HoI4 Dev Diary - Tech Changes

Hello, and welcome back to another Dev Diary for Man the Guns. Today, we will talk about some changes we have made to the tech and research system.

The biggest of which is, of course, the new tech tree for ships and other naval equipment. It is quite extensive, adding over 50 new technologies. Smaller changes and additions have been made to the armor and infantry tech trees through the addition of amphibious armor and to electro-mechanical engineering through the addition of Fire Control Systems.

Many of these techs do unlock new modules, but some do not - ammunition techs, fire control methods and damage control training amongst other don’t, and instead provide passive bonuses. This makes them quite valuable as you don’t have to build or refit a ship to make use of them.

The industry tree has also been expanded to accommodate fuel refining and storage. As one would expect, the new technologies improve the ratio of oil converted to fuel, giving you more fuel for the same amount of oil. The oil branch of the synthetic refinery tree no longer increases the oil output of each refinery but instead increases the amount of fuel generated by each synthetic refinery (synthetic refineries are not required to generate fuel if you have natural oil production!).

Since this adds quite a bit of research to an already pretty full research tree, we have taken some steps to offset this increase.

The first is that we have made a 15% increase to research speed across the board. The second is that a lot of the research in the new naval tech tree (as well as all the doctrine research) benefits from the research with XP system that gives you a fairly significant research boost if you have enough XP of that type to spare. For things like fire control methods and damage control training, researching without XP is significantly more time consuming to represent the lower effort spent during peacetime rather than learning from, well, experience.

Lastly, we made some changes to how research bonuses are granted and how ahead of time bonuses are handled. Regular research bonuses are no longer reducing research cost but instead boosting research speed. A previous 50% reduction in cost is now a 100% boost in speed. Ahead of time bonuses have been changed to apply a flat reduction in years rather than a reduction to the penalty, so a 1944 tech with two years of reduction would be treated as a 1942 tech for the purpose of calculating research time.

That is all for today. Next week, we will take a look at some of the art and music coming in Man the Guns.
 
Alright Im a bit sceptical right here.

Because these techs are nice and stuff but what does it contribute to the overall picture?

We all know our history very well, and Germany's focus on navy drained a lot of resources that could be used else where like the production of tanks and airplanes. Even more with the addition of fuel. Why would the German player even invest in the navy if it cost so much tech and resources with little gain?
 
if there is a proper place for this(these) requests please help me see that it gets there.

because this update is going to have a lot of major changes, can i ask for just a couple simple (i think) cosmetic changes that would go a LONG way for flavour?

1- for countries (say brazil) who have no images on fighters, tanks etc, can they get a similar generic flavour? like british, or french?
kinda like how artillery is setup.

given the number of countries you're adding it would go a long way if you chose to play one of these small upstarts.

2- no more generic no pic generals! please?

recruits 4, gets 1 that has an image :(
i think those are easy asks and removes the 'black planes of death'

3- make turner valley focus available to all tiers of canadian (or any nation that relies on oil - now also fuel) governments?

why cant commrade canada or the unitarians get what would be in the dirt already, regardless of territory owner.

great game. many loves.

No but Japan might be interested. Oh and Italy if they want Africa. Which might piss of the British.

And that's not counting the U-boats which definitely had a gain. Which also definitely pissed off the British and the USA.

Edit - oh and if you can keep the USA and Britain focussing on naval tech it eats their research budget so they don't have tanks and planes which might make it hard for the Allies to invade Europe till later giving you more time to deal with the USSR (and lots of land xp to get through the doctrines quickly). You just have to invest enough the opponents are forced to out spend you.
 
Please release soon :) Or at least long before Rome releases
 
@Archangel85
15% faster research equals 15% more interruptions in the gameplay to pick new research.

Is there any chance that we could get a research queue? It could simply be done for each slot separately, so that it wouldn't offset the balance. I for one would love to create a long queue, rather than having to interrupt the gameplay flow too often.
whats? its like play s.t.a.l.k.e.r. and wish stop the game to look inventory.
you just have the clock time to pick of a mounth if you want make a mod and extend this time, i dont see why you wish to make that thing.

Yeah, but the combined navy of UK and US is more then enough to kill of the Japanese fleet, so then again? why would anyone focus on a one sided naval combat.

Depends how things go. In HoI4, Germany and Italy have a good chance of destroying the British fleet or making Britain capitulate long before the US enters the war.

In any case, it's a war, and attacking an enemy's weaknesses forces them to divert resources to counter the threat.

If Germany focuses on convoy raiding, the UK has no choice but to try and stop them. If Germany ignores the sea entirely, the UK can spend all its resources bombing them instead.

Okay, on the one hand, you kind of have a point. Historically, the US fleet and British fleet are so powerful that there is no practical way that the Axis/GEACPS ever wins. The USA in real life fought Japan largely one on one, with one hand tied behind its back, and still had them on a permanent defensive inside of a year or two; Britain alone had a similar effect to Germany, which never had any realistic means to put Operation Sea Lion into effect.

But then this begs the question...why are you playing a WW2 game? You can make it so that these things are ironclad truths that Germany can never practically overcome, but then there is no point to playing the game, because the war has a foregone conclusion. You can look through my post history, I am definitely in the forum faction pushing for greater realism in the case of all of Paradox's games, but I'll concede at least that there has to be a game to play.
 
Will you guys be changing the DDS icons for Aircraft Carrier tech or add unique Icons to Japanese or American Aircraft Carriers? :)
Quite frankly i find the current Icon that represents carriers to look too much like a "box" and they honestly look ugly... :confused:
 
So excited for this expansion!

It might be a silly question, but what does the Army / Navy / Airforce experience boost actually cover? Only the Army / Navy / Airforce doctrines + equipment? What about industry and research, can we boost that with something?
 
So stupid question. I count four distinct paths for gun armament modules. Does it break down into light, medium, heavy, and anti-aircraft?

As for the question of why you would pursue building a navy when it appears that the effort involved would be a sub-optimal use of time/resources the answer is because it’s fun.
 
@Archangel85 A few things I would like to know and I hope you could answer but it would be understandable if you couldn’t. How is the United States of America focus tree going and what countries might receive graphical changes besides Mexico and the Netherlands (sorry but the new leader portraits and unit models are making the ones on the major countries look terribly out of place)?
 
Super Heavy Battleship.

Only on the 1936 heavy hull? I was going to say that "the Yamatos blah blah," but Wikipedia DOES tell me that their design started around 1934-1936... Though Wikipedia does say that the Montana class started design in 1938.

Will they exceed the Panamax (i.e., be too big to use the Panama canal)?
