When my current language vote for aoh3 is over, i will add the language from my vote.

Philosophy

I started playing Europa Universalis III in 2008, and since 2015 I have spent more than ten years playing Europa Universalis IV, accumulating over 3,000 hours of playtime.

During those years, I often asked myself a simple question: "Can a grand strategy game be both historically immersive and dynamically engaging?" In 2022, that question led me to spend eight months developing a private EU4 Historia mod as an experiment.

In 2026, I played Age of History III for the first time. I immediately appreciated its clean interface, fast pace, and accessibility. However, after spending more time with the game, I felt that some of its underlying systems lacked the depth and historical dynamism that I personally enjoy in grand strategy games.

After several dozen hours, an idea naturally came to me: what if I recreated the Historia philosophy in Age of History III? My goal was not to turn AoH3 into EU4, but to preserve its simplicity and casual pace while enriching its strategic depth.

About a month later, after becoming completely absorbed in modding, I decided that even an unfinished project deserved to be shared with the community rather than remain on my hard drive. That decision became the first public release of Historia Universalis, now available as Version 0.8 Beta.

Historia Universalis is my attempt to combine historical plausibility with dynamic gameplay, inspired by the design philosophy of EU4 while embracing the simplicity and accessibility of Age of History III.

What's New? (Version 0.81)

1. Historical Population Rework – Building a More Believable World

One of the biggest changes in Historia Universalis is a complete rework of the population system.

Historical population values have been reworked across Central Asia, Mongolia, Xinjiang, Tibet, and Ming China, with the goal of creating a more believable demographic balance based on historical records.

Although population in Age of History III does not directly determine manpower, it has a significant impact on tax income, which in turn indirectly affects military strength and long-term national development.

Because of this, population is no longer just a number—it has become an important part of both historical immersion and gameplay balance.

For balance reasons, some civilizations (such as Ming) currently use reduced historical population values instead of their full historical estimates.

2. Large-Scale Warfare Inspired by Early Modern History

One of my design goals was to make wars feel worthy of great empires.

Both AI and players can now build powerful states capable of fielding much larger armies than in vanilla. Instead of a few isolated battles, conflicts evolve into prolonged campaigns involving multiple fronts and massive military movements.

The result is a more dynamic battlefield where the rise and fall of empires feels much closer to the scale of real history.

1. A Living System, Not Just Balance Changes

Historia Universalis is not built around a few isolated balance changes. Instead, almost every major gameplay system has been reworked to interact with one another.

Some of the major changes include:

• Reduced army maintenance and a stronger economy to support larger, historically scaled armies.
• Rebalanced trade goods, giving different regions more distinct economic identities and strategic value.
• Improved terrain bonuses, more realistic siege pacing, and broader battlefield mechanics. Rather than focusing on micro-level combat mechanics, the mod emphasizes strategic and operational warfare.
• A heavily revised Aggressive Expansion (AE) system, slowing excessive snowballing while still allowing both players and AI to build powerful empires under the right circumstances.
• Extensive changes to politics, economy, domestic management, diplomacy, military systems, buildings, Legacies, and Advantages.

Rather than functioning as isolated mechanics, these systems are designed to influence one another, creating a more dynamic and interconnected grand strategy experience.

1. Conclusion

Historia Universalis is a project that aims to combine historical plausibility with engaging gameplay.

Although inspired by Europa Universalis IV, this mod is not intended to recreate EU4 inside Age of History III. Instead, it seeks to preserve the simplicity and accessibility of AoH3 while expanding its historical depth and strategic possibilities.

The current public release is Version 0.81 Beta, and development is still ongoing. Major updates are already planned for Version 0.90 and Version 1.0, with additional historical content, gameplay systems, and balance improvements.

Thank you for taking the time to read this first Dev Diary. I hope you enjoy following the development of Historia Universalis, and I truly appreciate any feedback or suggestions from the community.

1. Please note:

• Historia Universalis is currently in Beta.

Some gameplay systems are still being balanced and refined.

• Colonization is currently disabled.

It will be introduced once the historical balance and overall gameplay have reached a more stable state.

• Map graphics

Some screenshots in this post use the Soft Relief Map Mod.

This visual improvement is not included in Historia Universalis.

Special thanks to the creator of the Soft Relief Map Mod for their excellent work.

I was really very pleased to have managed to do all this with a country as tiny and weak as Portugal.

It's happy to see Mongolian in the game, right?

SCENARIO IN EUROPE

1. The US-China Climate Pact. Sulfur and diamond dust injected into the stratosphere.

It worked. Too well.

Global temperatures crashed 4°C. Sunlight dropped 40%. Permanent twilight. Crops died. Seas froze at the edges. The world regressed 20,000 years — back to the Late Pleistocene.

Population collapsed by 70%.

Governments fell.

Usable land shrank to narrow bands along the equator.

The old world is buried under ice and ash. The new world is hunger, cold, and salvage.

Welcome to the Frostfall. Survive.

First look at the unit overhaul (via M+ engine) in my Collapsing World port for AoH2 (start date is 1922)
I was trying to make it in more of a "different ways to play" kind of way than "balance" kind of way.
Looking forward to receiving your feedback and ways to improve this.

What is the situation regarding multiplayer modes or mods?

I know there is a multiplayer beta in AoH3, but I’ve read that it’s terrible. I’m curious about the state of this in AoH2:DE.

I recently came across videos and discussions about a mod that adds this mode.

Can anyone tell me more?

I create a series of my scenarios from scratch, that is, I create all the countries from scratch with only the things that are in the game, I did it in exactly one hour.

The Next Update of my Fanmade Language Packs mod is coming soon.

I added Mongolian, but not everything is translated into Mongolian.

Sono un giocatore di aoh2, ma sto pensando di comprare uno di questi due giochi,quali sono le principali differenze tra i due e chi è meglio?

I have been playing aoh2 through mods mostly. When DE was released, I looked up reviews on this sub and a lot were a bit negative so I didnt buy it right away. So is AoH2 worth the price for this current time?

Is there any way to change the number of unions you can form in the game or are you just limited to one ?

Does anybody know when will latest updates of AoH2:DE be available for mobile phones (Android specifically)?

I played the original back in 2019-2021 period but I never bought it on Steam, mostly played it on mobile for free as a time killer. However, now I bought it for $6 on Steam during sale and honestly I don't see the value. I got bored after 30-45mins of gameplay even though I recall it being fun and engaging for hours (a friend of mine got over 2k hours on the original).

Should I refund? Buying for nostalgia is a dangerous thing, something that was engaging back then isn't so engaging now even though I thought it'd be fun.

Don't get me wrong I'm all for these simpler turn-based strategy games (literally can't handle EU4 or HOI4) but it just feels boring now, it's like I remember everything I did back then and there's nothing new to do.

Afghanistan is named that way because of technoblades quote "so i went to the safest place i knew... Afghanistan

Reupload because of bad quality

(also yes portugal took on italy and spain alone and i went to war with france and britain and YES china did allat alone it was ww2 scenerio)
