Hi folks,

It’s been a while since our last update on future plans for HoI, but we’re about ready to show you some of the work we’ve been doing. Before we begin, I’d like to indicate that there’ll be some differences in how we do this. As I’ve previously stated, we want to begin discussion around features and implementation details a little earlier in the process than usual. This means a couple of things.

Firstly, while we’ll be showing off some individual features, we’re not yet ready to give an overview of the entire scope of our next release yet. This will, of course, be coming in the near (ish) future.

Secondly, you’ll be getting an early look at what we’ve been working on, and this comes with all the caveats you might expect: lots of WIP design, interface, and gameplay.

Lastly, for the time being we’ll be producing these ‘design corner’ style diaries every two weeks, rather than weekly. This is likely to change as we get closer to being complete.

Before I hand over, I’ll give you a quick run down of the directive for the feature we’re looking at today: Peace Conferences. Our primary objectives are to:

• Create a system that appropriately rewards participation.
  
• Allow for conflict and conflict resolution within the scope of the conference.
  
• Create a limited ‘economy’ within conferences, where you may have to sacrifice your overall aims in order to secure immediate concerns.
  
• Produce more ‘realistic’ outcomes where the AI is concerned

And with that, I’ll hand over to @Yaboi_bobby to dive into the deeper details!


Hey everyone, over the past months we have been working to overhaul the peace conference system. It is no secret that in HoI4 the peace conference system has a number of issues with how it functions. Combining that with the fact that it is a surprisingly hard interface to learn how to use, it is rightly one of our most disliked and complained about features. We have taken a large step away from how the system currently works and I am excited to show what the future holds for peace conferences.

The first major departure we made from the old system was shifting from absolute claiming of territory to contestable claiming of territory. In the old PC system once somebody claimed a state, that was it. That claim would be locked in and no one would be able to interact with it further. Now, players may contest other players' interactions in the conference. This doesn't come without cost. Contesting claimed territory will come with a point tax, and every time a contest happens the price of interacting with that state climbs further. This effectively creates a bidding war between all parties invested in a given state. This change should have some interesting outcomes, allow mid and low level participants to have more agency, and give players the tools needed to go after the states that are most important to them for things like achievements and forming new tags.

Contestable bids help solve some problems, but without further changes many still persist. One of the most obvious issues was how the old system handled turn order. The old system would order countries by participation, and then go in order based upon the number of points held by participants. Where it gets weird is the fact that the order of the list would get updated after each nation’s turn. This meant that often the top two participants could have enough points when a turn ended that they would simply exchange turns between them and end up completely controlling the conference. This was in some ways a good method to allow two big faction leaders to have majority control after the end of a historical WW2, but is bad in virtually every other case.

We did a lot of thinking about turn order and how to structure the turn in general. Slowly we came to the conclusion that any system with a visible turn order, no matter how it was structured, would put people at disadvantage or advantage depending on turn order. This led to the creation of what we have been calling the “Blind Bid” system.

The main concept of the “Blind Bid” system is that everyone acts simultaneously. The way this functions is that, each turn, every conference participant uses their points to make bids. When every player has finished making their bids, all of the bids are evaluated at once. Bids have a fixed cost much like the current claims do, but now with more modifiers. In any instance where two participants made a bid on the same state, that state is marked as contested and the players involved have the majority of their points spent on the bid refunded. Each time a state is contested, it increases in cost for all subsequent rounds. This effect stacks on a state each turn in which a contested bid happens. The other side of this is uncontested bids. Each turn a bid goes uncontested, it increases in cost for everyone else except for the person who made the bid. This acts to, over the course of several turns, lock in bids as they become too expensive to realistically contest.

At this point you may be thinking “Yeah OK, but I get points each turn, how does the conference end?” This leads us to the final major change: limited points. This is pretty self explanatory. Each participant will get a fixed amount of points over the course of the conference based upon war participation score. The way we do this is by distributing a percentage of those points every turn until all points are distributed. Most of the work here comes down to rebalancing war participation and finding what we consider a good point ceiling for a conference. Limited points will mean, in some cases, that loser nations survive more intact than they did previously, but this should not be a common case. In general, we think this creates a fun and somewhat tense conference experience.

Beyond the big three changes listed so far we have a number of smaller tweaks, adjustments, and rebalance to overall cost of interactions and participation. However, that topic is not worth going into at this point as it is still very much WiP. So with that I will conclude the first overview of the peace conference rework. We look forward to your feedback, hot takes, and hopefully excitement. Until next time o7

As you’ll be aware, it has been a while since our last dev diary, and I’m super thrilled to finally release what we’ve been working on since No Step Back.

We take great pride in our attention to gameplay telemetry that we receive from keen HOI4 players from across the globe, and our data wizards regularly furnish us with relevant information with which to steer development of features. After NSB, we were informed of a clear and scientific trend in the data:



That’s right folks, it turns out that 99.5%* of you exclusively play monarchies. It was quite clear to us that we had a mandate to finally concede to public demand, and add the long-awaited Habsburg branch to the Generic focus tree!

*These results were verified by independent election officials.
Now, regardless of which nation you hold dear, you too can find and install a local member of the Habsburg dynasty, taking part in the restoration of everyone’s favourite neighbourhood hegemony.



After discovering a stray member of the Habsburg dynasty, steer your nation to glory by choosing an appropriate spouse or accidentally inheriting some countries you weren’t aware existed.

No Habsburg tree would be complete without an edifying array of royal marriage candidates, so we’ve included plenty of historically accurate examples:



Once you have secured the bloodline, you can, naturally, expand your sights to join your relatives in other countries in vying for the ultimate prize:



As you might expect, every nation can now join and restore the Holy Roman Empire regardless of where they start.

In addition to the usual focus tree content, we’ll be expanding our ambitions somewhat! We’ll be including three new realistic continuous focuses to the Habsburg branch:




Ultimately we feel that this adds a great deal to the generic focus tree experience, importantly providing a thoughtful, plausible and historically inspired approach that you can enjoy with nations as far afield as you like.

A.E.I.O.U, folks!

Hello there, the time has come to do a fun dive into what you've been playing the game as a community. So over this diary we are going to look into some of the trends and statistics we seen from our telemetry and see how we use it to gain insights in current player trends when working on HOI4. The wonderful data team have been working to get us all the information we wanted and I hope you enjoy seeing some of their great work. As a forward point, as with any data collection we do not store any personal information or anything that can used to identify players in accordance with GDPR.

So first of we will start with something fun, can you guess what this graph is telling us.


If you guessed this was us spotting the continuous naval production focus exploit being discovered you get a gold star, although it seems some of you are still very much into using the focus.


With telemetry we can work to understand our players by seeing how you play and this lets us form an experience players will enjoy. we see this in many ways, for example we can see by player difficulty settings players really shy away from the harder difficulties.



We can also see how players are reacting to new content, here we can see the soviet union and Poland grow and maintain solid new highs in terms of sessions played. Germany still remains you favourite major to play, and for those of you that like playing minors the PRC seems to be the country to go for.



Now lets get into some more specific game related data, player play behaviours are something that always interesting to know. You might think you know what most players are doing from discussions on various discussion platforms, streams and videos, however what's even better is knowing for sure what the meta and average player does.

For example many people really need to check their infantry equipment stockpile late game


Seriously players really enjoy making infantry equipment 3


Alright that's allot of graphs, and we know graphs are not how we get views, so lets take tried and trusted top 5's for spin.

We will start with rapid fire round of nukes so.

Top 5 target nations:

• Germany
  
• Soviet union
  
• Japan
  
• USA
  
• England

Top 10 Target provinces:

• Tokyo
  
• London
  
• Berlin
  
• Hiroshima
  
• Moscow
  
• Nagasaki
  
• Washington
  
• Osaka
  
• Nagoya
  
• Paris

Top 5 countries nuking:

• Germany
  
• Soviet union
  
• USA
  
• England
  
• Italy

As we can see players are really not very imaginative with their nuke targets or they share a strange wish to nuke all the same places. Please also let me know why you really like nuking Paris in the comment below.

We can now take a trip over to something newer, its that new shiny toy the tank designer. I must say if there was a meta with tank design someone forgot to tell players because the only consistent design trend has been making cheap flame tanks.

So here we have your favourite modules for each category over the last month



How about your favorite Tank role designs, featuring some monster MBT design that players love.



You guys also have some erm "interesting" collective opinions when it comes to amphibious tanks.


We have also see that about 10% of you and only about 4% of total designs are made with auto design, this is something that reinforces our desire to improve this element of the designers.


Alright lets get into some more gritty details. first off we have been seeing how player designs have been changing since release in response to changes in patches and the design meta developing.


Next up lets see how you've been using those handy preferred tactics, it neck and neck over what players think is the best one for the army.


But you have a clear favourite for generals.


But what about all those new focus trees, well lets take a look at how you traverse focus trees. here we look at what exclusive choices you are making when playing with the new focus trees. As a community players will always trend toward the path that lets them expand and be independent so most of the breakdowns are as expected. however its also very useful to know what specific choices players make within these paths.








Construction now, when to switch to MIL's from CIV's is always an topic for debate. as we can see though the change happens on average quite early with the first year averaging at 13.17 CIV's built. This is consistent over most majors outside SOV, with many being much more extreme than the average.



Additionally you always need more railways and infrastructure.




Finally I'll bring us to Division meta. this might be surprising but meta divisions while definitely popular, are not as ubiquitous as online discussion would have you believe.



As you can see we have the usual suspects of the 10-0's, 7-2's and 14-4's but they are nowhere near dominant in the average game.
The situation becomes even less unified once we take support companies into account




That wraps it up for this Dev Diary, If you have anything specific you're interested in from this brief overview let me know and maybe we can do a deep dive in future.

- Added a Career Profile where players can view statistics about their playthrough
- Added promotion for the new DLC Subscription

We have two big things to talk about today so let's dive into it. First of all Hearts of Iron 4 is joining other PDX titles, and gaining an additional way to experience our catalog of DLC through a subscription model. If you have any questions about the subscription service, farther down the post there is a FAQ, and we’ll do our best to answer any questions you have in the comments.

Second, and unrelated to the subscription service, all players will have access to their “Career Profile” from the title screen in Hearts of Iron 4. This will track information about your time playing HoI, from this point forward. It will look like this!



And if you own any DLC (or are currently subscribed), you will be able to see per DLC additional info, as seen here by clicking on the DLC banners at the top.


The Career Profile is entirely unrelated to the subscription service, so ALL players will have access to these infographics just by playing the game. The Career Profile will be live tomorrow, Wednesday the 16th.




You need to own the base game only, then simply purchase game time from the Steam store page. There is also a button on the title screen that will take you there if you are not currently subscribed.


The subscription will give you access to Together for Victory, Death or Dishonor, Waking the Tiger, Man the Guns, La Resistance, Battle for the Bosporus, No Step Back, and cosmetic DLCs. Future releases will be covered in the subscription as well.


With a plethora of DLC options to choose from, starting out from scratch can be daunting to new players. This is an affordable way for players to experience the entire HoI4 catalog without having to weigh which items they would prefer to purchase. This does not mean it is the only way to get DLC moving forward. The subscription service is entirely optional, and buying DLCs as you have always done is still, and always will be available.


Nope! Nothing will change for you. You still own all your DLC and you still have the option to purchase future DLC.



If you stop subscribing, you will lose access to any content you have not separately purchased.



Canceling is handled through your Steam account. Visit Account Details, where you can cancel a subscription at any time. Your canceled subscription will remain active until the paid plan expires.



Yes! When new DLC and content packs are released, current subscription owners will have immediate access to them upon release.



That option is still available and always will be. The subscription service is an additional option that some players may find better suited to their situation. It is in addition to, and not instead of, a normal purchase.


If a renewable subscription has not been used during the current billing cycle, you may request a refund within 48 hours of the initial purchase or within 48 hours of any automatic renewal. Content is considered used if any games within the subscription have been played during the current billing cycle or if any benefits or discounts included with the subscription have been used, consumed, modified or transferred. More details can be found in Steams refund policy.
