Hello and welcome to today's development diary for Europa Universalis IV. It's actually a well earned(?) day off for me but I'm doing a once unthinkable thing and working a bit from home. Last week I said we would take a look at a very influential dynasty of the time period. Sorry to disappoint all the Velikopermsky and Dandani fans out there, but I had the Osmanoglus on my mind.

It would be an understatement to say that the Ottomans gave the world a good shaking in this time period. Furthermore, they are one of the more commonly played nations in EUIV. We wanted to give them a little something to bring out their unique flavour since it was always a shame that they are a run-of-the-mill Sultanate. It has also been pointed out on numerous occasions the oddity of a situation where you have the Ottoman nation..without an Osmanoglu at the helm.

So to that end, in the still-unnamed upcoming expansion we have added a unique government type for them: The Ottoman Sultanate.

The Ottoman Sultanate does not generate heirs like normal monarchies do. The ruler of the Ottoman Sultanate will have their own Harem to ensure the dynasty lives on. At the age of 30, your ruler will select one of his sons to be the heir to the throne. They will, of course, be of your dynasty



So an Ottoman Sultanate shall always be blessed by the strong line of Osmanoglus. That is to say unless the Sultan dies without an heir. In that case, they'll still end up with an Osmanoglu. "Blessed" can be a relative term here.



There are a couple dozen events accompanying this unique government type to simulate the power struggle and intrigue of such a succession system and should add a couple of fangs to that already formidable Ottomans.

While this is unique to the Ottomans, any modders out there can easily allow this for other government types with the has_harem = yes line.

I feel like we're on a roll when it comes to governments and rulers so here's another thing for today's Development Diary. Abdication.

Yes, it has long been a requested feature in Europa Universalis. When Enrique or his low-stat kind just refuses to die you can abdicate and let your next in line take over. This requires you to have an of-age heir and to have either ruled for 25 years or be 60+ years old. It will come with a considerable hit to your legitimacy/unity and prestige but I think we've all had times where we wanted our monarch to Die Please Die.




Ottoman Sultanate and Abdication are both paid features in the upcoming expansion which we have magically managed to keep unleaked name-wise.

I've been mentioning a lot of paid features lately but it's good to remind ourselves that with all the paid expansions come free bugfixes and features from the accompanying patch. A small change that will be coming up in 1.18 that I want to share is to do with succession wars. I'm not to happy with how right now, they have two conclusions: Either the new overlord keeps their union or the nation fighting them over it take leadership over the union for themselves. Now, we will add a peace option which simply breaks the union for all parties involved.



Simple, sensible, and added free in 1.18 for those times where you just want to keep the status quo. Warscore cost scales with the junior partner's size.

Happy midsummer everyone, I'm off to....oh, right, I need to tease upcoming Diaries. Hrmm~ Well, we've touched a lot on rulers but would you believe it, we're not quite done with the changes in the throne room. We'll come to that in the future. As for next week, we'll switch it up on the battlefield. See you then!

Hello and welcome to today's development diary for Europa Universalis IV. Let's take a good look at our King/Khan/Doge/Emperor/Prince.

The ruler of your state is of prime importance to your nation but when you see your new heir birthed or khan taking the throne, it's often a quick look at their 3 monarch point stats followed by either a face palm or a fist pump. As a feature in the upcoming expansion we will be giving a touch more identity to these walking point generators with Ruler Personalities.


When a ruler comes of age they will develop a personality important to the function of the state. They will develop another trait after ruling for 10 years and a further personality after ruling for a total of 25 years. These personalities will grant a modifier for your nation as well as bonus options in event and changes to the AI's actions. For Duke Francois do Dreux here, he has become a careful individual who will enjoy lower AE in expansion.

Most personalities are a boon for your nation but not all are so positive. While it would be lovely if all your rulers were Just, Incorruptible and Charismatic, you may well find that your ruler is too greedy for their own good like Vilhelm Skram of Denmark.



King Vilhelm is a tight-fisted greedy guts and will hoover up 10% of your tax income, but there is a silver lining to his greed. Many events have unlockable options now depending on your monarch's personality which will almost always be a superior option. Obscurantism will normally cost a nation in unrest or prestige, but greedy desires drive Vilhelm to seek out a more...lucrative path.

All personalities will unlock such options in some events, as well as have events of their own. Who knows what your Scholarly King or Malevolent Khan will get up to?

Ruler Personalities will be a paid feature in the upcoming expansion, which will be sold alongside the free 1.18 patch.

While on the subject of monarchs, we will be paying special attention to a very influential dynasty of the time period next week, but for now I must take leave. Vilhelm has shaken me down for every ducat I own and I must take care of this.

We've released a small patch today to address some of the more serious issues in 1.17

- Fixed tendency for AI to end up with too much artillery and cavalry late game.
- You can no longer change difficulty after starting an Ironman game.
- Fixed issue where an Ironman game would no longer be valid for Achievements after loading it by pressing Continue.
- Fixed issue where settings were overwritten after loading a "Continue" save game, potentially disabling Achievements.
- MP: Fixed out of sync when upgrading fleets.
As the team continues to work hard on the 1.18 patch and upcoming expansion, we wanted to release this small patch, mainly to tackle the issues with the Continue button breaking ironman saves and an OOS.

Please post any issues found in the bug report forum as usual.

Hello and welcome to today's development diary for Europa Universalis IV. After much plotting and espionage, I have assumed direct control over these diaries, at least for the upcoming months while Johan enjoys some paternity leave.

The feeling of power this gives is immense. EU4 will allow you a similar feeling with a new feature in the upcoming expansion: Great Powers

In 1.18's accompanying expansion, which has yet to be name-dropped, we will grant the 8 most powerful countries in the world a "Great Power" status, granting them bonuses, new diplomatic options and, perhaps most importantly, a glow around your shield to show that you are the superior nation.

Before we address the shiny options and bonuses available to you, let's tackle the question of how to become a Great Power. As we had mentioned in a previous diary, the technology system is getting an overhaul and the Great Power mechanic will make use of this too. Your ranking as a Great Power depends on your Total Development plus half of your Subject Development, then divided by your tech cost. This ensures that early game, large powers such as Ming and Timurids will enjoy Great Power status but as Other powers rise and they lag behind with embracing new institutions, this status will be lost. Of course, If Ming, for example, stays united and forward thinking, they may not lose this status at all. Subject Nations cannot be Great Powers

As a great power you will enjoy a Power Projection bonus. One commonly raised issue is that if you are a huge power without equal your Power Projection is oddly low, since you cannot have any meaningful rivals. The greatest of the Great Powers will enjoy a +25 Power Projection bonus, with the other 7 gaining an increasingly smaller amount with rank 8 getting +10PP. Additionally, great powers will receive a prestige decay reduction. Other modifiers will likely be added before release as we continue to balance the system.



Bonuses are all very well and good, but where's the fun in being great if you can't enforce your will on lesser beings? Four new diplomatic options are opened up uniquely for Great Powers:

Take on Foreign Debt – Pay off all the loans of the target independent non-GP country. Gives +10 relations bonus for every standard size loan of the target you clear, capped at +200, decaying 2/year Also grants +1 trust for every loan cleared, or +2 favours if you have The Cossacks. Requires enough money to pay off target’s loans.

Influence Nation – Pay 1 year of target income to increase relations and grant +1 monarch points in their weakest category for 10 years in a target independent non-GP nation. This raises their opinion of you by 25 for the 10 years, also gives +5 trust. Going to war with them cancels this bonus.

Intervene in War– If there is an ongoing war between great powers but an imbalance in the number of GPs involved, you can make it your business to intervene. For example, if GP Britain is singlehandedly fighting GP France and GP Spain, you as a Great Power Commonwealth can intervene on Great Britain's side to balance out the number of great powers involved.

Break Alliance – This will force a nation to break its alliance with another. They will accept if the target nation is sufficiently afraid of you and you will gain a truce with the nation you force this upon. Useful for stripping your war target of pesky roadblocks.



Finally, you will want to hold on to your status as a great power. If you are pushed out of the top 8 nations, you will be given a 5 year grace period to regain your Great Power Score. During this time you will still have access to Great Power options but if you cannot regain your standing then you will lose them until you rise again or topple those who would claim to be greater than you.

Current 1444 Great Powers:




As usual, the nitty-gritty numbers are very much subject to change as we refine the features.

Great Powers will be available as a paid feature in the upcoming expansion, which will be released alongside the 1.18 patch.

Next week we'll be in the presence of our King/Khan/Chief/Sultan/Emperor/Malik, so I hope you're on your best behavior.

Welcome to another development diary about Europa Universalis IV. This time we talk about something that will be in the next major patch we do.

One of the parts of the game that has not changed much since eu1 is the concept of technology groups and technological development around the world. We’ve added concepts like westernising, and tweaked that one, but in the end Europe has a huge advantage from day 1, and lots of fun gameplay options are limited the further away you are.

So this is what will happen in 1.18, when it is released this autumn..

A nation’s technology group no longer affect technology research.

There is now a concept called Institutions, which will affect your technology research. There are seven different institutions that appear over the game, and if you don’t get them to spread into your country and then get embraced by your government, your technology costs will slowly rise.




Each institution will appear in a province fullfilling certain factors, and then slowly spread around the world. The nation owning that province will gain prestige and monarch power.

Every year the penalty for not having embraced an institution will grow by 1%, so there is a gradual process.

When an institution has spread to at least 10% of your development, you can embrace it in your government, removing the penalty permanently, and also giving a bonus to your nation. The cost to embrace depends on the amount of development in your nation without the institution.

All institutions spread over borders (including 1 seazone away), if relations are positive, and the spread is based on development in the province getting it. There are also lots of other factors related to the spread.

So which are the the seven institutions then?

[INDENT]Feudalism
This is present from the start in almost all the world, except among the hordes, new world and sub-saharan africa. It will slowly spread into neighboring lands, but it is not quick.
Bonus: Gives 1 extra free leader.
Penalty: 50%


Renaissance
This appears in Italy after 1450, in either a capital or a 20+ development province. It will spread quickly through high development in europe, particularly through italy, but can only spread into provinces that have feudalism already.
Bonus: 5% Cheaper Development & 5% Cheaper Buildings
Penalty: 20%


Colonialism
Appears after 1500 in a port province in Europe, who’s owner has the Quest of the New World idea, and have discovered the new world. And will spread very quickly through any port in countries with colonies.
Bonus: +10% Provincial Trade Power
Penalty: 20%


Printing Press
This arrives after 1550, most likely in germany, but can happen in any protestant or reformed province. It will spread quickly in Protestant and Reformed territory, but also into capitals with dip tech 15.
Bonus: 5& Cheaper Stability
Penalty: 20%


Global Trade
This arrives after 1600, in a center of trade in the highest value trade node, and will spread quicker into provinces with trade buildings.
Bonus: +1 Merchant
Penalty: 20%

Manufactories
This arrives after 1650 in a province with 30 development and a manufactory, and will spread quicker into provinces with manufactories.
Bonus: +10% Goods Produced
Penalty: 20%

Enlightenment
Arrives after 1650 in a province that either is a seat of a parliament, or is a province in europe owned by a monarch with at least 5 in all stats. Universities & Parliament Seats spread this institution.
Bonus: 25% Cheaper Culture Conversion
Penalty: 30%
[/indent]


What does this mean?


The progress of Europe is not guaranteed, but most importantly, a nation in Asia or Africa is no longer crippled from day 1, and forced to avoid spending power on ideas and development.

------

We’re constantly tweaking the spread factors, but here are some screenshots from mid 18th century in a hands-off game from this morning.

This is the institutions mapmode, where green are provinces that have all the enabled institutions, and yellow are don’t have them all.



And here is the technology mapmode, of the same game.







Some other aspects that has changed include the following
- New World Native Reforming will give you all institutions that the one you reform from has.
- Trade Companies are available to all technology groups.
- Lots and lots of triggers on western techgroups have been changed to check for specific relevant institutions.
