HOI4 Dev Diary - Yugoslavia and Romania

Hello and welcome to another developer diary for the 1.10 Collie patch!

Today we’re going to be focusing on some content coming with the patch that will add new content for owners of the Death or Dishonor expansion. Everything that follows will be accessible to DoD owners and will not be unlocked by purchasing Battle for the Bosporus. Some of you may already know this from the leaked screenshot on the Steam store, but Yugoslavia will be getting a light rework coming free with the patch for any owners of Death or Dishonor.

When I originally joined full-time on the project, I was given a list of common complaints from the community regarding the content in Death or Dishonor. Most of these issues were trivial, but none had a longer list of complaints than Yugoslavia so it seemed right that instead of attempting to stitch together a series of minimal low-visibility fixes, it would be best to do a partial rework of the Yugoslavia tree.

This is not quite to the scale of previous major reworks, however. The first draft of changes began as something I worked on out of my free time, so I wanted to keep scope low and avoid creating too much extra work on top of the existing BftB content while improving the overall quality of the Yugoslavia tree to give players more options to explore both history and alt-history.

Let’s begin with the communist focuses, which have seen a little change. For a long time, Yugoslavia was able to branch off and make its own faction with itself, Bulgaria, and Albania but the chances of getting those nations to become Communist in a regular playthrough was pretty dang low. So, Yugoslavia now gains access to a series of decisions to steadily support a peasant’s uprising in both Bulgaria and Albania, creating a viable way to bring them into the Pan-Slavic Worker’s Congress.

Once done, Yugoslavia will gain access to a whole slew of new focuses with their faction reorganizing into the Pan-Balkan Worker’s Congress. Romania, Turkey, Greece, and Hungary are all valid targets for peasant uprisings, so if you ever wanted to see the Balkans start wearing purple, Tito now has all the tools to do it.

Next, we’ll take a look at the old monarchist focuses and how overall the decisions you made were pretty objectively one good decision and one bad. What I really liked about Yugoslavia was the fact that you were constantly making decisions with every focus you pick, following this kind of ladder-design, but with the new tree, I wanted to take that a step further and create some more meaningful and involved choices.
pasted image 0 (5).png


At the very start of their focus tree, Yugoslavia has a choice to either pursue Evolution or Limited Self-Government. Evolution is basically the old Yugoslavia design, where you attempt to stomp out nationalism in your country by whatever means you see fit.
pasted image 0 (6).png


First, establishing the Banate of Croatia no longer makes Croatia a puppet and instead gives Yugoslavia a temporary softer version of Croatian Opposition, but choosing to Crush the Ustase is now a much more involved process and can result in Croatian Nationalism being removed entirely. Crushing the Ustase is a series of decisions tied to two missions. One mission will make the Ustase rise up in an independence war, and the other will peacefully stamp them out. Players have access to a number of decisions to either delay the uprising or speed up the peaceful removal of the Ustase and it’ll take a lot of close attention to keep Yugoslavia in one piece while stamping out nationalism.

For the next two focuses, Yugoslavia has the option to both play appeasement to Italy and Bulgaria while also permanently removing some of their problems. The old focuses do what they always have, but now the negative spirit gained only lasts for a few years, but giving up the territories to these powers will now grant a significant increase in opinion while removing the spirits completely.
pasted image 0 (8).png


Now is as good a time as any to bring up the reworked Yugoslavian states! The goal of this state rework was to facilitate for both modern Balkan borders for the sake of releasables and historical occupation zones.

But instead of doing all that work to maintain the union, Yugoslavia can choose instead to grant self-government to its constituent parts, permanently removing the negative spirits at the cost of losing all of its territory besides Serbia proper. Throughout this path, Yugoslavia will get to choose exactly how it wants to devolve itself; should the two Banovinas of Croatia be individually independent or should they be merged into one? Should the contested territory of Vojvodina be fortified against the Hungarians, given up to them as an act of appeasement, or granted self-government? The ladder design here is more of a choice of how chaotic you want the Balkans to be than a strategic decision. Personally, I enjoy achieving peak-Balkans and granting autonomy to everyone.
pasted image 0 (9).png


Once done tearing itself apart, Yugoslavia can attempt to reintegrate its constituent parts, or grant full independence to the Balkans, replacing Yugoslavia with a military alliance backed up by a hefty number of free units shared between each of the Balkan nations. Going down the route of independence, the Balkans will have more than double the number of troops Yugoslavia begins the game with, so breaking yourself apart may not be such a bad decision with the Axis breathing down your neck.
pasted image 0 (10).png


Prince Paul is no longer the blank slate he was in the old Yugoslavia design and trying to keep him in power means attempting to align yourself with the Axis. Just like before though, both Britain and the Yugoslavian military are deeply opposed to an Axis alliance, and attempting to do so may lead to a coup.
pasted image 0 (11).png


However, should the coup fail and Paul remains in power, the regency will hardly be a regency after they rejected the right of the legitimate heir to take the throne, so perhaps a new King will be needed to guide Yugoslavia in its dark future…
pasted image 0 (12).png


Joining the Allies brings its own set of difficulties, besides the distance of your friends in the West. King Peter is a mere 12 years old in 1936 and if you attempt to end the regency too early, you will be saddled with a monarch woefully unprepared for rulership.

Given a few years however, King Peter matures into the legitimate heir of the Yugoslav throne and may marry himself into a little more than just the Allies.
pasted image 0 (14).png


The Royal Wedding focus allows King Peter to marry himself to many of the major Princesses in Europe and who is available adapts dynamically based on the current state of the world. If the Kaiser returns, Yugoslavia will be able to marry a German princess, similarly they may marry a Spanish princess should the Carlists win the Spanish Civil War. Their choice will then inform the outcome of the focus “The Royal Alliance”, which can bring Yugoslavia into a faction with whomever they chose to marry, with Princess Alexandra of Greece resulting in a historic Yugoslav entry to the Allies.
pasted image 0 (15).png


Yugoslavia is not the only Death or Dishonor country getting new content, however. Romania will now have the ability to change sides midway through the war via a decision following a government coup.
pasted image 0 (16).png


On top of that, the Divide Yugoslavia focus is now a game of bidding and demanding from the powers Romania chooses to invite to the dogpile. Similar to the SCW garrison system, each nation can make up to three bids on a Yugoslav state before being locked in as the controller. When each state is claimed, Romania may push the button and issue their demands to Yugoslavia. This can lead to some… interesting looking Balkans.

There are more changes coming to Romania, but for that I will hand you over to our Producer.

Hi everyone, Vash here with some of the changes I’ve made for Romania. Back in February, one of our forum members, Zeprion, made some suggestions for Romania that we unfortunately couldn’t get to in time for La Resistance. While I still didn’t have the chance to get through the full list, I was able to make a few changes that I’m happy to talk about!

Previously, you may have noticed that the political parties and leaders in 1936 were swapped. Historically, the ruling party in 1936 was Democratic PNL, with Gheorghe Tătărescu as the leader. Armand Calimanescu was also the leader of Non-Aligned FRN. This has now been fixed, and they both have the correct party affiliations. This also means that Romania now starts off in 1936 as Democratic instead of Non-Aligned. We’ve also done some balancing on the back end to account for this change.

Next up, we also switched the starting fascist leader to Octavian Goga, who was the leader of the National Christian Party (Partidul Național Creștin). That means we’ve also switched the starting fascism party to the PNC.

pasted image 0 (20).png


What this means for the player is that upon taking the Iron Guard focus, Ion Antonescu will become the figure head for the fascist party and the party will be renamed from the PNC to Garda de Fier.

Another important historical fact that Zeprion brought up was that King Michael’s Coup was not against his father, but against the fascist Iron Guard. We’ve now relocated this focus to the bottom of the fascist tree.

pasted image 0 (23).png


This now gives the player three options to choose from. You can either stage the coup and appoint King Michael as the leader of the Democratic Party under a constitutional monarchy, force King Carol’s abdication and replace him with the leader of the most popular party, or Handle the King and allow King Carol to stay in power since he has changed his ways for the better.

We’ve also updated the state priorities for some of our building focuses to ensure they don’t give infrastructure bonuses to states you may have given up prior to the start of the war such as Bukovina, Bessarabia, and Northern Transylvania.

And last but not least, we’ve given Constantin Sanatescu a bit of an upgrade! Previously he was only available as an Army Chief with a defensive bonus, but he is now available as a General as well.

That’s it for all the Romania changes for now. Thanks again to Zeprion for all the feedback, and I hope everyone enjoyed this week’s Dev Diary!

Brilliant! Thank you for your hard work, good to see Macek represented, considering his major role in Yugoslav politics.
And good to know that I won't have to rush the industrial path before the devolution.
Thank you, it isn't said enough but comments like this really brighten our day!
Down the road will we see any tweaks with Hungary or Czechoslovakia?
There are no major changes to Czechoslovakia or Hungary in this patch.
I am loving the rework but can we please just get close to historical borders in Yugoslavia. And micro states are fine. We have Hatay, Southern Serbia now, as well as memel. Really i would over to see Ljubijana, and the art of Macedon ceded Italian Albania. I would just love to see this addition. This is a ww2 game and imo ww2 borders should take precedent over modern borders.
Balkan borders are the bane of every content designer's existence. There is a desire to represent everything; internal Yugoslavian administrative divisions, historical occupation zones, and logical borders for releasable tags. Unfortunately, it is almost impossible to satisfy all of those desires, and attempting to do so would necessitate the creation of a dense myriad of different states that exist for different purposes. The rework here allows you to get an approximation of historical occupation zones and balkanize the Balkans in a logical way, even if it's not 100% reflective of internal Yugoslav administration wherein state borders were largely based on rivelines rather than cultural regions.

I had a question about the”Slovenia for Support” focus. The focus image suggests that Slovenia would be given to Germany, but the map images suggest Italy. Does it depend on the focuses that Germany (Anschluss) and Italy (Claims on Yugoslavia) have taken, or do you or the other powers in question get a choice?

Exactly. If Germany has completed Anschluss by the time Yugoslavia concedes Slovenia, it will be given to the Germans.

Glad to see the Romanian changes aswell. Did not expect that, but it was needed and is welcomed! Especially changing sides during the war, something that was most needed to better represent Romania late war.

This might be too much to ask, but will Hungary be able to do the same? They tried to change sides aswell. Did not go so well because of the German invasion and parallell fighting with you guessed right; Romania.
I mean I like this, but I would hope the focus King Michales coup would declare war on germany and give the soviets military access like IRL

While the addition of Romania being able to switch sides is great (hopefully it can also switch from Axis to Comintern) I am concerned about King Michael's Coup being mutually exclusive with Force Abdication. Historically King Carol II abdicated, and it was years after that Michael decided to coup d'etat Antonescu. I would argue for the focuses not to be mutually exclusive.

If switching sides from Axis to Comintern is not possible, then I would argue to additionally make the King Michael's Coup focus to make Romania join Comintern, but at a price of making Romania USSR's puppet after the war.

When Romania swap sides for the Allies I doubt they will remain at war with the Allies.
 
Is DoD worth picking up now? It's the only dlc I don't own as i wasn't really sold on it before.
I've always liked DoD. I think pre BftB the Yugoslav tree was a bit lacking etc. But honestly, Czechoslovak tree is the real gem there. Czechia usually is ignored as it is annexed on historical focuses, but honestly, the Czech tree has a bunch of stuff for industry, military and politics. Not to mention they start off with a relatively large industrial base.
Also, in case you manage to do ir as Czechia, you can reform austria hungary and get a lot more cores.

Now that's too bad, hopefully we can see a few additions some time soon. Their focus trees are the best out of the bunch, but ever since the addition of decisions in WtT, the countries as a whole feel a bit lackluster without them, especially given the scope that recent DLC have (most recent example is BftB; Turkey alone has countless decisions). Who knows, maybe in the future they can get a few touch ups as well (making "Miklós Horthy and the Habsburg Prince" less RNG heavy would already do wonders for me)!

Does the Pan-Slavic Worker's Congress etc. focuses create puppets/collaboration governments of the now-purple nations, or is it an independent faction member situation?

Relatedly, any thought to giving access to the Balkan Federation as a country unification decision to non-Bulgarians the way Austria-Hungary formation's available to Czechoslovakia and Austria where Hungary does it via focus?

And I am pointing out that as of now you can form Greater Hungary peacefully, but then Yugoslavia only give up Vovjodina, because that is the ultimatum. West Banat may be annexed (and it is a Magyar core after renouncing Trianon) through war. If you are not in a faction it often leads to war. As long as Yugoslavia do not enter the Axis or Allies it is fairly simple to get West Banat.

What the devs are supposed to do and what they intend is obviously out of my purview.
Man, i forgot that West Banat is historically under German-occupied Serbia. So, that's cleared up, and i'm cool with that. Sorry for bothering you over this pointless argument, and i have explained it on the Reddit thread.

About Zaolzie, perhaps when Czechoslovakia complies to the Hungarian demand before Germany demands Sudetenland, Poland can move in and intergrate Zaolzie. Another quick fix, @Meka66?

Perfect, since I still have the Romanian and Yugoslavian achievements to do but have done the Czech and Hungarian ones ;)
But that makes me wonder... is a Czech and Hungarian update dev diary coming as well next week? Maybe?
