I know this probably has been said before, but I decided to post this anyways. It is evident that sometime in the next three years Hearts of Iron IV will end its development cycle (and it's very probable to be the next two). Obviously, Paradox Interactive's main focus as of posting this has been Europa Universalis V. However, once that game is released and the initial bug fixes are sent through, Hearts of Iron V will likely enter full development (they probably have already started concept work, etc.). This means that there will be a highly limited number of DLC left for this game. If I had to guess, we should expect 2-3 before they eventually allow the fat lady to sing and watch as the game sinks away in favor of a shinier replacement (unless they merge everything into one mega DLC). This leaves the question in the air, what do Hearts of Iron IV's future DLC look like?

So, I dedicate this threat to the one to maybe two people who see it and also wish to theorize. I am sure there are other threads like it, and I won't be surprised if no one sees this one. But, to anyone who decides to respond, thank you!

My personal theories on the matter:

1. One DLC will most definitely be a Japan and China rework. Considering the recent dev posts about changing how alliances work, it could be something that gets announced within the next few months. Having the Chinese United Front and Greater East Asia Co-Prosperity Sphere be two different forms of alliances would really work into a Japan/China rework's favor. And, Japan's current focus tree is one of the worst in the game. It is the smallest for a Great Power, and has the least amount of flavor.

2. A significant possibility would be a northern Balkans reworks. This could be folded into a final-goodbye-dlc (kind of like EUIV's final DLC) that incorporates other changes other areas like the U.S. or UK, but could also be its own flavor pack. As it currently stands, Yugoslavia's current focus tree is awful, especially for a country that played such a key role in the Second World War. And, both it and Romania's focus trees provide very little means of proper expansion. This is not to mention the presence of the worst focus tree in the entire game just to the North (that being Czechoslovakia's, which has been begging for a rework since the release of Death or Dishonor. People who think the old British Raj tree was the worst never gave Czechoslovakia a go. They can be fun, but their tree is ass).

3. Lastly, an Allies expansion is a significant possibility. While the American, French, and British trees are far more extensive than the current Japanese one, they are also smaller than their current German, Italian, and Soviet counterparts. This is another area where an alliance system change might be beneficial. But, considering that their focus trees aren't quite as bad, they will likely be placed on the back burner in favor of other projects. And, it is very likely that this would be part of a final-goodbye-dlc.

Anyways, that's all folks

Obviously, this year's DLC is about Japan and South-East Asia. IDK about China rework, maybe PDX will make NF trees just for Malaya, Indonesia and Thailand.
I'd like to have a French Entente rework. French monarchist branch is total shit. The same shit is Jugoslavija, Romania and Czechoslovakia.
And finally it would be nice to have Commonwealth rework. UK, Canada, South Africa and probably Australia.
The only question left is about USA. Should they get nerfed and reworked?

Definitely a rework for America, it's frustrating how weird some of their paths are, like a Confederate MacArthur

I don't know about the future DLC or future about HOI4.

The real rework that i would like to see is mechanism to form EU as democratic European countries.
There is something like this in the new GER alternative paths that works well (i tested that with GER monarchist path). But, with ie. France, it always seemed weird for me that you have to control territory of Benelux to form EU. Meaning that you must not defend them, must not be in an alliance with them (forgot joining Allies faction) and hoping that GER conquer them to be able to counter attack and take land control.
It's really counter inuitive as EU has been created on peace period by agreements after the WW2. But in HOI4, you need to control territory to do that. Well... Really ?

"Romania's focus trees provide very little means of proper expansion"

That is correct, actually just did a play through with Romania this afternoon. Puppet Bulgaria (focus tree), Conquer Hungary (said no to aligning) , Conquer Austria (just before Anschluss, conquer Greece (only have the wargoal, did not fancy war with Allies at that point), conquer Turkey, took all states in Yugoslavia with resources, joined Axis, beat Soviets (took land all around the Black Sea), left Axis, conquer Germany (enough points to puppet most of west Germany). Now going to switch to Communist and take on China and Japan, with later maybe the Allies.
And that with only 1 manual justification (Austria). And ok, the Soviets to take back core state.

To offer a counter-point to your argument, that is exactly what it took to bring Europe together on a path of cooperation.

Prior to WW2, almost everyone was either a proud colonial power with colonies and the entitlement of a major power, or they were a bitter loser full of resentment, trying to regain their old glory. Or a mix of both in most cases. Even after WW1 the colonial powers dug their claws deep into their colonies. Hell, in case of France they did so even post-WW2, and it took years of wars to have the French colonial empire crumble into dust.

Only when the horrors of WW2 brought so much death and destruction, only when the colonial powers were exhausted and released their colonies, only the knowledge that each new war would be more terrible and costly than the previous one, only with the nuclear arms race and the encroaching Soviet Union on the horizon, only then did a sphere of economic cooperation in Europe seem like a good idea.

So yeah, the pre-WW2 mindset was such that even a lower form of cooperation, like the League of Nations, was already an achievement. Forming the EU, though? Politically out of the question. Not unless you smash everyone to pieces in a brutal Blitz and dismantle them with years of war and occupation.

Agree with that. The problem is, even after defeating the Axis (end WW2), you can't do it because you are not controlling all territories. Because if you play as democratic country you want to free GER and ITA as democratic and obviously (if you join Allies), BEL, NL and LUX recovered their borders.
The only way to do it is to anexing everything. It's not really the idea of forming EU.
A new mecanic have been created with GoD for GER through focus and events/decisions. Let extand that in the same way for the other countries.

It may requires a decolonization of countries first though to be able to form EU. Never thought about that, but it seems a good way to keep it on the mood.

Yes, post-WW2 I agree with your take. Although I'll have to point out that HoI4 ends after that, and sadly has not much to offer beyond war. And I fear this won't ever get resolved, unless HoI5 includes the Cold War.

There is still SOV to defeat. :)
I usually stop my games after defeating SOV.
But yes, i hope for future an extention to Cold war. Probably in another version of HOI to avoid unbalance even more the current version.
 
USA does not happen unles Man the guns get integrated, France does not happen unless Le resistance get integrated…
So… maybe, but if anything like integration of one of those happens… we will know the next dlc…

Hey there,

Yeah, can't help but agree. As to the US, I personally think they should get reworked (and maybe slightly nerfed at the same time).

Yeah, fair criticism. I was thinking more in terms of core population and flavor rather than the later 2010's war goal focuses. But, they do technically allow for a means of expansion. Plus, mods like Road to 56 can be used to make the Romania tree less dated.

The bigger issue here is that there is zero idea on where to lead the HOI series.

Ok you want to develop HOI5.

What are you expecting to improve that will lead to better sales?

Improve realism (aka no more Luxembourg world conquest)? Then all the "fantasy" players will get upset that they can longer achieve their wet dreams.

Add crazy buffs to minors? TOA already tried that, and turned out "fantasy players" don't buy it.

Add graphics? Prototype vehicle pack wasn't taken well.

Add focus trees? Well GOE showed how well that flies.

Right now HOI4 is a victim to its own success. It needs to generate more sales, but really doesn't have anything to offer without deteriorating further.

Most recent dev diaries seem to be jumping between "let's get back to HOI2 with better graphics" (add Coal/Energy) to "let's just take controversial features from Victoria 3" (Power blocs/Faction improvements) or "let's do something half-baked but looks cool on paper" (MIOs).

Imagine what would happen if something like GOE was released as part of HOI5: the game would be irreparably trashed.

So when we talk about "rework China/Japan" yes, it's a great idea, but rework to what extent?

Give a better focus tree to Japan? But then US players will start whining "it's too hard to beat Japan" (UK Sealion being too hard, anyone?).

Same with China, Japan players will whine they can't capitulate China by 1938, killing their war conquest ambition. You gotta choose, but nobody wants to make that choice, hoping that somehow "Both sides will get appeased".



I would see the solution here to be a hard decision: get rid of "easy World conquest by minors" and focus on getting the game realistic. Not rigid historical, but a plausible realistic setting that gives a clear direction on where to improve on.

Alternatively, you need a HOI5 built around the Cold War with a completely different game design for economics, because the minors mana buffs accumulation for WW2 make the Cold War game plain boring.

When GtD was released, players LOVED how hard Sealion was. The forum was alive with excitement at finally facing a challenge.
