EU4 - Development Diary - 20th of August 2019

Good day and welcome to another EUIV Dev Diary. This week we shall be tackling the Ecumenical matter of Catholicism in the game.

Catholicism is a bit of a funny one when it comes to religions in EUIV. When the game came out, it was one of the few religions that actually had mechanics attached to it, which helped in making it an attractive choice, both in terms of power for your nation, and flavour for your campaign. Over the many years of EUIV's updates and expansions, many religions across the world have been given their own mechanics and flavour, leaving Catholicism in the lurch. Its mechanisms have dulled in the face of those from other Christian denominations, and it is often blasted as a poor pick of religion for a budding European power, when Protestantisms and the Orthodox and Coptics are such tantalising alternatives.

In the upcoming European Expansion, we want to empower the Catholic faith, and bring a sparkle back to the appeal of remaining faithful to Rome, as well as allowing the Papal States themselves to thrive in the power and authority as being head of the faith, and really feel the impact of the faith being torn apart when reformation hits.

Firstly, as anybody knows, the root of all power is money. To this end, the upcoming expansion will be introducing the Papal Tithe. There will be a treasury in the game, not owned by any nation but belonging to the Curia itself.

As will be a common theme, numbers and UI are far from final

The Curia Treasury fattens up based on the number of Catholic nations in the world. The money is not taken from the nations, but rather is added to the Curia based on the amount of Crown Land held by the Clergy Estate in these nations. Nations who pass the Dissolution of Monasteries will stop their lands from contributing to the Tithe.

The Tithe can also be directly paid into by particularly pious nations. Nations can buy indulgence which pays directly into the Tithe, and in addition to feeling relief from avoiding purgatory, can enjoy added Papal Influence and temporary defence from Excommunication.

The Curia Treasury can of course be dipped into, and the privilege few who can do so are the lofty Curia Controllers themselves. Each Curia Controller can pass one Papal Bull in their tenure, which is an action the exclusively costs money from this Curia Treasury. Papal Bulls are unique actions that affect all of Catholicism:

  • Illius qui se pro divini: Enables Crusades after the Age limit is imposed.
  • Apostolicae Servitutis: 50% Cheaper Curia Powers (Levy Church Tax, Proclaim Holy War etc..)
  • Praeclara Carissimi: -5% Development cost
  • Immensa Aeterni Dei: -10% Embracement cost, 25% Institution Spread
    Cardinals will spread institution if the institution has been embraced in a province of another Cardinal or the capital of the Curia(Rome).
  • Libertas ecclesiae: +20% Imperial Authority Growth
    Available if Emperor & Catholic Empire. (Not White Peace)
    All Catholic Nations in HRE get +15 towards approving HRE reforms
  • Dei Gratia Rex: +0.5 Yearly Absolutism & -2 Unrest in Catholic Provinces & -25% Drill Decay
Costs for these are a base of 1,000 ducats from the Papal Treasury, and increase as Reform Desire does. If devout Catholic nations wish to maintain the ability to empower their entire faith in the face of growing Reformation Desire, then they will have to expand Catholic lands or force convert their heretical neighbours.

The Pope himself has also been empowered with the option, but not the obligation, to play as a Kingmaker within the Catholic Faith. Cardinals will still spawn within Europe, but the Pope has the choice to directly appoint cardinals to other nations out of his own pocket.

The Papal State can assign Cardinals to nations who he thinks will best serve Catholicism. The cost for doing so is relative to the target nation's development and number of existing Cardinals. The Papal State will enjoy added influence to becoming the Papal Controller themselves through this action, and the target nation will have a longstanding boost to relations towards the Pope. Of course, the Papal States can assign Cardinals directly to their own land, but this action will come with a boost to their corruption. To make the traditionally invisible Cardinal mechanic somewhat more omnipresent, Cardinals are now visible on the (placeholder?) religious mapmode.

Finally the Pope can himself add directly to the Tithe with his own treasury. This may be of use for a particularly expansionist Pope who dismays other Christians by declaring themselves Kingdom of God. This Decision will no longer disable Curia mechanics.

Italy and Catholicism remain focus points for the upcoming Update and Expansion, and we're not done talking about them. When the situation in Europe gets a bit spicy thanks to theses being nailed onto doors, there may be more popping up, but for now that's [REDACTED]

Next week, we'll be talking about something completely different, and hopefully welcome news to those who have been wondering what's happening with that 64-bit support we were talking about earlier in the year.

Classic Jake. Telling us he's going to talk about some 64-bit support, and then they drop that big Qing teaser

He meant the 64 bits that Ming breaks into... obviously.
 
Wouldn't it be good for the cardinals that converted Christian Nations (historicaly) would get Events if they have good papal relations (like congo and maybe Japan if converted) to get a cardinals via event? (send the Pope some ivory f. Ex. / money and the Pope gets an Event to exept and give them a cardinal) - also some Events for the Pope to bribe him for giving a cardinal would be historic correct and would add much flavor for the Pope and the Nations that would been given the event?
 
While it likely won't be a tag switch, I do desire "Kingdom of God" actually being seen on the map.



Curia Controler will still be chance-based from papal investment and Cardinals



Once a Papal Bull is enacted, it will last until the death of the current Pope, which will also trigger the next Curia controller.



The nation-specific actions bought with Papal Influence will still exist.



It'll be up to @neondt when we show off the hefty Papal Tree, but there are more mechanics to cover before then.



Features shown in this Dev Diary are going to be paid content in the upcoming European Expansion.



Indeed.



We are unsatisfied with the AI's ability to convert, particularly subjects. This is a high priority for fixing in the update.



Without making Rome / the Curia Controller a pinata, we do want to have some sweet sackings of the Tithe.

Here are some humble ideas:
1) "The Pope always supports true Catholic rulers who take upon themselves the task of punishing the enemies of the Church". Thus if:
- player is Catholic,
- at war against an excommunicated/heretic ruler,
- has +100 relations with Papal States,
an event has a chance to happen, giving the player two choices:
a) "We need money to pay the soldiery"
- get 15% of its yearly income from Papal tithe (provided there's enough money there), or
b) "We need the peasantry to enlist in the army"
- get 3% Crown Lands currently held by the Clergy.
- get manpower equal to 100% yearly manpower recovery.

2) "The Pope is keen on rulers who put their efforts in redirecting its flock back to the teachings of the Holy Church". Thus if:
- player has embraced the Counter Reformation,
- has converted 20 provinces from a heretic denomination to Catholic,
- has +50 relation with Papal States,
an event has a chance to happen, giving the player 15% of its yearly income, taken from the Papal tithe (provided there's enough money there).

3) "In 1527 Rome was sacked by mercenary troops serving in the Imperial army of Charles V. This was the city's seventh sack since the Dark Ages. Any army capable, both in strength and spirit, to plunder the Eternal City, may leave with great riches, as well as the Pope's wrath". Thus if:
- player is at war with the Papal State,
- player controls Rome,
- Rome has at least 50 devastation,
an event happens, giving the player two options:
a) Let's take it!
- -5% army professionalism,
- get 25% of the Papal tithe,
- the Papal State gets the opinion modifier "The Sack of Rome" towards the player for 50 years, worth -100 opinion with a yearly decay of 2.
b) The Papal Seat is worth reverence, not plunder!
- +2,5% army professionalism.
- +2,5% discipline for 10 years.

4) "The faithful also have the duty of providing for the material needs of the Church, each according to his own abilities". Thus if:
- player is Catholic,
an event has a chance to happen, giving the player three options:
a) "Contribute directly to the Papal tithe"
- transfer 10% yearly income to the Papal tithe
b) "Contribute to our national Church instead"
- transfer 3% Crown Land to the Clergy
c) "The Church has its own resources"
- the Papal State gets the opinion modifier "Ruler refuses to pay the tithe" towards the player for 10 years, worth -50 opinion with a yearly decay of 2.5.

Also, perhaps:

5) "The Holy Father has attentively observed your latest actions, and he is convinced you can be readmitted into the Church... for a price". Thus if:
- ruler is excommunicated,
- is at peace with the Papal State,
- does not have a truce with the Papal State,
an event has a chance to happen, giving three options:
a) "Let's donate to the Papal tithe to show our loyalty!"
- transfer 50% yearly income to the Papal tithe
- excommunication is lifted
b) "Our local Church has guided us towards a renew communion"
- transfer 7% Crown Land to the Clergy
- excommunication is lifted
c) "We do not seek forgiveness from this Pope!"
- Catholicism gains 1% reform desire
 
In the Europe update, will Catholic nations get new abilities to combat the reformation?

At present, the state edict "Religion Enforced" serves as a good bulwark against centers of reformation. But there remains a couple problems that make the Reformation extremely frustrating to deal with, (but not in a fun way).

First problem: unable to halt or slow conversion of provinces that have been targeted by a center of reformation. Once that conversion bar starts ticking, it's inevitable. And it feels kinda sucky that you can't do anything about it. Worse, you end up flipping the province back and forth: convert, reconvert, convert, etc. That gets tedious. Possible solution: enable missionaries to combat reformation. This could come down to a duel of religious influence, which would be neat. If Catholicism is too weak, it may just mean slowing down conversion. And if Catholic nations don't have many missionaries, they still might can swamped from multiple centers of reformation converting them. But it would prevent reformation from being OP, and at least give the player the feeling that they can do something, even if that's just spitting in the winds of change.

Second problem: unable to stamp out centers of conversion. As far as I know, the only way to end a center of conversion is to make sure the host nation is dwindled down to the point that the center is in their capital, and then force converting them in a war. That's very particular. If, instead, you take the center as your own province after a war, weirdly enough, there's nothing you can do to stop it. You can't round up the zealots and execute them. I don't think you can expel them to the New World. You're just stuck with them. Possible solution: some sort of military "routing out zealots" action, that would come with a big cost and big a malus. Something severe enough to make you pause and consider if it's worth it. Perhaps extreme unrest and a large loss of development, together with a diplomatic penalty with reformed nations. Or really anything that would give you some tools against this weirdly unstoppable menace.

To be clear, I really like how the whole Reformation period works. It's challenging and unpredictable, which is fun. But I don't enjoy feeling like there's nothing I can do against it. ("Why not just convert to Protestantism?" isn't really a good response).
 
we all agree that the catholic faith needs an update, specially since you have strenghtened all the religions. those are some interesting ideas however is not of the many player interests. here are some suggestions that should be added:

First: do you know what catholic means?. catholic or universal is christianity that recognizes the pope as head and succesor designated by jesus himself, if you search a bit you should find a lot of churches that does it not only the latin roman church. thats stated by both concils vatican 1 and 2. my suggestion should be that every chirstian religion should have the ability to make use of the curia mechanics as long as they recognize the pope authority by some event or prerequisites, i'd leave that to your imagination.

Player are satisfied with bonuses the curia gives, sure is quite expensive but worth to get. The main concern is since you streghtened other countries and added a whole lot of new provinces, catholics have struggled to convert that many provinces speacially to get the one faith achievement. I mean ,come on, is the most organized powerful and most widespread religion of the time but it doent have conversion ideas. A 1+ missionary from curia controler and 2% missionary strenght from curia edicts should be sufficient instead of blowing yourselves trying a whole new system. hre is fine no need for boost through the curia, it also would help the ai be more likely to try at last to convert.

regarding the italian region. once the protestant reformation starts. it's really powerful sometimes if the playes doent intervene it could convert half of europe. No complains of that ofc, it makes the gameplay different and interesting. however the protestants take ahold of all the hre and go straight to convert the popes backyard, even rome itself? there was a meeting between italians during the age of rev. and after napoleon where all the italian neighbors had already consolidated their region, and the first suggestion was they should unite but with vatican as head. that and the kingdom of god should be parallel. for example once the hre falls under heresy the italians should get an event to unite under the pope. nake that choice optional ofc.

Make jerusalem west and give them the hospitalers unit model but white.

finally, it is interesting that you added the mechanic to convert trade companies with only trade power but only for muslims, thats too bad i mean the way christianity spread was through trade. im not saying that the christians should have the same mechanic too, if you say the muslims should be the most powerful in the game cuz of sweden current state idc. at least add some events like protestants random 1 province convertion on catholic soil, 1 random christian faith spread in 1 province on other heathen contries once they discover the west, so the player at least can convert through revels if choose. it would also help if any country with high enough development could get a cardinal and curia control. Make that a thing DEUS VULT!. thanks
