EU4 - Development Diary - 14th of March 2017

[DDRJake]

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:

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!

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.

 

[Trin Tragula]

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, howdoes 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?

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).

 

[Trin Tragula]

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

 

[Trin Tragula]

EDIT: A question I'd have, what with all the wonderful new ideas for the Daimyo, will they get the choice to keep them or change to the standard Japanese ideas upon forming Japan?

Yes.

 

[Trin Tragula]

The main concern are their unique +10% Discipline and +15% Inf CA boosts. Please don't tell me you've changed that combo!

Discipline is 5% now (but that was already decided before we redid the set) but infantry combat ability remains at 15.
There are other bonuses that are out of the normal range though.

 

[Trin Tragula]

Do the Oda clan get some special national Ideas too ?. Sadly they only show up later in the game iwould love to unite Japan with them. Maybe they can be formed in the national dicision thing as the clan who ownt he province there so we could still get nobunaga

Not at this time. We chose to focus on the tags available at start for now but we would love to add more in the future
Hopefully which Daimyo you'll pick will be a real choice now and not just "how much development do I want to start with?".

 

[Trin Tragula]

With all due respect this did not answer the question, what about countries that are Shinto but neither the Shogun or Daimyos? I assume they get the Isolation Mechanic on their own little bubble with no interaction to the Shogun and it's Prestige correct?

It answered the first question, I missed this part

Non Daimyo Shinto countries also get incidents but may not be able to get all 8 (most notably you can only get the shogunate Authority incident if you are the subject of a Shogun). It should also be said it is also quite possible to go through an entire game even as a Daimyo without getting all of the incidents.
And of course Shinto countries that aren't daimyo or shogun will not have their isolationism impacted or impacting the shogun.

@Trin Tragula @DDRJake
Just curious as to why there haven't been any new comet events in the last few expansions?
Aside from East Asia, will there be any new nations that will receive unique ideas? I may have played at least 80% of all the countries available at the 1444 start, and many releasable nations, but it honestly doesn't make sense to me why Bulgaria has their own unique ideas, but many Germans states, Indian Sultanates, and many others either still have "national ideas'' or ''insert group name'' ideas.
On a serious note this expansion looks great and I can't wait to play in SE Asia after all the flavor, events, and map rework are done.

The ambition is of course to have as many tags as possible with their own set. To this end we have often prioritzed tags with generic ideas over those with group ideas. This is now shifting as almost all tags in the world have non-generic ideas (but sadly not all yet).

There are sets outside of Japan coming for 1.20 but the main focus has been on breaking up the Daimyo group for some diversity this time around.

 

[Trin Tragula]

Out of curiosity, which tags still have the generic set now?

I'm on my phone now but from memory in 1444:

Tripura, Ethiopian Minors

Garhwal gets a set in 1.20.

 

[DDRJake]

I like the new japanese skins.

I'll be sure to pass this on to our 3D artist. We should have renders available for viewing in due time.

Hm....I wonder....

Say for example, you're playing France and you take over Japan (and the rest of the world while we are at it), and the French Empress (that's you) becomes fascinated by Shintoism and adopts it as the religion of the Global French Empire, how does Isolationism work then? Or how does that affect the entire empire?

Can a non-Japanese empire adopt Shintoism to begin with?

Such an Empress would then have her nation interacting with the Shinto mechanics, Incidents and all, starting at Adaptive levels of isolationism.

I believe the venetian vassals also have generic ideas

Ionian and Naxian Ideas would beg to differ.

Additionally, as usual, values and such are subject to change from announcement in Dev Dairies to release. In the case of Isolationism level effects, they've been tweaked too.

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​

I'll be updating the first post accordingly.
