CK2 Dev Diary #83 - God Wills It!

Greetings!

PDXCon is soon upon us, and we hope to see you there! During the event we will reveal the name and theme of the Expansion we’re working on, and after PDXCon is over we’ll have plenty of Dev Diaries that will delve deep into the new expansion features. For now though we’d like to present the main feature of the free patch that’ll accompany the Expansion!

It is time to don your armor and ready your steed, as the Vicar of Christ himself has declared that all who join in expelling the infidel from the Holy Land will have their sins absolved!

The Crusades are a very iconic part of the game, though one that has barely seen any change since the game was released 6 years ago. A lot of fantastic and interesting systems have been added to the game over the years, and we wanted this very central feature to feel as deep and interesting as any one of them.

The Catholic faith will no longer use the old Great Holy War system - instead they will use a new and improved system specifically tailored to both increase immersion and enhance the gameplay surrounding the crusades. This system is massive, and it might be hard for us to fit all of the information into this single DD, but we’ll give it our best shot!

We have specifically aimed to fix the issue where, unless you intend to win the crusade, there was no real reason for you as a player to participate except to get the ‘Crusader’ trait.

To accomplish this we’ve made Catholic crusades work in two phases; first there is a Preparation Phase, followed by the actual war. To communicate this properly we needed a new dedicated interface. Enter, the Crusade View:

CrusadeDD_PrepPhase.png

Holy shield, on the wall, which is the holiest city of them all?

When the pope decides that it's time for a new Crusade, he will send a call to the Catholic world for support. When he does you can access the Crusade View by clicking the Crusade Banner underneath your portrait.

In the Crusade View you will have access to a plethora of useful information, and you’ll be able to take actions to help the crusade or to alter its course. You will be able to see the Pope’s proposed recipient (if any) in the top left corner, and the target character and title in the top right. There will be a timer counting down to the date where the war will start. During this time, the following can be done:
  • Catholic rulers can pledge their military support to the crusade. When they do, they appear in the list of Pledged Participants. For every crusader that pledges, prestige, piety and artifacts are added to the War Chest. The religion being targeted by the crusade can ‘counter pledge’, and it’s the relative strength of these two sides that is shown as ‘Total Strength’ underneath their portraits. Pledged rulers will automatically be called into the war as it starts.
  • All Catholic rulers get the option of donating money to the War Chest in exchange for piety and opinion with the Pope. This money is then added to the War Chest, more on that later.
  • Crusaders who have pledged military support can add a beneficiary to the crusade. This character must be a dynasty member, and depending on your participation in the crusade they might be granted a title in the Crusader Kingdom should the crusade be successful. More on this later.
  • Players can pay piety to change the target character and/or title. This cost starts fairly low, but doubles each time to avoid spamming. This means that if you’d rather have a crusade target a scary infidel realm on your immediate border, you can make it happen if you’re pious enough!
  • Players can choose their ‘Stance’ on what they want to happen should they be the most participating crusader. More on this later.

If a Catholic ruler chooses to neither pledge to the crusade or donate money to the War Chest, the Pope might get very upset with them. Depending on the rulers tier and influence, this can range from a simple piety hit to an outright excommunication. Revoking your pledge also carries a similar penalty.

Regarding the War Chest - when the preparation phase is over, 20% of the money in the War Chest will be divided between the pledged Crusaders, in order to provide for their levies and fleets as they go to war. The rest is saved until the end of the Crusade, where it is used as rewards for the participants and to set up the Crusader Kingdom. The Crusader Kingdom will receive 10% of the War Chest in order to steel them against imminent counterattacks. The rest (including prestige, piety and artifacts) is given out to the Crusaders who participated in the crusade, in order to motivate you as the player to participate as much as you can - even if you don’t expect to win. To ensure that the top contributors don't take all of the War Chest rewards, any one participant can receive at most 20% of it. As the Catholic world tends to be rather… generous with their donations, this often translates into a lot of wealth! Beware though, if the crusade is lost the majority of the contents of the War Chest will be lost, and Christendom will be weaker for it...

When the Preparation Phase is over, the war begins and the Crusade View changes:

Note that the numbers are still WIP.

The Countdown Timer is replaced by the warscore and the name of the Crusade is updated, otherwise the functionality remains the same (except for being able to change the target, of course, at this point it’s too late for that).

If the Crusade is successful, what will happen depends on the top contributor’s stance. There are three stances; ‘Selfish’, ‘For my Beneficiary’ and ‘Comply with Papal Demands’. The AI will always choose to go with Papal Demands.
  • The ‘Selfish’ stance will see the top contributor take the lands for themselves. Doing this completely disqualifies them from the War Chest though, and is seen as impious by the Pope.
  • The ‘For my Beneficiary’ stance will see your beneficiary become King/Queen of the lands. While still not approved by the Pope, it’s not seen as impious, and you still qualify for (parts) of the War Chest. If the pope has chosen no recipient for the title, this is the default behaviour and carries no penalties.
  • The ‘Comply with Papal Demands’ stance simply sees whoever the Pope wishes to rule the lands become the King or Queen. If he has no opinion, it will go to the top contributor’s beneficiary.

In the old system, the title and all under it went to the winner of the crusade. You often saw France or the HRE own for example Jerusalem, which in all honesty was very boring, and more often than not only resulted in an inheritance mess. While a player can still choose to use the old system by choosing the ‘Selfish’ stance, the new default behaviour is completely different. Unless the Pope wishes to restore an existing King or Claimant (where the normal, old, behaviour will be used) a Crusader Kingdom will be set up:

CrusadeDD_JerusalemAllSetUp.png


A Crusader Kingdom is a multicultural kingdom made up of the beneficiaries of all participants. The top contributing participants will have their beneficiaries get higher titles in the target kingdom. To avoid the player gaming the system using inheritance, the Kingdom is always set up to disallow external inheritance - and the AI tends to choose beneficiaries that do not stand to inherit or are married to someone who might inherit.

If your beneficiary receives land in a Crusader Kingdom, your entire Dynasty will receive a monthly boon to piety until their death. In a future Dev Diary we will go into more detail regarding the importance of Piety in the Catholic sphere, but rest assured that it’s going to be more important to be seen as pious than it’s ever been before - making the boon from your beneficiary rather significant.

The new ruler of the Crusader State, in order to properly rule such a challenging realm, gets a trait appropriately named ‘Crusader King/Queen’ which confers a massive same religion opinion along with some other goodies.

And, for the finale, if your beneficiary is selected to be the King or Queen of the Kingdom - you have the option of switching over to them, taking control of the newly established Crusader Kingdom and leaving your old character behind (which is also part of the reason why you can only choose members of your own dynasty as beneficiaries). We believe that doing a thing such as this will provide the quintessential CK2 experience, where you have to both manage unruly vassals and defend against vengeful religious foes!

Stay tuned for future Dev Diaries, where we might go into detail on a few… special crusades.
 
I know I was just meaning it doesn't need a own western crusader culture.

It's actually different. Andalusian was Romance ruled by Muslims. A crusader culture would be Romance ruling Iberian Muslims (Berber, Arabs, Mozarabs etc)

Well, *probably* Romance/Latin. It could be Germanic groupings if English is around and they over perform, or the HRE gets enthusiastic about Crusading. It could even be Slavs or Greeks or Russians.
 
Regarding the "crusader culture" discussion, I am not so sure it would be something that would be particularly easy to implement.

Sure, if you get very historical crusades (e.g. Sunni (?) Levantine Jerusalem taken over by French/Norman lords), then you could probably figure out a reasonable "crusader culture" that could spring up, but CK2 history often goes widely off the rails, and if the crusade was launched to take over the Buddhist Norwegian kingdom of Cumania and the crusader kingdom is made up of Greek, Han, Sepharadic, and Croatian rulers, what should the resulting "crusader culture" be like?

Religions can already have specific names associated with them, so the Buddhism part works regardless of culture.
For the rest, you can pick the following cultures to work with:
  • the native culture of the capital of the new kingdom
  • the culture of the crusader king/queen
  • the culture of the plurality of title-holders (count or above)
You weigh those at 50%, 25%, 25%, and make a new name list in those proportions from the three cultures.
With cultural bonuses, again, mix them up in those proportions.
With title/job localisations, just stick with default (English).
The name of the new culture will be <Culture1_adj>-<Culture2_ad>j-<Culture3_adj>
 
It's certainly not easy.

If they were going to do it, I'd think they'd be safe starting with something based on the likely outcomes.

Latin, Germanic (including English and Anglo-Saxon), Russian, or Greek crusaders conquering Levantine, Andalusian, or Baltic lands (I think those are the most likely non-Christian areas for a Crusade).

Russia conquering the Baltics is fairly simple. For the sake of sanity it all collapses to Russian eventually. If the Germans take the Baltics, it probably collapses into German.

Latins taking Levantine areas, probably forms the Outremer culture as mentioned earlier, with cultural units based around cavalry (because knights) or pike (because Italians).

Germanics taking Levantine, probably and boringly creates Outremer as well.

With Russians, it's a little harder to guess at.

Latins taking Andalusian territory should probably try and adjust to something like Castillian or Catalan. It's *mostly* historically sensible.

Not sure 100% for any of the other combinations.


Conjoined adjectives would get clumsy. Andalusian-Sephardic-Russian wouldn't look good on the map... It'd be evan worse if they went on to be the dominant culture in a future crusade, and you now have Letgallian-Andalusian-Sephardic-Russian-Greek as your cultural adjective. It'd be far easier and cleaner looking to create a plausible looking crusader culture name for the likely combinations, and default to whatever the closest usually Catholic group combined with the normally present non-Catholic group would be. So Latin/Levantine producing Outremer might be the default if there isn't a specific entry for the combination found in game, whereas if you cant find something in Spain, Crusader/Andalusian will move towards Castillian in the middle, Portugese in the west, and Catalan in the east (and then be subject to the usual changes).

Dynamically creating the name list is good though. I like that idea provided that "inappropriate" names could be filtered out (Mohammed I, King-Archbishop of Jerusalem seems a little odd somehow).

Cultural bonuses would be difficult. Some bonuses are much stronger than others, and I'd be tempted to have it inherit as much as possible from the conquest culture (either the monarch or the dominant culture amongst the nobles). However it is done, it'd need to avoid creating a culture that takes the best qualities of several cultures.
 
For the crusader culture I would suggest a simpler approach.
The name of the crusader culture should be the adjective form of one of the duchies / counties of the crusader kingdom. The reason being it would look strange e.g. for the Kingdom of Jerusalem to have "Jerusalemite" culture, but let's say "Galilean" or something similar works better.
For cases that actually existed exceptions can be defined - e.g. a Frankish / French crusader kingdom in the Levant would shift to "Outremer".

The culture group should be tied to the culture of either the winner of the crusade or that of the winner's beneficiary, if the two are different.
Although there might be a mish-mash of cultures among the counts, dukes, etc, one can assume that the majority of the new "ruling class" is of the same culture as the crusade winner - he was the one to contribute the most in the war, after all. Alternatively it can also be assumed that the King's culture is something to which the new nobility would have to adapt to, not the other way around, at least to an extent that the emerging crusader culture resembles other cultures of the King's culture group.

Unfortunately this logic does not resolve the case when the culture group of the King and that of the crusade winner (if different from the beneficiary) differ. I guess one of the assumptions above must be picked.
 
How will the decision to vassalize the Templar and Hospitallers work now? I have to choose the selfish option during the first crusade?
Probably works the same as before.

I mean, looking at the decision,
Code:
potential = {
    is_playable = yes
          
    OR = {
        religion = catholic
        religion = cathar
        religion = fraticelli
        religion = waldensian
        religion = lollard
    }
    is_heretic = no
          
    NOT = { has_character_modifier = expelled_d_knights_templar }
          
    is_title_active = d_knights_templar
          
    has_landed_title = k_jerusalem
          
    has_dlc = "Sons of Abraham"
          
    d_knights_templar = {
        holder_scope = {
            NOT = { has_truce = ROOT }
            ROOT = { NOT = { has_truce = PREV } }
            liege = {
                NOT = { character = ROOT }
            }
            NOT = { num_of_count_titles = 3 }
            independent = yes
            primary_title = { title = d_knights_templar }
        }
    }
}
      
allow = {
    wealth = 500
}
if you don't get the Holy Orders under you, you can just take over Jerusalem yourself, give yourself the kingdom, and as long as their former liege is no longer a king or emperor, vassalize them yourself.
 
Religions can already have specific names associated with them, so the Buddhism part works regardless of culture.
For the rest, you can pick the following cultures to work with:
  • the native culture of the capital of the new kingdom
  • the culture of the crusader king/queen
  • the culture of the plurality of title-holders (count or above)
You weigh those at 50%, 25%, 25%, and make a new name list in those proportions from the three cultures.
With cultural bonuses, again, mix them up in those proportions.
With title/job localisations, just stick with default (English).
The name of the new culture will be <Culture1_adj>-<Culture2_ad>j-<Culture3_adj>

That would result in unrealistic name lists. Like Having Welf and Guillaume and Henry and Wahid on the same name list. All of this names don't fit together by spelling (Guillaume is only spelled with Gu- because French people have problems with W- so Welf would only ft if it was written Guelf etc). A mix of names just looks ugly. Especially if it would result in somethink like Guillaume and Sigfrøðr on the same list.
 
Let also add "New" Prussian while we are at it.
Prussian(Baltic) would flip to Prussian(Central Germanic) as a melting pot. Would require Old Prussian provinces ruled by a Germanic ruler.

The entire German blob could use a breaking. Maybe separate the lower Germans (Saxony etc) from the higher Germans (Bavaria etc)?
 
I’m going to assume that the new Crusade mechanic where you can request a beneficiary is in the unreleased expansion?

I’ve seen the request Crusade button which I assume is new.
 
Everything in this dev diary is free.
The request Crusade has been there for quite some time, since Sons of Abraham I think? When the GHW unlocking was reworked

That’s pretty interesting. I’m surprised I’m finding this mechanic out now after all this time. Though my issue is...the image on the first page showing the new Crusade screen, I don’t see it or experience any preparation phase.

Wondering if I’m doing something wrong or the patch hasn’t added it in yet.
 
Here are the requirements for requesting a GHW

For the preparation phase, you mean in your current game? That's because it'll be in the next big patch, probably a few months away

Yeah, that was one of the issues I was thinking of, and with cultural features that aren't just numbers thrown into the mix you'd possibly end up with stuff like the Han surname first feature or the Andalusian dynasty title names thrown into the mix or very powerful combinations due to sheer random luck (e.g. horde culture + seafaring + raider), or the like.

Clearly Dev Diaries show old mechanics that are already out.
