HOI4 Dev Diary - War Changes and Game Difficulty

Hello everyone, last week we covered the last of the new focus trees, so from now on we will focus (heh) on new features and changes again. Today we are going to start off by talking about changes to how wars work as well as sharing some very interesting telemetry data!

War Changes
When we planned out Waking the Tiger, we knew that we wanted to solve several issues with wars once and for all. The game wasn’t really set up for 3-way-wars and it tried to stop you from 3-way wars as much as possible, and if it failed some pretty nasty bugs could happen. Wars could in certain cases end up either having to force friends into war, or drop people from wars which usually really messed up both multiplayer and singleplayer when it happened. It was all just a nasty and horrible mess on the code side as well.

Our changes effectively mean that now every two nations at war have their own little war and we instead present wars as a summary of sides that make sense. How you look at a war as a player shouldn't really look any different now. This was a massive change that has taken us a lot of time (and quite a bit of sanity), but I am confident that it will have been worth it with all the issues it has solved and freedom for players it will enable (particularly for mods that like to do a lot of wars from events and focuses where there was a big chance of things working out wrong - not naming any names).

When playing, the biggest changes you will notice is that wars merging now is a lot smoother. War score, casualties and such are properly tracked and retained. Its now also possible to fight 3-way wars (or more) so we can handle Axis vs Comintern vs Allies vs The Japanese co-prosperity sphere etc.

The war interface has also gotten a bunch of changes:

  • You can now filter nations like minors, capitulated, or nations who aren’t called in yet
  • We show nations that could be called in, but aren’t in blue (so you can see that the soviets have not called in Republican Spain yet), this is instead of the old interface where there was separate lists, now a button appears if you yourself have the power to call them.
  • We group up factions and summarize stats for them for easier comparisons
  • The interface lets you pick among your wars, but there is also a War Summary that collects all war allies and enemies in one big page. The interface also scales with your screen size, so it's much easier to get an overview of large complex wars now.

One of my favourite new things is that we show a breakdown of the casualties, so you can see how many casualties you caused for a specific nation:

Difficulty Settings
We are slowly building up better and better telemetry on HOI players and I really love to share it with the community when it’s surprising, and this one surprised me a lot actually! It turns out that close to 40% of players prefer to play on the lowest difficulty setting. I would have expected this to be quite a bit less!

As number of hours you play goes up people migrate away from recruit a bit. So for players with less than 50 hours played, 60% of them use Recruit and after playing 200+ hours only about 28% still use Recruit. Veteran shows the largest relative change. For beginners, it is 1.4% who use it and it goes up to 3.5% for 200+ hour players. The vast majority use Regular. It's the difficulty setting that doesn't give you any bonuses or penalties so this is usually what people prefer. My design philosophy is to try and stay away from direct combat bonuses and such that will make you learn the game in the wrong way. I prefer buffing things that allows a player to play more sub-optimal, so faster research (or slower so you must make more optimal choices), smaller losses on efficiency when changing production lines or less impact of lack of resource and such. It's also important to only affect the player as you don't really know which of the nations will end up on their side or as enemies. For example, in HOI3 depending on country it could actually be easier at harder settings, since certain nations were advantaged by that in an allied role.

So what are we doing about this? First of all we are adding two more settings (the gods of symmetry demand it!). A new difficulty before Recruit called Civilian and a new harder difficulty called Elite.

I also thought I would mention that we haven't really analyzed the custom difficulty settings yet but plan to in the future. I always recommend them to tailor your game. Say if you want a particularly strong Soviet to fight as Germany.

See you all again next week! Also don't forget to tune in to World War Wednesday at 16:00 CET where we start a new campaign to show off all the new stuff in Waking the Tiger as a Chinese warlord on the rise!

Rejected diary titles:
  • Dan Lind's "War and Peace (Book One of Four)"
  • War (screen), What is it good for?
  • I guess we don’t need to spend all the work we do on improving the AI after all
  • War. War sometimes changes
  • You can't fight in here. This is a wargame forum.
  • Players online usually lie about the size of their conquests
  • You get a war, and you get a war! Everyone gets a war!
  • Maybe finally Quill18 can now play competitive multiplayer without getting shafted by a war-merge bug!

So which difficulty setting is a "normal" one without any penalties nor bonuses?
 
Paradox said "shit" :eek::eek:

Anyway, for a WW2 wargame this dev diary was REALLY necessary, loved the new model.

Question: Will World War 2 be called that instead of "German-Polish War"?
 
And please give us a release date! What else is left? :-D
There are a few things more to reveal :) We have done all the features now and are working on polish and ai and balance.

Can you please fix the Multiplayer bug which allows ghost chatters to spam the lobby;
its probably fixed. We solved it the other day but QA hasnt done full tests on the resolution yet so not going to dare 100% confirm ;)

ah ok i missed that, oops
are we going to get an AI dev diary before release @podcat ?
Yezz

Do/will casualties caused count towards a nations war participation score?
And will you be re-working the entire surrender/peace/peace-conference mechanics at some point in the future?
Its part of our long term todo list for sure yea. but not for Tiger. its a massive undertaking

Cool! Any changes to the strenghtern nation stuff? It'd be cool if you could boost minor nations as well.
@podcat hey, is it possible add one more checkbox for difficulty settings? Something like "powerful minors" that will give bonuses to minors or will make them use a beefed up focus tree. I always play minors as I hate to play major, it's just not that engaging for me, and I would like to see them making more impact on the game if I don't want to play with historical focus.
I hadnt really thought about this but I guess it could be good to have as well. its a little tricky because of the amount of them. The way I think about stuff I eventually want to have something more like game settings for Ck2 etc where you can customize a lot abotu the game. This would be a fit there.

Maybe the war screen could tell you when the war started?
I guess as well as when you joined. although at that point getting a full history of joinees would be nice too
 
Have you guys at least fixed the surrender mechanics where one side has an 80% warscore and yet is unable to compel the other side to surrender?

And could you clarify if you could or will make casualties caused as part of the war score?

I think that a quick workaround before you get to make a design and stuff would be to simply put all the nations on that strenghtern list, majors first and minors after them alphabetically. Modding-wise,it wouldn't take long and it would do alot of difference :)
 
When you get to analysing country custom settings please consider adding more customisation.

As Germany I always buff Soviet; USA and UK
Anybody else I significantly buff Germany.
Yeah, once we have sifted through all the data and come up with some popular combos (I bet there are) I think something like "suggested custom difficulty for <Your Nation> would be great so you dont have to keep setting it up

Do theses war changes meant that in future separate peaces/more peace options will be possible?
its much more possible now as we have done a lot of the heavy lifting required. Before removing nations and such was just extremely error prone

So which difficulty setting is a "normal" one without any penalties nor bonuses?
Regular, like before.

I'm looking into this a bit. I would like to port over the system I made for Vicky 2 one day as it had a lot more flexibility. HOI however needs way more point of view logic or you will get very wierd names so we will see. Some day for sure, but dunno if its gonna be in for 1.5. if it does I will write it in a diary though :)
 
A new difficulty before Recruit called Civilian and a new harder difficulty called Elite.
Will "Recruit" be the new "no bonuses, no penalties" difficulty setting? Or is it small bonuses? Considering that "Regular" now poses small penalties, I have to imagine this is the case. I would like to retain the ability to have "no bonuses, no penalties" difficulty setting.
 
And could you clarify if you could or will make casualties caused as part of the war score?
We havent changed warscore calculations, only bugfixing. Not going to change for 1.5, but perhaps there is some justification for mixing it up now when its more visible so its a % of your scoring

On that subject, are there any plans to revise the Poland focus tree like you're doing with the majors?
Maybe one day? Some of QA who like poland are playing with changes in their spare time, so it could happen sometime :D Poland is actually pretty popular

Sorry its my fault for unclear screenshot. note how tooltip is on Veteran. Regular is still default and has no modifiers
 
How do these new difficulty settings effect achievements? I know not a lot of players go for them, but for players that do the new regular settings are horrifying.
thats it, going to make a new screenshot for the setting now ;D everyone seems to be confused by it

Maybe there could be something like triggered modifiers that do one-off changes to war names, eg

Code:
aggressor = {
original_tag = GER
has_government = fascism
}
defender = {
original_tag = SOV
has_government = communism
}
do_effect = {
change_war_name = GREAT_PATRIOTIC_WAR
}
 
Considering that "Regular" now poses small penalties
Look closer:
I havent, you just cant see the mouse cursor in the screenshot ;D the tooltip is for the updated Veteran level.


And asking again in case you missed it, but does the patch contain a name list for Japanese divisions? I want to translate it from Japanese.
Besides Germany, how many other countries have a custom-tailored division name list now? I discovered some first-hand material on the historical IJA division name list (here) and I'd be glad to to translate it into English, but I don't want to waste time reinventing the wheel if you have already done theirs.

yeah japan has a custom file. A lot of nations do actually. I cant give you an exact number right now without needing to go though all of it :D I can check up on it for later
 
The -20% PP on Regular meens that France and the USA will get -PP till they get rid of ther specific debuffs... a bit harsh
Plus this meens that you now get a average of 0.6 PP per day .... in a DLC wher PP will be very important ... you need all that PP for your Decisions.
Well I suppose ppl will play on Recruit even more
The tooltip is for veteran - you can tell because it's slightly lighter than the others. That said, it IS pretty hard to tell due to how small the difference is and the fact that regular is selected.
