HOI4 Dev Diary - Stability and War Support

Hello everyone! Today we are going to be talking about National Unity, or rather the fact that it no longer exists…

National Unity
National Unity first made its appearance in Hearts of Iron III, basically as a mechanic to make France surrender at an appropriate time (when Paris fell essentially). It was largely moved over to HOI4 unchanged. While it does accomplish what we wanted it's also a very restrictive currency to work with design wise. A player who is winning doesn't really care what their NU is, making a lot of focus choices meaningless in those instances (or almost, there is always that time your country gets blanketed in nukes and someone dropping paras on one of your big cities seals the deal in multiplayer). We wanted to model different nations better and make sure we could do more interesting focuses and events where picking a loss of NU wasn't always the better choice compared to giving up, say, political power. So what's the answer?

Stability and War Support
These are two new values shown in the topbar that replace National Unity. Stability models the people's unity and support for the current government. War Support on the other hand represent the people’s support of war and of fully committing to fighting that war. As an example Britain in 1936 would be a pretty stable nation, but with very low war support. A nation like France would be much more unstable and with equally low war support, while Japan would have high war support and also high stability (mostly due to the emperor’s influence).

Stability average is 50% and nations with higher stability than that gain bonuses to industry, political power and consumer goods. Once you drop below 50% there are penalties instead as well as lowering your surrender limit (although nothing as extreme as how NU affected things). Strong party support helps increase stability, but being in a war - no matter how well supported - is going to lower your stability. Stability also works to protect against coups against your nation as well.

War Support has several passive effects and also limits several of the laws. You can’t switch to full War Economy without enough war support for example.

Note that in the picture below France is getting +30% war support because they have been attacked by Germany. An offensive war on the other hand for Germany actually hurts their war support. This comes with some interesting balancing effects:
  • Democracies challenging Germany early over Rhineland etc would put themselves as attackers, forcing them to fight hindered by the war support penalty.
  • Fascist or aggressive nations will generally have more initial war support but are likely to be surpassed by democracies in a defensive war when it comes to war support.
  • Defensive nations will be able to ramp up army sizes faster due to mobilization speed while attackers need to play a bit more carefully. The return of “national pride” from HOI3 in the form of combat bonuses on core territory will help here too.
Speaking of mobilization speed, you no longer get a chunk of manpower instantly when enacting conscription laws or other changes to recruitable manpower. Instead how quickly the manpower is made available by the law change is controlled by your mobilization speed. The higher the war support the faster new manpower trickles in.

The air war also affects things as successful enemy bombing (or nuking) will lower War Support. Shooting down enemy bombers will offset this somewhat, as people are seeing you fight back against the enemy.

Here is an example on what can happen in a nation with low war support and low stability in a war. The severity of these particular options depends on exactly how low your stability/war support are. Here it's pretty bad.

For Germany a good way of raising war support is to pull off its diplomatic expansions without being opposed:

War support is also affected by how your allies manage. If a major ally surrenders it will lower your war support, so make sure to keep your friends in the war. On the flip side successfully capitulating major enemies increases your war support.

There are also some new ways to affect War Support and Stability outside events, ministers and national focuses that we aren't ready to show off yet ;)

See you again next week!

Mobilization speed? New modifier?
Anyone got any idea of what it might do?
It is mentioned in DD -

Very nice. Great work from the team on this, looks like a much more interesting and involving mechanic than national unity!

I you mainly talked about war support in this dd, will you talk more about stability in a later dd? For example what raises and lowers it, what impacts it has on other systems in the game etc.

Like others I want to know about that phone icon too! Also the extra tab under the factory counter that appears to have a number on it....
 
Will low war support force nations to the negotiating table (or face rebellion)? The UK came extremely close to this in 1940 so this would be cool and could pave the way for regime change mid-game.

Also, the option of "a pay rise in enlisted soldiers..." intrigues me - does this mean money is making a return?
 
What is the reasoning behind events like Anschluss raising war support?
One might say: "look we don't need war, we got/get what we want.", thus rather lowering war support.

Probably general support for the government/Hitler. Trusting them to lead and unite them toward a common goal- even through means of war.

It's more of a "The Western Allies are a bunch of cowards, if it comes to war we can take them easily and they will back down anyway"/"The Führer clearly knows what he is doing so if he says we need to go to war then we need to go to war"
 
Very cool update. Looking forward to how this changes the strategies. Especially the national pride sounds like a good concept

But...
If a major ally surrenders it will lower your war support, so make sure to keep your friends in the war.
Surrender? Do you mean capitulate or is there some info you are keeping from us?
 
I wished loosing convoy would affect support too. Which is directly affecting "trade". There is a reason British people kept improve its ability to defend against Grey Wolfs.
 
Is war support going to tick down every month being at war? Thinking about preparations to invade Britain/US can take a while, where we are uncontested on the continent, but because they are the faction leader, we cannot end the war...

The team is split on the issue of money. 14 out of 15 people on the team want money in. @podcat thinks differently.

The issue is that money played very little role in the internal economies. The Reichsmark was essentially monopoly money during the timeframe of the war. Inflation was an issue, but price controls and rationing could counteract that. Manhours spent is a far better value to assess the "cost" to the war economy of building weapons. For the purpose of paying soldiers, the government could always just print money, so in this particular event the effect is simply that it costs more pp.

Personally, I would love to get money back in the game at some point, but it'll probably be focused more on international trade where you actually had to pay in hard cash.

It was a big deal for Germany's popular support from it's people on how it was okay to invade our neighbors, it made the common people feel like Hitler knew what he was doing and they were destined for major power status in the world.
