HOI4 Dev Diary - Synthetic Dawn

Hi everyone and welcome back to a new dev diary. We are continuing work on the upcoming 1.5 “Cornflakes” and unannounced expansion. Today we are going to be talking about changes to synthetic refineries and resources.

Synthetic Refineries
Synthetic refineries are a great way to get access to oil and rubber for nations that end up on unfriendly terms with a lot of their neighbours (*cough* Germany *cough*). The technologies for them were however in need of some updating. Most people would only bother with the first to unlock the building unless they were a very small nation (and if so probably not a big consumer of those resources). It also felt unfair that nations that had plenty of one resource and lacked the other would need to do the same investment as someone who lacked both. Even if you had some of each, there was no good way of balancing output and you’d usually end up with a surplus of one or a deficiency in the other. To deal with this we now unlock 3 building levels at once, but the initial output of the refinery is much lower. We have then removed the previous 3 techs giving more levels and replaced them with 8 new techs that increase the output of your chosen resource. That means that if you only need more rubber you only need to research the Rubber Processing techs and can skip the Oil Processing.

Resources & Infrastructure
This is something we have been wanting to do for a long time. Each level of infrastructure now adds +10% resources in those states. This means that we can have resource amounts that actually grow later in the game. This should give you more reasons to upgrade low infrastructure areas to take advantage of the resources there, and will also allow bombing to impact normal resource gathering and not just refineries. A low infrastructure area with resources is now a great opportunity for expansion.

Together with this change we have improved the construction interface.

You can now see where resources are located and how much they are impacted. You can also see building slots which makes it so much easier to find the best places to build infrastructure without having to jump between map modes.

Resource mapmode now also indicates effect from infrastructure damage so you can spot potentially important areas for repair:

We have been rebalancing resource numbers across the world to go with this change. Numbers aren't done yet but I figure I’d spend the rest of the diary showing some areas to explain what we are working with.

British Malaya and Singapore are nerfed, but are both low infra allowing for a lot of expansion.

pasted image 5.png

USA has a lot of areas where investing in infrastructure will help them grow into a monster. Texan oil for example.

pasted image 6.png

As seen above, Japan has several opportunities to improve local resources now.

France generally got a bit of a resource nerf as it had a lot of very high areas and is also at decent infrastructure level.

pasted image 8.png

Northern Sweden still has precious tungsten which can be expanded to help Germa...accurately simulate Sweden's complicated role in the war.

Brazil now has the potential to be a true rubber king (is that even a word?) if invested in. Same goes for some other nations in south america, like tungsten from Bolivia.

This should shake up the resource play a bit we hope. See you all next week for more updates!

So if I'm understanding this correctly, we'll now be able to research more advanced and specialized Oil or Rubber synthetic refineries, but if we research too far ahead of time there's a greater risk of our synthetic refineries turning on us? I like it! It will add some nice late-game challenge for boring countries like Germany if they suddenly have to deal with the rise of the refineries. Plus, it's 100% truth-to-the-facts history.

Synthetic Refinery Level #?

its an area I would like more option. its a little odd that it applies equally to all. Not going to be a thing for 1.5, but its something we are thinking of solutions for.

Sure you couldn't postpone a bit 1.5 (which is unanounced yet) and include this ? It would be great to get it in your next build in order to be able to play a *real* game then...
Thank you for the great news in those recent dev diaries.
 
They also need to separate convoys from landing craft. I don't think they will do that either

Sure. I'm reading once again the Winston's memoirs and the landing crafts question is very big in his mind, and in the President' one too.
Nothing to compare with the game on that particular point.
*You wanna convoys ? Ok, i'll give you hundreds. Show back up in a few days.*

There is a quote somewhere about Eisenhower speaking about the war and "How we won". He very seriously credited Andrew Higgins and his Higgins boat for giving us the ability to undertake DDay.

Naval and amphibious warfare are modeled quite poorly in game. On top of that, the gameplay in both arenas isn't terribly engrossing either.
 
Yeah, I could see landing craft being separate from convoys - they're fairly important. They would have hamstrung any attempt by Germany to invade the mainland UK, and later in the war their lack would have hamstrung British amphibious operations were the USA not there to make up the shortfall.

Maybe you could still allow convoys to be used for amphibious operations, but have them be much worse at it than purpose-built amphibious craft.
 
Indeed, I really don't like the cheese of invading UK as Germany in the 30s. Making Landing Craft a thing would fix that. Im not asking for separate landing craft for tanks and infantry and the like. Just a separate research and production line to represent the additional effort.

I think in amphibious invasions not having landing craft should give a horrendous penalty--invading a occupied tile should be sure fire destruction. Invading an undefended coastal tile should still be able to go through.

A proper invasion should require convoys and landing craft.

Ideally, amphibious operations should have some sort of joint forces mechanic. I should be able to attach a fleet to my invasion force. They should help with sea zone control and should automatically provide naval bombardment when my invasion launches.

Were FDR and Churchil micromanaging the DDay plans (okay Churchill may have attempted to)? They likely were kept closely informed as to what was happening. But I doubt they had operational input as to the massive DDay time table for waves of invaders. Why do I need to micro the use of naval bombardment prior to invasion? Were there any amphibious operations during the war that didnt have a naval bombarbment prior to troops hitting the sand?
 
This is random and related to Romania's focus tree, but i will try to bring it to attention here anyway;

I feel that in the air focus branch of Romania's tree, the focuses "Air Superiority" and "Air Defense" should be switched. In my opinion it makes more sense to have "Air Defense" come after "Local Development"... you would develop your own fighters for achieving defensive air superiority and interceptions, which the Operational Integrity doctrine research bonus is ideal for.

The "Air Superiority" focus makes more sense coming after "Acquire Licenses" since you'd probably be with the Allies going that route, and they have the strategic bombers... which is where Strategic Destruction doctrine makes more sense.

Small thing, but i think it would help Romania's tree since I presume most people go "Local Development" for the IAR-80, but they waste the Strategic Destruction research bonus because they're already doing Operational Integrity doctrine.

I'm impressed you know so much specific information about HOI4 from just watching videos. :rolleyes:

This goes back to the idea of having shore convoys/small craft be in the game automatically from the get go.
 
If i remember correct my history classes, Brazil was approached by both USA and Nazi Germany for its rubber. We ended up forming a partnership with USA, which helped us build the CSN (a steel industry) in exchange for our rubber and some men to assault Italy.
than you should listen to this song when you play ;)
Arlindo Lúcio da Silva, Geraldo Baeta da Cruz and Geraldo Rodrigues de Souza – 3 Brazilian Expeditionary Force soldiers who became separated from their unit and fought a large contingent of Germans in Italy on 14 April 1944.

They encountered a unit 100 strong wehrmacht soldiers, but refused to surrender and fought to their last bullet and grenade. Once their ammo was out they fixed bayonets and charged fearlessly at the German position. The Germans buried them with full honours and placed a cross on their grave with the inscription 'Drei brasilianische Helden' (Three Brazilian Heroes)

I think if you locked naval invasions behind research you'd completely newter nations like Japan, who naval invasion is a major part of the game for them. If you give them the bonus from the outset you'd risk over powering a nation like Japan enabling them to take the islands in the Pacific too easily.
 
This you could easily fix through a research Bonus. Tie it to some Focus and you are ready to go, you could even give a 100% before time bonus like the Panzer III gets in Germany.

From a historical point of view what should be locked behind research and production is the ability to conduct contested amphibious invasions at any kind of efficiency.

Neither Japan nor Germany had any issues landing uncontested from normal warships or "merchant ships" when attacking the Southern Pacific or Norway/Denmark, but as soon as their landings met even weak resistance things quickly went badly for them ( Wake & Blucher ).

To be able to make contested landings to take back the fortified areas that Japan and Germany had captured though, the Allies had to spend a large amount of research and a large amount of production ( both on landing crafts and on vehicles to get over the exposed beaches ), and coordinate firesupport from warships and airpower.



So what I would like to see is the ability to use either convoys or specialized assault ships, just like you can choose to use either normal infantry or marines. If you land from convoys and meet resistance though, expect to fight at very low efficiency even if you have marines and at say -95% penalty if you land with infantry...

I don't know the specifics of the Japanese amphibious capacity, but I would imagine in the case of the Japanese and Americans, you would have foci for them, 50% on landing craft 1, insta 50 landing craft or whatever.

It seems too abstracted currently for an issue that was quite important, would solve an ahistorical issue, and could fit into a naval rework.
 
Japan's a tricky one. On the one hand, they have to be able to replicate their early-war successes. On the other hand, they never had particularly advanced equipment for it like the US and UK ended up with.

Maybe working an amphibious bonus into the light infantry doctrine would be better than giving them advanced landing craft tech?

Going from memory here, but Japan had some decent landing craft kit and doctrine (for infiltration landings, not head-on ones), and had them earlier than the British or the Americans. As well as a bunch of small landing craft (many similar in function to Higgins boats, although they didn't develop as far as the Allied landing craft), they also commissioned the world's first purpose-built landing ship (Shinsu Maru, launched 1935) which could launch landing craft (it could carry 20) through stern doors*. They definitely had the edge in equipment, technology and probably (but I'm not as sure about this) doctrine in the mid-1930s - but they were also definitely overhauled by US and Britain in equipment, technology and doctrine by about 1942/1943 or thereabouts.

* Edit: I started from memory - but by the time I got to this stage I'd meandered over to the bookshelf and looked this up - I don't know that by memory!
