EU4 - Development Diary - 14th of March 2017

Good day everyone, it's another bright and sunny day in glorious Stockholm, or rather, I wish it were. To distract from the grim grey reality of this cursed latitude let's delve into the second Religious overhaul present in Mandate of Heaven: Shintoism.

One month ago we got a Dev Diary covering changes to the Governance of Japan. As many of you I'm sure are aware, we model Japan with the strong but mechanically lacking Shinto religion. Shinto belongs in the Eastern religion group and are eligible to compete for the Celestial Throne and as part of Mandate of Heaven, Shinto nations will also have their own Isolationism mechanic.

Shinto nations will have an Isolationism level, 5 stages from Open Doors to Closed Doors each giving their own national effect. Japan starts in 1444 under the Ashikaga Shogunate before their Sakoku period of Isolation and as such is at an "adaptive" level. Periodically, this Isolationism level will be challenged by Incidents. Up to 8 of these Incidents can trigger throughout a campaign, depending on the situation in and around Japan.

Each incident can fire once per campaign and are spaced out by at least 30 years. They will spawn events giving choices on the issues they present in the vein of accepting new ideas, goods and people in Japan. Depending on how you react to these choices, your Isolationism level may draw closer towards open doors or closing off from the world as well as a 50-year modifier to your nation at the end of each Incident's event chain. Which path you wish to take is up to you and how you wish to shape your nation.

Isolationism level bonuses:

Open Doors
technology_cost = -0.05
embracement_cost = -0.1​
Adaptive
global_institution_spread = 0.1
development_cost = -0.1​
Selective Integration
idea_cost = -0.1
build_cost = -0.10​
Isolationism
culture_conversion_cost = -0.15
missionaries = 1​
Closed Doors
war_exhaustion = -0.03
stability_cost_modifier = -0.15​

Each Shinto nation will face these Incidents independently but the mechanic does not exist in a vacuum for each nation. The Shogun will gain a bonus to prestige for each Daimyo who has the same level of Isolationism as they do and conversely, suffer for each who does not. The Shogun has the power to force their subjects closer towards their own Isolationism level but at a great cost to their Liberty Desire.

the 8 Incidents in the game are:

  • Shushi-Gaku Neo-Confucianism
  • Nanban Trade
  • Proliferation of Firearms
  • Spread of Christianity
  • Rising Shogun Authority
  • Ikko Ikki
  • Wokou Pirates
  • Urbanization
Since each have their own triggers, it's not a given you will see all 8 if, for example, you do not get a port for Wokou Pirates or Christianity is wiped clean off the map preventing its spread.

Exciting stuff, but I want to take this opportunity to look at Japan itself too. We have spiced up Japan with map changes, new provinces and many new nation tags in the Islands, as well as re-writing a lot of the old existing events for the Japanese. Additionally, we have given unique National Ideas to all starting 1444 Japanese nations to stand in line with our goal of revitalizing the region. I'd like to extend a thank-you to community members @chatnoir17 and @Grand Historian for their extensive contributions towards these. Suggestions are always appreciated towards the development of our games.

I'll share just a few of these Idea Groups with you who enjoy reading our script files:

    }
 
    tti_kofukuji_temple = {
        idea_cost = -0.1
    }
}

Map Changes, new nations and new National Ideas are all free parts of the 1.20 update, while all things Isolation related are paid feature of the upcoming Mandate of Heaven Expansion, which releases for $19.99 on April 6th 2017

That wraps up Japan and Shintoism nicely, and next week we will be talking about an extremely exciting feature which is going to truly make your Diplomats work for their non-existent salaries. See you then!

Will we be able to play Oda at 1444 :(

I doubt it if they don't have NIs. But there are plenty of clans just as interesting and less known as the Oda to play as.
 
Cool, so if you go Isolationist, you get bonuses for playstyles that would require you to be the opposite of Isolationist.

We wont be able the dev confirmed that befor when i asked. So hope for a mod or that they become a formable tag.
@Grand Historian you seem to know a lot about Japanense History. In 1444 there is a other Clan on the Map area where Oda is in the later game. Since when Oda became more Important in this region ? And would you think to have them as event nation for ai or formable nation is a possiblity? even this wont really reflect the real history.

Oda were retainers of the Shiba clan in Owari province. There were several cadet branches of Oda and took the de facto control of the province after the Onin War (1467-1477), but we have to wait for Oda Nobuhide (1510-1551, father of Nobunaga) as ruler of "EU4 level province". Although it was Nobunaga who literally united the province, and it happened around the Battle of Okehazana (1560).

The Oda were present in Owari in 1444 - in fact, excepting the Ikeda and Maeda, all the Daimyo who get cores on provinces later were actually present in their provinces at start, just not as dominant landholders (for example, Mori only had Takata Gun in Aki in 1444). The Shiba clan were the main power in Owari Province in 1444 with the many Oda branch families acting as their retainers there, though the Oda wouldn't actually become dominant in the province until the Shiba Civil War that coincided during the Onin (in which they were one of the main instigators of the former - this was also how the Asakura clan of Echizen rose to power). However, it wouldn't be until Nobunaga's father, Nobuhide Oda - the Tiger of Owari - rose to leadership of the Nagoya Oda branch that the Oda actually eclipsed the Shiba in real power, invading Mikawa and growing wealthy from trade. Even still, the Oda officially wouldn't break free of the Shiba - or, rather, the other branch of the Oda that were puppeting the Shiba - until Nobunaga's rise to power.

I don't think having them as an event or formable would be feasible or sensible, even in spite of Nobunaga's immense popularity; simply giving the later daimyo tags cores on their starting provinces should suffice for those who want to play as them.
 
@Trin Tragula

Are there any territorial or changes of any sort in the Balkans as part of the upcoming free update?

It's been confirmed elsewhere that there are no map changes to the Balkans or Europe as a whole this time around.
 
Still don't understand what shintoism has to do with migration policy, but I'll just roll with it for now ¯\_(ツ)_/¯

I wonder how difficult it would be to mod it so that migration policy is separated from Shintoism. The real question, of course, is where to put migration policy under. Government tab in Country view, perhaps? Another issue is that removing migration policy would probably gut Shintoism considerably unless we replace it with another mechanic, possibly from another religion, to make embracing Shintoism as a religion viable.

Anyway, that is just me thinking as a modder. Naturally, this would not work for anyone who want to play for achievements as modding of this kind alters the checksum.

To be fair, a new interface specifically for policy making would be a nice edition, kind of like the Modern day mod for hoi4. A section where you could decide national policy. Like, if you wanted to have high immigration, or low. If want to have stern penal laws or not etc etc. I know the nation state is still kind of in the making, and migration is still probably pretty rare (I actually don't have a lot of information about this timeframe concerning that), but it would nevertheless be a nice addition for the modding community. I know that this was probably not what they were trying to achieve, but to me it looks like migration policy, so. . . ;/
 
So does Neo-Confucianism introduce Confucianism, like the Ikko-Ikki and Kirishitan introduce Mahayana/Catholicism?

EDIT: Also, will there be any reason to keep Catholicism as Japan, instead of dropping it immediately for Protestantism/Reformed?
