License production and map changes


Hi everyone! I hope you had a nice Easter break :) Today we continue showing stuff for the unannounced DLC and the Oak (1.4) update. For those who haven't been following, the main points of the Oak patch is to get some big difficult changes through for the AI, helping us with things that have long been problems, as well as make air warfare a much more pleasurable experience (more info on these in later diaries as they are still in progress right now). The main topics are License Production and changes to the map. Enjoy!

License Production
As we mentioned in the previous dev diary, nations will now have a new way of acquiring the equipment they need. If a nation lacks the required technology to produce what they need, they can request a license to produce foreign equipment, such as tanks, airplanes or guns, in local factories. Historically, this happened in various forms, ranging from full local manufacturing to assembly of foreign vehicles with or without adapting the designs to use locally sourced parts. The famous Swedish Bofors 40mm was extensively license produced and the Canadian Grizzly tank was a locally produced variant of the Sherman M4 design.

In the game, a nation with good relations with a foreign nation can request a license to produce the foreign equipment. The types equipment a nation is willing to license out is dependent on their relations. Germany, for example, may not be willing to license out their latest tank or fighter designs to other nations, but would be happy to provide Panzer IIs to friendly or neutral nations.



National Focuses will also be able to provide licenses, or provide bonuses to license production. In the last dev diary, we showed you the Romanian National Focus Tree. Some of these focuses references License Production, including the Acquire Fighters focus, which triggers the Fighter Competition event.



Producing licensed equipment will not be quite as efficient as producing your own designs, however. A cutting edge licenced production will have a noticeable output penalty, but a design a few years old will be almost as efficient to produce as your own technology. If you aren’t in the same faction as the owner of the design, you will also receive a little bit less technical support and manufacturing assistance.


Licensing equipment also give you a research bonus if you want to unlock making your own. This feature comes with the yet-to-be-announced DLC.

Map update
Different terrains are important, but it was not always as easy to see the difference between them as it could be. For Oak we have updated and changed map textures to make this much clearer. Particularly hills and mountains were in need of this, but forests also got a bump in clarity.




Impassable areas


A common problem that seems to pop up no matter how many times we think we have solved it is AI over-committing to Africa. There has been a lot of community feedback on this and we were hesitant to just make a hole in Africa as some mods do, but we still felt something needed to be done so we decided to go with a slightly different approach in Oak and have implemented a new kind of impassable areas. It's fairly realistic that large troop movements can not be done through Sahara in HOI4's time frame, so we have decide to block them off for troops and avoid any case where AI may be tempted to commit more troops there than what makes sense. It seems to help the axis AI out a lot and creates more interesting small-scale fighting for players as well. Right now there is no way to un-impassable these areas, but I feel like its a logical step in the future where people may be playing past the WW2 era to be allowed to do some expensive project and build a highway across.



We have also set up several borders as impassable to block passage across some areas of the Himalayas and others mountain ranges in that area (Afghanistan now is even tougher to take with more border choke-points like the Khyber Pass). While you can't enter impassable areas controlling surrounding areas will flip impassable states so if you control Africa it will look that way on the map also without say a hole in the middle.




Also don't forget to tune in at 16:00CET on http://www.twitch.tv/paradoxinteractive today where me and Daniel present the final episode of Paradox News Network (only true news!) dev MP with the Millennium Dawn mod.

See you next week for more diary goodness where SteelVolt will be talking about AI stuff!

Reflections and Romania



Hi everyone! After a few weeks break we are finally back with weekly dev diaries covering the 1.4 “Oak” update and accompanying DLC (you are going to need to wait a bit for the full announcement on that, but hey in paradox tradition we will still be talking about stuff that will appear in it).

Why have dev diary breaks?
Many people have asked why we take breaks in dev diaries at all, and there are a few different reasons.
  • People don’t like filler diaries, so if we don't have anything exciting to talk about it just means people not getting to read stuff they want and taking up the team's development time actually making stuff. I prefer not to make them if that is the alternative.
  • Being in a situation where you basically finish coding on the thing you talk about the day before is really stressful and can lead to showing things you have no idea if they work which leads to further issues, so we don't do that anymore. With 1.3.3 we were working into the last minute to add improvements and thus had no real chance to build up a buffer of content to talk about for a diary.
  • Several of the things we are working on are also very large things that take some weeks to complete, and it ties into the above. Two of these things are AI related and one is changes to air system as we said before the break we have been working on larger stuff for the Oak Update. Showing partial bits before all is in place is not very useful or easy for us.
Hopefully that makes things a little clearer. When we are quiet it's not because we don't love you, it's because we are working extra hard on stuff.

Lessons Learned
When we released Together for Victory, the feedback we got for the focus trees was somewhat mixed. On the one hand, a lot of people liked them because of their size and the ability to take a country down entirely new story lines. On the other hand, a lot of people felt that that the new trees wasn't adding much to the way they played. That was somewhat disappointing for us, because we had spent so much time on the hundreds of events and focuses that went into TfV, and we were wondering why exactly that was.

We started digging into telemetry data on what countries people actually played after TFV, and things got a lot clearer: About 40% of players play Germany, with other major nations following behind at quite a distance. The expansion gave the commonwealth minors a healthy bump, but still - the only content we really added for 40% of our players only happened extremely rarely in singleplayer games. Only when historical focuses were switched off, and the AI decided to go down the fascist path, did the German player get to see any new content (news events aside). And even then, the content was usually little more than an alliance request.

So that was the first big lesson: new content needs to tie back to major countries, particularly Germany. Thankfully, we had already decided that our next DLC should focus more on the Axis, so we wouldn’t have to try too hard to come up with reasons why Germany should be involved.

The other issue we noted ourselves was that the Commonwealth nations had very little interaction with each other. They each sat in their own little part of the world, mostly doing their own thing with their AI neighbours. That meant that even if you were playing one of the countries that got a new focus tree, you were surrounded by countries that still used the generic trees. All the interesting developments in your region were caused by you. We wanted to change that as well, and force you to pay attention to the world around you.

Which brings us to our first new DLC focus tree:

The Kingdom of Romania

Romania is a very curious country in the context of WWII, since they were - technically - on all three sides of the war at some point (and had the war gone on long enough, I have little doubt that they would have somehow ended up in the Chinese United Front). During the interwar years, Romania had made an alliance with Poland, and had historically been closely aligned to France. In the event, the Poles decided not to activate their alliance with Romania, in order to use the neutral state on their borders to ship in Allied troops and supplies.

This strategy did not fully work to Poland’s advantage.

Afterwards, Romania had to come to terms with German supremacy on the continent. This grew even more pronounced when France, a nation the Romanians had always considered as a model for their own country, fell to the Wehrmacht in just 6 weeks (claims that the French AI was broken have not been confirmed by historians). King Carol II approached the Germans for an alliance, bringing Romania into the Axis - but not after the Soviet Union, Hungary and Bulgaria had forced their territorial demands on Romania.

The Romanians supplied a large portion of the Axis’ oil supplies, nominally in return for German aid in modernizing their military. They also participated in the invasion of the Soviet Union, famously failing to hold the flanks of the German 6th Army during the battle of Stalingrad (in their defense, they had told the Germans it was a bad idea).

When the war threatened to move onto Romanian soil, the country switched sides again and joined the war on the side of the Soviet Union, expelling the Germans and carrying the war into Hungary.

In the game, Romania starts out in a fairly strong position, surrounded on three sides by countries that are either weaker or allied, and with the Soviet Union about to be concerned with itself for a while. However, her Army is fairly outdated, her industry is weak and those surrounding countries all have designs on her territory.

Romania’s tree is therefore centered around trying to maintain that territory. Historically, Romania followed a very flexible policy, negotiating with the Germans and the Allies in parallel, trying to get the best deal. This is represented in game by not locking you into an alliance branch too early. As long as you aren’t part of a faction, you can negotiate freely to get new technologies and equipment from the major powers (how you get that equipment will be revealed in the next dev diary).

Alternatively, you can be proactive and try to become the strongest power in the Balkans, surrounding yourself with a string of buffer states. That will require you to break with old alliances, but they were never going to help you anyway, right?



Romania also has several directions for how to develop its army, air force and navy:



Internally, Romania also had a number of issues, first and foremost King Carol’s attempts at steering the country. A devoted hedonist and a less-than-devoted husband, Carol was a constant source of scandals, while also considering himself the only person fit to run the state. You will have to learn how to handle him, which requires time and resources, both of which are in short supply. On the other hand, Carol has a unique new ability allowing him to recruit ministers at a lower cost. Whether or not you want to keep him around is up to you.


For people who like big pictures here is a link with the whole focus tree as one.

Increasing Immersion


Immersion from playing a nation is not just from events and focus trees, art and sound also play a role to create the right feeling and thus Romania gets new general and leader portraits as well as unique voice overs for Romanian soldiers and 3d models of famous planes and tanks


See you all next week for another diary! That one will not reveal another country, but showcase some other things....

“Hearts of Iron 4 wields complexity like a swift armor division during the blitzkrieg, allowing it to serve the idea of layered, cerebral, strategic warfare instead of letting it needlessly bog down the experience.”
9/10 – IGN

“It captivates me because—imperfectly, impressionistically, and perhaps a little amorally—it lets me orchestrate the most titanic armed struggles in history, from the fussy economic details to the cut-and-thrust of mechanized warfare. There are other great strategic-level wargames out there. But I have never played anything like Hearts of Iron 4”
8.8/10 – PC Gamer

“For now, after many dozens of hours, I'm taking a break from Hearts of Iron 4. Not because I'm sick of it; quite the contrary, in fact. What I need to do is some serious reading, some careful planning on what my vision for the United States should be in 1936. And when I've done that planning — when I've formulated my character sheet, as it were — I have the utmost confidence that Hearts of Iron 4 will be ready for me to play a role in world affairs.”
8/10 – Polygon
