EU4 - Development Diary - 11th of August 2020

Good morning! In today’s dev diary we’ll be taking a look at three nations in Maritime South-East Asia: the Sultanates of Brunei, Malacca, and Aceh. Each of these nations founded successful empires during our period, and each has a unique set of national ideas and missions.

malacca_missions.png


Mission trees for Malay nations other than Majapahit are split into 4 sections. In red are missions unique to that country, in this case Malacca. In green and blue are missions available to all Malay nations, and in purple are missions available only after forming Malaya.
The Malacca Sultanate is a descendent of the Srivijaya Kingdom which dominated Java, Sumatra, and the Malay Peninsula prior to the rise of Majapahit. Malacca won the favor of Ming China during the period of Zheng He’s voyages, which set the rising city-state up to be a serious contender to Majapahit’s hegemony. By 1444 Malacca is the richest city-state in the Malay world due to its maritime control over the straits. Malacca would go on expand further on the Malay Peninsula and even onto Sumatra, before ultimately succumbing to Portuguese invasion in 1511.

Malaccan missions reflect their expansion path and diplomatic ties. Some highlights:
  • Wherever appropriate, Subjugation CB’s are awarded instead of permanent claims
  • If you complete the Subjugate Pahang mission by vassalizing Pahang, they will get a ruler of your dynasty, reduced liberty desire, and their religion will be changed from Mahayana to your religion.
  • Malacca is no longer a Ming tributary in 1444. Though in theory they maintained their relations, in reality Ming had largely abandoned its interests in the region. The Emissary to the Emperor mission allows you to restore your special relationship with Ming China.
  • Befriend Champa ties in with one of Champa’s missions - Champa needs to make a Sunni friend in Maritime SEA which gives them the option to convert to Sunni. Completing this mission grants a Subjugation CB against Champa’s greatest enemy: Dai Viet.
  • The mission Make a Show of Force requires having a superior army to both Majaphit and Siak. By demonstrating your superiority over their old overlords, Siak will willingly become your vassal.
  • The Develop Malacca mission can upgrade Malacca’s Center of Trade to level 3 after you improve its development and construct buildings in the province - including a Fort to repel the pesky Portuguese.
  • Loyal subjects grants -10 Liberty Desire in all your subjects until the end of the game.
  • Destroy Majapahit, as you might imagine, requires Majapahit to entirely cease to exist as well as for Malacca to gain a foothold on Java. Completing this mission awards a version of Majapahit’s unlimited subjugation CB: the Malacca Campaigns CB can be used against any country in the Malay culture group and the warscore cost for vassalization is reduced by 25%.

Malaccan national ideas allow them to truly dominate the spice trade and get the most out of their vassals.

The Aceh Sultanate wouldn’t reach its apex until the reign of Iskandar Muda in 1583, but it’s available to play from 1444. Aceh’s missions and national ideas are also available to neighboring Pasai, which was richer and more dominant in our start date. Iskandar Muda’s conquests would gain Aceh an empire spanning most of the Sumatran coast as well as parts of the Malay Peninsula. Perhaps the most important contribution of the Aceh region to history is its status as the Porch of Mecca, the most prominent hub of Islam in Maritime SEA.

Aceh’s mission tree follows their historical conquests of Sumatra and the Malay Peninsula, but more interestingly it also encourages the player to spread Islam across the region. Some highlights:
  • Completing the Porch of Mecca mission allows you to use the Propagate religion trade policy with only 35% trade power in a node (down from 50%), and also unlocks the Sword of Islam CB, which allows the Force Religion peace treaty against nations with Sumatran primary culture. This CB evolves as you continue to spread your faith across the islands, gaining the ability to target Javanese, Sundanese, Moluccan, and Sulawesi cultures. Completing this branch of the mission tree allows you to use the Sword of Islam CB against any neighboring heathen country.
  • Hindus and Buddhists in the Malay culture group now have a decision to convert to Sunni Islam if it becomes their dominant religion. This gives Aceh the option to spread their faith through peaceful trade or by military force; the choice is yours.

Acehnese national ideas reflect the focus on trade, navy-driven conquest, and religious conversion:
Code:
ATJ_ideas = {
    start = {
        global_ship_cost = -0.1
        global_missionary_strength = 0.02

Brunei is a renegade Sultanate, breaking away from Majapahit rule while also avoiding an uncomfortably close relationship with Ming China. The Bruneian Empire would grow to encompass the entire coast of Borneo as well as parts of the Philippines, and was able to resist repeated attempts at European domination long after many of its peers had fallen.

Brunei’s missions lead them to unite Borneo under their rule, and also on a campaign of conquest in the Philippines. The missions Impress Manilla and Impress Sulu vassalize those nations if you can maintain good relations with them, regardless of whether they’d normally accept vassalization. Many of Brunei’s missions also add a province modifier to uncolonized provinces that make them much faster to colonize, hastening their unification of the islands.

Brunei’s national ideas emphasize their dominant navy and diplomatic prowess:
Code:
BEI_ideas = {
    start = {
        land_morale = 0.1
        global_ship_cost = -0.1

dd_orang_laut.png


One last thing for today - last week I showed off some new Estate Privileges, but there is one I didn’t show that is exclusive to countries with their capital in the Malaya region. The Orang Laut were (and still are) groups of maritime nomads who extensively engaged in trade with the Malay kingdoms. They were often employed to divert trade to certain ports and to deter pirates, and would grant their allies lands and titles on the islands within their domain. This is in fact how the Malacca Sultanate got its start - Seri Teri Buana, a Srivijayan prince, was granted the small Kingdom of Singapura (modern Singapore) by the Orang Laut, a polity which would eventually become the Malacca Sultanate. Malacca begins with the Orang Laut Alliances estate privilege.

And that’s all for this week! Next week’s dev diary will be a focus on Vietnam, including the new mission trees for Dai Viet and Champa.

1. And how exactly would you reach them? A naval invasion with your 10 cogs? There's also The point of historical accuracy. WHY does this truce even exist? There is zero historical reason for this to exist, it's merely a bandaid covering the real issue of bad AI not handling hordes properly.
Exactly, but it isn't too unlikely that you can reach them by land because someone involved will probably get military access from Jianzhou.

There actually is a historical reason for the truce to exist. Joseon attacked the Jurchen in 1433 and conquered northern Hamgil.
3. Korchin and Mongolia are in the Tartary region IIRC. However you are correct about Yeren and Nivkh having 3 dev provinces, I forgot that Manchuria got moved to East Asia last patch. Still makes no sense why Korea has 3 dev provinces however, Northern Korea is nowhere near as sparsely developed as Siberia.
Yeah they are. The but the dev is probably low because they wanted to implement as war ridden land.

4. You're still stuck with them until they get into a war that you can enforce on, which means they need to be the war leading offender, which is rare considering their tiny size. Might as well wait until Japan unifies before you get the chance to do so.
This isn't too much of an issue imo. I play a lot in Japan so I know who to definitely not improve relations with. I agree that it is to some extend a waiting game, sometimes more, sometimes less. But what else are you gonna do anyway :b

AI Japan takes centuries to form, not really keen on waiting that long. It's also an easy way to get the foot in the door.

The Jurchens in Korea were not the same as the Jianzhou Jurchens. Jianzhou is the name the Chinese gave to the three Jurchens tribes then living in Manchuria (Jianzhou, Haixi and Yeren). The Jurchens in the northern parts of Hamgyeong were unorganised tribes of no real identity, and even then they were limited to what is the province of Yukjin; Gyeongseong has no reason to be Jurchen cultured.

Even if we do exclude Yukjin, the rest of Korea has pitiful dev, with Jeju and Gyeongseong having 3 dev, and the capital of Hanseong having a laughable 10 dev. Even some of the Central Asian steppe provinces and interior African provinces have higher dev than this. Korea in total only has 130 dev, which is one of the lowest dev to population ratios in the game, barely ahead of Ming.

And that's exactly the problem with So. Being sat there for a century having your coast raided is NOT entertaining at the very least. Even more so when there's nothing you can do about it. Japan's high dev and province count means that their navy is always bound to be stronger than yours until you conquer the Chinese coastline, which means that your coastal provinces will get raided until they get annexed (By either you or Ashikaga)

Li Manzhu was the commander of the Jianzhou Guard and was defeated by Choe Yun-deok in 1433. So Jianzhou and Joseon were definitely at war.

Also Jianzhou isn't the name the Ming gave to a tribe, but to a group of tribes. One of those tribes were the Huligai to which Li Manzhu and the former commander of the guard Ahacu belonged to.

I think that both provinces should have korean culture since they were essentially build up by korean settlers after they took the chance when Möngke Temür was assassinated.

Will content like missions available to more or less every country in a culture group be something that you plan to extend to other culture groups?

1. You start off with a 5 year truce with Jianzhou, the only expansion path you have.

2. Declaring wars now makes you take a stability hit. Oh but you also get -4% dev cost, fun times.

3. Manchuria got their development nearly doubled, Korea still has absolute garbage land. The only 3 dev provinces in East Asia are now in Korea and Hokkaido.

4. So. FUCKING So. Wave goodbye to prosperity.

5. All the Jurchen tribes now have the great military ideas, you're still stuck with 10% infantry combat ability. At least they don't have -10% tech cost while you have 5%.

6. Several new bad events that hit you with stability hits, estate loyalty drops, estate loyalty equilibrium drops, and rebels.

7. All of East Asia (yes, including even Ming) now get perma-claims on the entirety of Korea. Now the reverse is also true in that Korea gets perma-claims in East Asia, which I honestly find slightly immersion breaking, considering how Korea didn't really have much ambition beyond Manchuria and Japan (which was mostly to counter pirates)

Remaining issues:

1. Yi Hyang is still a 2/1/1.

2. Instead of giving Korea proper naval ideas Paradox gave them the same one Japan has (7 years into the game that is). Korea got its naval legacy from defeating Japan. Go figure.

3. Confucianism is still the worst religion in the area, if not the worst non-Pagan religion in the world.

The middle east and africa in its whole are portrayed like unpopulated backwaters, it's not so bad in east asia :p
But I get what you mean, Korea has very low development

Considering how it was once Sulu who sacked Poni (Majapahit affiliated Brunei before Brunei rebelled and Islamised), in a rebellion against Majapahit, and it is also Sulu who who intervened in the Bruneian Civil War and was awarded Sabah shouldn't there be a mission tree for Sulu too? Also other precolonial states I would like featured is Maynila and Dapitan at Bohol.

I support that Sulu should be a part of the scope of this update as they were active in Borneo throughout EU4's timeline

A idea for new tributary interaction and casus belli:
New interaction for overlord: Demand hostage prince: Make target subject heir become hostage prince
- Only heir under 15 year old
- Only for loyal tributaries
- Greatly increase liberty desire
- Hightly chance heir change to culture/religion of overlord
- Have chance heir raise stats
- If ruler of target tributary die, target can choose accept hostage prince to become new ruler or not
* Accept: small improve relation, trust, liberty desire with overlord, penalty on unrest, prestige and legitimacy, small bonus mandate/legitimacy for overlord
* Refuse: choose other ruler, greatly penalty relation, trust, liberty desire with overlord, have chance overlord "Military intervene" (detail below)
- If target subjects join a war against overlord in time heir hostaged, heir die.
Whenever a ruler dies and subjects refuse hostage prince, a rebel change ruler/dynasty in tributary nation, overlord can choose a decision:
1. Accept new ruler: large improve relation, trust with that tributary, lightly penalty relation with all other
2. Censure new ruler, but their internal affair: lightly penalty relation that tributary, small bonus on mandate/legitimacy and relation with other tributaries
3. Military intervene (Only if tributary have bad relation with overlord, so if tributary keep relation wwith overlord good enough even have prince hostage overlord can't intervene):
- Immediately small penalty mandate/legitimacy and relation with all tributaries
- Start war with some accepted peace offer:
* Force return throne (restore old dynasty, prince hostage become new ruler, improve relation on all tributaries, regular bonus on mandate/legitimacy, greatly improve relation, trust, liberty desire with target tributary).
* Force vassal (restore old dynasty, prince hostage become new ruler, make target become vassal, regular penalty relation on all tributaries and mandate/legitimacy, greatly penalty relation, trust, liberty desire with target tributary)
* Accept new ruler with a price(small war cost, accept new ruler, target remain tributary, pay large amount gold, regular penalty relation on all tributaries and mandate/legitimacy)
* Can't cede province
- If overlord lost/white peace: liberty target subject, greatly penalty mandate/legitimacy, increase liberty desire on all tributary.
I want a way to decrease autonomy of tributaries, but it'll not easy and risky for mandate/unrest of overlord. Only one war lost, with severe impact on mandate and other subjects relation can knock out an empire (such as Sui dynasty after Joseon invasion). Besides, it's also a peacefully method to spread overlord's culture influence to others by educate the subjects heir.
This is my first post and my English is bad, please forgive me if i have some mistakes.

Still waiting for sth about central-eastern europ. Every coutry bordering PLC has uniqe missions/ special units and goverment events. There was a patch called Poland and all it did was spliting provinces. Lithuania is basicly ticking bomb since it always spawns big stacks of every kind of rebels. Basicly the region of PLC and Scandynawia is totaly underdeveloped by all means

IMO I think the broader islamic world needs a major revamp and rework, litteraly only the ottomans are by far a "threat" if you play as a western european nation; but even then they act as a paper tiger
The development in this super region is also severely underdeveloped, I mean reknown cities of the indian ocean trade are at max 10 development... Mogadishu, aden, masqat, thatta, jeddah, basra, hormuz etc.
Persia in its whole is shown as a desert devoid of life and flora :p
North africa gets overrun by portugal on its own and naples beats up tunis most of the time; I agree that poland also needs a dire rework, but the islamic world is much more of immediate need of it
You can steamroll the MENA region without any dangerous coalition or resistance with ease

AI typically doesn't pursue missions aggressively, in my playtesting I haven't seen this as an issue at all. When you would get a subjugation CB from a mission but the target is already a non-tributary subject or doesn't exist, you instead get permanent claims on the relevant provinces.
I guess you *could* try to do some kinda new, malayan-mission specific transfer subject CB that you get on the overlord if it's checked that the subjugation target isn't independent when you claim the mission (but I don't know how adversely that would affect balance in terms of abuse)

buff Korea pls and rework tributaries
No but seriously the real reason I'm posting this is because wtf is MLC_ideas. The balance between the national idea groups shown is so bad and idk if it's intentional or not.
Malacca: I don't think it takes a genius to figure out that ZERO quality combat modifiers is extremely bad. Malacca doesn't even have trade efficiency or goods produced so it fails at being a trade empire. They don't even have any direct income boosting ideas, actually. I seriously fail to see how this made it past the development board.
+1 Tolerance Own, +1 Legitimacy, +1 Diplo Rep are all filler ideas. Malacca also has so many low-quality trade ideas as well, like 10% Global Trade Power and 20% Trade Steering. Get rid of the filler ideas and put in trade efficiency and/or goods produced and also add in at least one combat modifier (pref. Naval Morale or Engagement Width).
Aceh: The 15% Naval Morale alone already makes this set superior to Malacca's entire group. 10% Tech, -1 Interest, Production, Colonial Growth, etc. all of these push it way over. This I feel is the most balanced NI set. It's a good unfocused nation and is similar to Tuscan ideas in that it shows the right way to make a "jack of all trades" national ideas set. It's not major power material, but that's fine since all these nations can form Malaya anyways (which I hope has good NIs).
Brunei: The standalone 10% Land Morale has no reason to be there. 15% Morale, 20% Galley CA, and 10% Dura means Brunei is the premier naval superpower in SEA and will probably be the most picked nation to form Malaya (in multiplayer). This is actually the best inland sea naval NIs we've had so far (Venice has no morale).

Conclusion: buff Malaccan ideas jesus christ

Now seems like a great time to add the strait of Johor to the map. The map of Johor looks completely wrong, presumably because it was imported from a zoomed out satellite map with rivers and waterways added later. Singapore is an island, and the strait of Johor is an extremely important geographical feature that shows up on every map of the region. Even old Portuguese maps that think Singapore is southeast of malaya don't have it as part of the mainland.

In related news, it's great to hear you're adding more gameplay depth to southeast asia.
 
If you guys are going to keep adding estate privileges like this, you reaaaallly need to expand it to have more than 5 slots each. They're already packed as it is.
Hard limits rarely make any sense... It seems to me that everytime they release a patch with some new hard limit, they then have to spend the next few years turning it into a soft limit (a few years because first all the management has to be convinced that a soft limit would be better and to show at least a thousand posts of people complaining). Wouldn't it be more practical to ALWYS have soft limits? Or was it a medieval custom for estates to have only 5 privileges max? Or 999 mana points? Or 200 Papal influence, or 100 Imperial authority, or..... well... need I say more?
