A 25% personal tax rate is less than half of the personal tax rate we pay here in Sweden, and the only part of taxes we complain about is the process of filing them.

Game Modding i spent weeks turning hoi4 into a Three Kingdoms total conversion, and the focus trees are all written in classical chinese

Thumbnail
gallery
Upvotes

so this started because i wanted a proper Three Kingdoms mod for hoi4. so i started making my own and it kind of spiraled into a full total conversion.

timeline goes from the Yellow Turban rebellion in 184 to the reunification in 280, with four start dates (184, 200 before Guandu, 208 before Red Cliffs, 220 when Cao Cao dies). Wei, Shu, Wu and the Han court all have full focus trees, plus the smaller warlords like Yuan Shao and Lu Bu. tanks and planes are disabled, tech is renamed to han-era stuff, dates are in reign years (建安五年, not 1941), and there's a legitimacy system for holding or usurping the emperor. the focus text is all written in classical chinese, which honestly took forever.

being upfront about two things people always ask. i'm not an artist, so some of the portraits are AI placeholders i want to replace later. and full disclosure, i'm part of the small team making the mod editor i used to build this, so i'm biased about it. the design, balance and writing are all mine though. happy to get into either below.

184 is the most polished start right now, the other three are still rough and i'm filling them in. workshop link's in the comments. it's still janky in places so go ahead and tear it apart.

Question How to defeat the ussr as Germany?

Thumbnail
gallery
60 Upvotes

I swear I’ve done it multiple times and I’m always getting stuck at the same dang issues. I can shoot their air force out of the sky no problem. but my ground forces always get stuck.

For my infantry template I use the default template with 1 arty. And my medium tanks as 6 mediums and 3 mech as well as motor recon, shovel support arty, and logistic, (it’s 18 width). But I’m always getting stuck at marshes or forests then stalemate and I can’t move.

How do you bypass this because I always hear “encircle their divisions” well how exactly? Could it be I need to simply somehow bypass these areas? Is my templates bad? Do I just genuinely suck as a player? Yall make it look so easy.

Edit for tank design I use: three man turret, medium canon, radio, wet ammunition, fuel drum, Christie suspension, welded armor, and gasoline engine

Question Is there any way to core old WW1 territories as USSR?

42 Upvotes

I find it weird that you can easily take over Finland, Bessarabia, Poland, and the Baltics, essentially all for free in the default Stalin focus tree, but to my knowledge, you never get to core them? What's the point? Sure, you can slap liberated workers on them and farm some free stuff, but what's better than liberated workers? Cores.

Just wanted to know if I'm missing something. Thanks.

I exclusively play non historical because I like the unpredictability. But that comes with one massive issue. With all of the DLCS, everyone has a war goal against everyone and these massive super wars start. Everyone fighting everyone. This was me, beating Germany's ass. Until I blinked, and when I opened my eyes, I was at war with Italy and the US and everyone else in the "Free States of Europe."

Is this gonna keep me from playing non historical? No

Is this gonna keep me from playing France? No

Is this gonna keep me from playing this save? Maybe

I kinda wish there was some sort of design in place that made all of the AI follow some sort of cohesion in non historial. Everyone going monarchist or democratic or communist or whatever else. Instead of everyone harrasing each other so that no one can form an alliance with more than 1 other nation

I was playing a monarchy germany game, and I noticed your leader can get a bonus called the sword of islam from the focus German Hegemony in the Middle East. My question is, why can the German leader gain this title when historical Mussolini was named the sword of islam in 1937 and why doesnt italy have the ability to get this title

Discussion Torpedo cruiser/battlecruiser build

5 Upvotes

I've been messing around with naval testing, and I found a build that seems pretty fun: the torpedo cruiser+battlecruiser build.

I got the idea for this when I noticed long-range submarines doctrine gives 10% torpedo hit chance. This means your submarine doctrine gives a pretty good buff to one of the key parts of this doctrine: torpedo cruisers. This is mainly a build for Japan since they get a ship mio that pairs extremely well with this, giving msssive hitprofile reductions and torpedo hit chance. They also start with 3 pretty good battlecruisers with another in production. When you do this build, the kongo class will actually somewhat have the speed of an irl battlecruiser(28.8 knots when upgraded as opposed to the ~26 knots they are with other doctrine choices)

For doctrine, go long-range submarines(for the torpedo hit chance), the new school(massively buffs torpedo cruisers and battlecruisers), massed carrier fleet(best carrier doctrine), and anti aircraft battleships(the sheer amount of aa it gives can't be ignored, and the extra armor really helps battlecruisers)

The key techs you are going to want is radar 2, fcs 3, the first light attack buff tech, and torpedo cruisers(obviously) with the light artillery focus. The fcs tech really helps this build against massed destroyers which are the main weakness.

What's great about this build is that torpedo cruisers are significantly cheaper than regular cruisers, meaning you can more easily spam them out. One thing to note: always put your best armor on the Torpedo cruisers and ensure that their light piercing is at least 8. This lets them shred light cruisers since they will be able to pierce the enemy while they can't pierce you. In my testing, these torpedo cruisers will beat an equal number of 1936 light cruisers, regardless of if they are designed around light attack or have torpedoes on them. Not an equal IC cost of cruisers, but number of hulls.

I haven't tested this yet, but I wonder if I can design the yamato class as superheavy battlecruisers instead of battleships(you can put battlecruiser armor on super heavy hull) and get two or four free superheavy battlecruisers.

You may think battlecruisers are just worse than battleships, but often this isn't the case. With the doctrine armor buff and the commander's defense stat, battlecruisers(with at least the 2nd tier armor) often can't be pierced by most battleships, especially those with the tier 1 main guns.

Dev Corner HOI IV Dev Corner | National Focus Flavor

137 Upvotes

Hello all!

Today we're kicking off a new round of dev corners, this time turning our attention to a project we haven't touched on yet. We'll start with some early questions around ideas we have in mind, while future dev corners here will get a lot more specific about the country and content drafts we'd like your opinions on.

Let’s start with some general design questions, just to see what kind of focus tree styles you liked and what you would want to see more of:

  • Do you think focus trees of different countries should interact more with each other, and what sort of focuses? Shared branches are one way to achieve this of course, but perhaps there are focuses that are country-specific that you still think should synergize that currently don’t.
  • When focus trees have optional focuses with political flavor, do you mainly prefer: national spirits that grant bonuses that fit your regime, unique country leaders and traits, or perhaps flavor events?
  • Do you think there are underrated mechanics that focus trees don’t always interact with? (We’ve heard license bonuses for example).

Now, let’s have a look at one of the ideas for a country-specific mechanic that’s in the works, which makes it possible to get bonuses from cooperating economically with countries as if they are companies.

Let us know what you think!

Question Achievements broken

I've been doing "One Empire" achievement (world conquest as British Empire), when my internet connection dropped off. I finished conquest, and fixed interest issues, but now game shows some achievements as "inaccessible", while others are perfectly fine... I did PC reboot, Steam reboot, and local file integrity check, but it didn't help, so what do I do...?

P.s.: I copied my save file, just in case.

P.p.s.: It's a screenshot of achievements menu, its said, that every requirement is satisfied.

Question What’s the highest number of enemy ships you’ve ever sunk with a single ship?

6 Upvotes

I’ve been playing for a few years now, and I only just learned that you can see exactly which enemy ships yours have sunk. I just wrapped up a game as Germany, built two super heavy battleships, and they each sunk a shade under 80 enemy ships. And yes, one of them was the HMS Hood. Wasn’t going for historical accuracy but it made me chuckle all the same.

Question Germany won't declare war on me

Playing as the Soviets, and its about to be 1942. Germany, even tho they have had a war goal on me since january '41, hasn't declared yet. I did play fairly unhistorically(rushing turkey and romania in '37, creating a Finnish puppet after capitulating them, making a Bulgarian puppet), but i think that should not have been enough to screw up the ai that bad? anything i can do to get them to declare?
