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.

eu4_154.jpg


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.

eu4_153.jpg


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​


eu4_152.jpg


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:

}

    }
 
    bonus = {

        prestige = 1
    }
 
    tti_mountainous_province = {
        hostile_attrition = 1
    }
 
    tti_nara_city = {
        legitimacy = 1
    }
 
    tti_wise_opportunist = {
        ae_impact = -0.1
    }
 
    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!

Selective Integration looks like the most powerful bonus since counting on institution spread has been so far extremely unreliable. At least with -10% idea cost you're guaranteed to save a lot of points which can in turn lead to province development.

The closed doors bonus is okay too.

But what I like the most is the events being rewritten and new national ideas for every 1444 daimyo. They should make playing in Japan a fun experience with idea variety and (hopefully) no poorly thought out crippling events.

The isolationism bonuses seems a bit lackluster for something as important a part of the country? Also, wouldn't it be cooler if you also had negatives? (Like revolt risk, stability cost, institution spread, trade power abroad, diplomatic reputation, etc.)

I hope you didn't change Japanese (formable) ideas! While they are not the most historically accurate, they are still FUN!

We did change them. Some have gone to Ashikaga but in general the changes for the Japanese formable ideas have been strengthened now that there is much greater variety in what you can have beforehand.

Will these incidents have significant effects on their own, beyond just changing Isolationism levels? All I see here is a 10 year modifier, but I understand it's actually a chain of multiple events?

Also, how does this interact with countries that are Shinto, but not the shogun or Daimyo? Similarly, does it matter as the shogun if for example one of your Daimyos becomes Christian?

What's that strange looking alert with the glowing head?
I believe that was an alert signifying you have enough splendor to buy a new ability?

At the end of the chains you get a modifier for 50 years dependent on your choices as well.

For both the Ikko Ikki and the Christianity incident the extreme versions of the end will not see your state religion officially changing (as that would remove the incidents and japanese mechanics), it is just seen as you giving this religon a favored status above the others.
If you do eventually form Japan however you will then be able to make Christianity or Buddhism the official religion if you so choose (and the factions you previously backed will be disappointed in you if you don't).

Hmm, does this mean the Kirishitan Japan achievement is slightly changed?

It hasn't changed in what it requires but it has changed in how you do it.
For people with the DLC the most straightforward way to do it is to have the incident and go all christian and then form Japan to switch :)
