CK2 Dev Diary#26: Considerable Converter Capabilities

Hello all, and welcome back to another CK2 Development Diary. If you didn’t notice last week, we now do CK DDs on Mondays to match up with the Medieval Monday stream. Anyway, getting on to the point of this DD: We’ve been updating the Converter!

Development in EU4 will now be based on the state of the world in CK2. Holdings, Buildings, Hospitals and Prosperity all count when determining if your capital should be the new Paris or not. The development of the default 1444 EU4 provinces (within the converted area) will be redistributed in a way that makes sense for your world.

Dynamic fort placement. No longer will forts be placed exactly as they were in the default 1444 setup, instead forts will be placed in strategically appropriate areas for each nation.

Revamped Tech Groups. Now, as Tech Group no longer actually affect your technology cost (that’s handled by institutions), your group will be based on the geographical area of your capital. This is then used to improve your experience in many ways, i.e. through custom idea generation!

Dynamic ideas. No longer will your nation simply have the ‘National Ideas’ set, instead a unique one will be generated for you based on your situation in EU4. These idea sets will give you appropriate ideas, so no naval ideas if you are landlocked or just have one port.

Institutions have been revamped to account for the vastly different world that is a converted game. The institutions will spread in a much more dynamic way, and no longer discriminates in favor of Europe (especially not if India or the Middle East manage to get a high Development converted over!). Institutions such as the Printing Press do not necessarily have to spawn in Germany, either.

Converter-centric idea picking for the AI. With most converted games missing a Portugal, and in some cases even a Castille or England, the AI has been readjusted to dynamically assume these positions. One nation will try to assume the role of Portugal - be it Iceland, Scotland, Korea or Majapahit you won’t know until you play!

Traits now convert over from CK2. Did you have a midas touched genius ruler or a possessed imbecile lunatic ruler? No matter what, you will recognize them by their traits in EU4.

Improved Sunset Invasion setup. For all of you who wanted the New world empires to be even mightier we’ve improved the High Americans with new missions and unique units. High American units tend to have many Fire pips, so beware their power!

The Converter will be updated alongside the release of Rights of Man on the 11th. That’s all for now, but I have even more Converter stuff to talk about next week.

What would happen if i had in kiev 5 maxed out towns a maxed out castle and church, with prosperity 3? what's the development floor?
I think it is all relative. The best provinces in CKII will become the level of the best provinces in EUIV, and the worst become the worst.
This is exactly it. We sort all EU4 provinces by their development, then sort all CK2 provinces by their pseudo-development (the mentioned value), and we give each CK2 province the develoment of the province of the same rank in EU4.
So if say Kernev was a megalopolis with all 7 settlements filled to brink, plus an hospital also filled to the brink, a trade post and prosperity 3, Kernev in EU4 would receive the development of Constantinople (or Paris).
This way the map stays balanced, but the most developed area of CK2 are also the most developed areas of the converted game.

How much can the converter be modded? And can we mod EU4 to fit new personality traits?

(I've never been a modder... ...but... ...way of life dlc... ...reaper dlc... even short of immortals, evil thoughts abound...)
A lot of the converter can be modded, it is one of the way we encourage people to improve the conversion to fit more with their vision of what it should be.
To answer the specific question, the personality trait conversion can be modded to add more or remove those you don't like.

Speaking of 2.6.2 have you then solved the speed problem? And if not will you then allow people to stay on 2.6.1 if they prefer having speed?
We have found the issue, and a branch should be available.

Now if we could just get an official EU4-V2 converter, I'll be happy (not knocking the mod, I'd just like an official one).
You obviously lack the 'Ambition' trait. I'm waiting for the EU4->V3 converter... ;)

I absolutely can't wait for this, and hope you'd be willing to answer a question. If you convert the same save multiple times, wil the ideas be the same each time? And what factors into the ideas: a combination of culture, religion, and land owned?
 
@Moah So, if you don't have Reaper's Due, (or any future DLC that adds extra province stuff), what happens? will your provinces be poorer on average or will you have different values for that?

if you don't have RIP, the "ck2 dev" is lower than if you had rip, but it doesn't matter because the most "developed" province from ck2 will still get the development values from the most developed province from eu4 (ie your highest ck2 province has a value of 17 instead of 21 let's say, it still gets constantinople's development).
The "ck2 dev" only matters in relation to other ck2 provinces, and only for sorting provinces from richest to poorest.

I don't understand, so if Portugal doesn't exist another nation will try to become the 'early game colonizer', but Korea isn't even affected by the conversion, and not at all suited for colonizing northwest Africa or Brazil, so how does this work?
It's highly dependent on where the renaissance spawns - if it spawns in Asia then an Asian country till assume the role of Portugal (unless you as the player does it first), European nations suitable for colonization will colonize too, of course. In my test game Korea reached America by going Taiwan -> Micronesian islands -> Hawaii -> California, an alternate and fairly exciting route. I also had a game where a converted India went Ceylon -> Andamans -> Philippines -> Micronesian Islands -> Hawaii -> California and a game where the united Japan went directly for Alaska -> California!

Great stuff, time to finnish my current CK2 game in time for the Rights of Man release, just two things:
  • No naval ideas for nations with one port excludes one province minors, right? Else it wouldn't make sense for a Socotra or Gotland that is independent at the time of conversion.
  • Will the Sunset Invasion setup work with a EU4 Random New World, I don't recall if it currently does but I think I remember it doesn't.
Merchant republics and OPM's with a port will probably be weighted up for naval ideas, it's all fully scriptable and moddable too.
The Sunset Invasion setup doesn't support RNW.

Can we count on improvements for converted heresy? Eg. Karma system for the Cathars or Fervor system for Iconoclasm in EU4?
All religions should have something exciting, most of them make use of Fervor or Aspects though.

This kind of worries me, actually. Usually, I find in my CKII games that most provinces everywhere get developed about the same amount. Perhaps the player's area is more developed, perhaps certain AI areas are underdeveloped due to frequent changing of hands. But I worry that all converted games are going to look the same, and, unlike the current system that uses vanilla EUIV development, the converted developmen will just be evenly spread everywhere, with no especially rich or poor areas.
The only consistently different area compared with the default 1444 setup is Arabia. It's generally more developed, as it's much more unlikely for them to get absolutely stomped by Mongols in CK2 than happened historically. In general Scandinavia and Russia are very poor, without player involvement. The setup varies a lot between game to game though, I just finished a game where I got Kola to get Paris's development and Finnmark to get London's! Getting high EU4 development is a really fun sub-goal to aim for in your CK2 games.

You can mod a lot of it! I would even dare say most of it.

Ok, that's rather cool. However would it be possible to force the 'Portugal' to appear in Europe for when one doesn't want a too funky game, apart from portugaling yourself.
And if Portugal does exist (be it in the form of a Muslim Sultanate), are they certain to take the Portugal role?

Does this account for things like having been recently raided lowering both the taxes of holdng and the general prosperity? (Are we going to see a thing where provinces which were recently raided before conversion get lower development than they should have, for example?)

Edit: also what about cultures? Does the converter break up cultures like French and German now?

If it isn't a bother can you say what was the issue? Curious about what was making such a huge difference.

We want converted games to be more open and 'fair', so there's no way to force it. You can easily mod it though.
They will pick early Exploration ideas, so unless they're crushed by war they should explore & colonize early on.

Thank you so much for these improvements! Have you done anything about some nation conversion oddities such as CK Norway not converting to EU4 Norway?

And I also have a few extra suggestions. Would it be possible to make some EU4 tags fordable such as England for Anglo-Saxons if England does not exist? Also, would it be possible for Muslim and Hindu nations to convert their CK2 CoA to be their EU4 flag rather then the title's christian flag?
I believe you CAN form England in a converter game as Anglo-Saxon, though I might be mistaken.

But Asia is (except for India and the middle east) not converted along, which is why I asked as it makes no sense that Ryukyu becomes a worldly colonizer because Portugal doesn't exist half a world ago :/
Guess I'll mod it though...

The Constantinople reference has me a little nervous as it doesn't start with fantastic development like Paris, London, Beijing (if I recall correctly), Milan, or Rome unless the Ottomans or Byzantium take their special decisions.
 
Woo hoo! The converter is the best!

That's what I get for having been a CK2 exclusive for so long: i keep thinking in those terms. Thankfully the code doesn't look at the values I think province have, but what they actually have, so it should be all right.
Just a note: Beijing should not be in the running, since we're only redistributing the provinces that have a CK2 equivalent.
