are doubled when constructed on a Paper, Gems or Glass province.



Other Miscellaneous Changes

Aside from that, we've implemented a few more changes here and there, which we're covering in this miscellaneous section, as we think they might be of interest:

  • Slackening for Manpower now only gives 1 year worth of manpower instead of 2 years.
  • Expanding the Infrastructure of a province now increases local development cost by -25% instead of -5%. We decided against using Development Efficiency because it could end up at 0 Dev Cost for a province
  • Ramparts give 1 Combat Roll Bonus for the defender.
  • Pagan religious rebels can now force you to convert to their religion if the majority of your country has this religion. Nahuatl, Mayan and Ican are excluded from it due to their "primitive" status in the game.
  • If you have Mare Nostrum then the Spy Network in a foreign country will decrease AE Impact in that nation by -30% instead of -10%
  • Support Rebels now costs 30% Spy Network instead of 60%
  • Scorched Earth now causes +0.25 Local Monthly Devastation alongside the -50% Hostile Movement Speed for 5 years
  • Devotion now gives +25% Church Power, 25% Harmonization Speed, 0.001 Monthly Piety Accelerator, 0.5 Yearly Authority, 0.1% Yearly Patriarchal Authority, 0.5 Yearly Doom Reduction, 0.05 Yearly Karma Decay and 0.05% Clergy/Brahmins Loyalty Equilibrium additionally to the Papal Influence, Prestige and Global Tax modifiers
    Note: this change has been added to make Theocracies more fitting for other religions too.
  • Crimea now becomes a Tributary State of the Ottomans instead of a March when they seek Ottoman protection during the "Fate of the Crimean Khanate" event.

There were a lot of things to cover today! Please let us know of any feedback you have regarding these changes, as we feel today's DD is more about engaging with the community on balance changes than any other. Also, keep in mind that the numbers presented still have room for improvement, so please stay civil in discussing them. Next week the DD will be all about the great art our team has been working on for the upcoming DLC, brought to you by @SaintDaveUK . See you!

A very nice dev diary.
However, I really question the reasoning for not having courthouses, town halls and state houses not require a building slot. Why, when you want to make governing capacity more important and "strategic", take away the opportunity cost for building gc buildings? Now, as soon as you have enough money, spamming these everywhere will be a no-brainer. How does this improve the game or make these buildings more "interesting"? Mindless clicking instead of actual strategic choice is not interesting.
This decision should be reconsidered, in my opinion.
It was an interesting idea when Emperor came out, but the reality was it resulted in a lot of tedious micro for post-conquest management.

I thought somewhere in the Manchu region was a better candidate considering the culture. But this is also nice. Especially the governing cost part is interesting.

  • Innovative Ideas:
    • ‘Expanded Policies’ gives now +1 Free Policies.

  • Naval Ideas:

    • Bonus now gives -100% Naval Barrage Cost instead of +10% Ship Durability.

Fantastic changes, even a conservative guy like me can't wait to try these new effects.

I don't know how this plays out, but considering its precedent 'corruption', it will be a controversial one for sure. Especially for players who go WCing or who haven't achieved the achievement yet.

Cool, a single slot automatically reserved for every province was kinda limiting player choices IMO.

I quite like most of these changes, but i do feel that Norway was kinda left out of your "love" for this pack, because Norway do have some monuments that should be worth putting in the game, most spesifically Bryggen from Bergen that was one the most important harbours in medieval Euorpe and was still an important harbour in the 15th century as well. Why was it not decided to put in any new monuments in Norway who was alrealy quite lacking on that front anyway?

Were you able to fix the bug that makes you lose all the expanded infrastructure upon forming a new tag?
You also lose all the extra manufactories.

Oh the Quantity-Economic changes are long overdue and this will definitely shake up things MP wise. Overall some more interesting changes with other mechanics.

Support Rebels being 30% is certainly going to make things a bit more interesting with Espionage, any possibility of a Support Rebel cost modifier when it comes to Ducats cost when supporting Rebels?

As for the Admin efficiency on over governing capacity, its going to have interesting ramifications. Any chance the Advisor cost being lowered with the addition of the negative admin efficiency?
All it's gonna do is make quality eco quantity the meta instead of quantity eco quality. Really spicy changes.

Great to see new monuments, although I expected a bit more.

But yeah, wide players are favoured again over tall players with Economic being nerfed... Now that AI is even more expansionist too, there's no room for tall play, it's just map painting now.

It was repeatedly asked for as a QOL change by players since they don’t want to go through every individual province deleting AI buildings

I am a little bit concerned about the changes to development costs in the idea groups, in that they might be balanced around mechanics only available through DLC. If the thought is that there is more development growth through consolidating or landmarks, people who don't have the DLC are kind of pushed away from tall play.

@Pavía If we’re only getting a potential -10% dev cost from picking eco instead of the potential -30% that we have now, I feel like it should be something different so that it is actually impactful. A fun idea I had as finisher could be to give 5% dev efficiency and reduce the requirements for expand infrastructure so that you can do it more often ex. (every 10 dev instead of 15) I feel like this will be much more impactful for tall nations while severely limiting its impact for wide nations as they really cannot expand infrastructure now that they will lose a ton of admin efficiency which would not be worth it for them in that play style. On this note, more of a flat gov cost hit may be in order if these buffs were to get implemented.

Also, maybe 2.5% or even 1% dev efficiency on expand infrastructure in addition to what we have now would be a good bonus. Once you get above 40 dev, even all the dev cost reduction modifiers remaining and to be implemented in the game don’t have too much of an impact.

Edit: Also, now that gov capacity has the admin efficiency debuff so large nations realistically cannot use it much, maybe the other modifiers for expand infrastructure could be buffed as well ex. more local trade efficiency/defensiveness/tax/manpower/etc. Make expand infrastructure the tall mechanic it was meant to be and now can be!

Edit2: I would love to know why some people are so vehemently opposed to buffing playing tall to make it more competitive (e.g. staying small being a somewhat winning strategy to a point) - if you play wide none of this will impact you and it makes the game and the tall play style more fun for the fairly large amount of people who do it. If there is some way you will think this will make the game worse please bring it up for discussion!

Has anything been done about that stab hit event "spread of humanist ideas" in Innovative Ideas? It does nothing but make an under-picked idea group even worse, and it makes much more sense to move the event to Humanist.

Now that you've changed courthouses to have +1 building slots, nerfed eco and nerfed quant (which most mp rebalance mods do), are you going to revert the cannon backline change, like most mp rebalance mods do? They do it for a very good reason; the change makes combat worse.
Also, +1 rolls from ramparts is a terrible idea.

If you are touching idea groups, maybe take a look at "Factories". It's fort bonus doesn't make a lot sense for someone expanding with colonies, since your rivals are unlikely to be anywhere close. Perhaps a fort maintenance reduction would be better for a large sprawling country?
