Ara Dev Journal #5: The Great Differentiation

Published on Thursday, August 28, 2025 By wasabi_md In Ara: History Untold Dev Journals

How do you make nations more unique?

When we began discussing Ara: History Untold 2.0, we asked: how do you make 40 different civilizations feel genuinely unique while maintaining strategic balance?

The answer went deeper than a few superficial differences. We discovered that giving players ways to leverage systems and explore new tactics yielded the most rewarding experiences. Distinctive traits and unique units give Nations personality and don’t just challenge the player to find new routes to victory, but to be on the lookout for their opponents' approaches.

This journal documents our journey through the systematic overhaul that transformed Ara from a game where Nations were largely cosmetic variants into a rich tapestry of truly distinct playstyles and historical authenticity. This effort became the single largest content expansion in Ara’s development history, and it’s part of a FREE update.

The result:

  • 40 new units, unique per nation

  • Leader overhaul

  • AI personalities

Let’s take a look!

Chapter 1: Unique Units

The Historical Imperative

Throughout history, civilizations have left their mark through military innovations. From the Roman Legionnaire who was more than a “better spearman”, to the Minutemen who earned their name as more than just an effective militia. While tactics, armament, and army composition often followed trends, distinctive and capable units could sway the course of a battle.

The challenge was to capture this essence with a game system that rewarded strategic depth while remaining authentic to history.

40 New Units!

Each nation featured in Ara: History Untold received a unique military unit, carefully researched and designed to be both historically accurate and offer compelling gameplay. While distinctive units are often only relevant for a tech era or two, properly leveraging them and taking advantage of their strengths can go a long way to securing a foothold in a game of Ara.

That’s enough preamble. Let’s dig into the new units!

Ancient Era: Foundation Builders

Ancient Era units come from some of humanity’s first notable organized military forces. Each reflects the distinctive geographical, cultural realities, and tactics utilized by their civilizations.

Civilization

Design

The Aztec Empire

Jaguar Warriors

Bronze Working

Brutal infantry that are expensive, but only require essential resources, making them reasonably accessible for some early-game rush strategies.

Hoplites

Bronze Working

Effective anti-cavalry units that can easily raise the combat effectiveness of any early-game military, allowing Greece to make resilient armies.

The Incan Empire

Andes Slingers

Archery

Kush

Kandake Guards

Bronze Working

Strong anti-cavalry units that are expensive, but boast an individual unit strength virtually unrivaled in the early game.

Bronze Working

Quick-moving anti-cavalry units, that when leveraged properly, can easily negate the advantage of cavalry.

Immortals

Bronze Working

Elite early game infantry units that are expensive to deploy, but seldom rivaled by other early game infantry.

Design

A terrifying ranged unit with a formidable range; fielding just two or three can grant the commander complete control of a vast swath of territory.

Some of the earliest gunpowder infantry that complement the widely available gunpowder range units, granting Spain a head start as the shape of warfare starts to change with the introduction of gunpowder.

Powerful gunpowder cavalry, the Cossack Cavalry provides a strong bridge between traditional cavalry and modern arms development.

United States

Firearms

Another distinctive gunpowder cavalry unit with a moderate maintenance cost, but a steeper recruitment cost. Their increased strength lets them remain relevant even as armaments rapidly improve.

Venezuela

Llanero Cavalry

Firearms

The llanero cavalry relies on traditional melee weapons in an age of gunpowder, but their mastery gives them a strength that can be difficult to contend with. Utilizing their speed and careful positioning is key to making sure they aren’t weakened by enemy volleys before they reach the battlefield.

History vs. Gameplay

Creating 40 unique units presented quite a challenge. Minor statistical variations could have achieved the base goal of providing unique units to every Nation, but that wouldn’t feel authentic or be particularly engaging. So when designing these new units, we favored:

✓ Historical Authenticity: Every unit was designed to reflect the genuine historical military innovations, equipment, and tactics that went into the unit.

✓ Strategic Differentiation: We sought to understand what made each unit distinctive and translated that into gameplay. Some units, like Samurai and Conquistadors, are slightly more powerful than similar units but at a higher recruitment and maintenance cost. Other units like the Hwacha Rocket Carts and the Tomahawk Warriors have advantages of greater speed or range, but are usually at some cost.

✓ Considering the Leaders: Units don’t exist in isolation; they’re a tool deployed by Leaders. So while working on this major content update, we also considered the leaders, their abilities, and their playstyles, and how the unit would fit into that leader’s plans. Legionnaires start as a slightly more reliable melee infantry, but when deployed by Julius Caesar, that minor bump in strength quickly benefits from the bonus Strength they get on leveling up. The Levy Spearmen become a key part of Sennacherib’s early expansion strategy to wage successive early wars without them becoming too costly to get an early start on empire development and accelerate the Golden Ages.


Chapter 2: The Leader Overhaul

Rethinking The Leaders of Ara: History Untold

The first clear choice any player of Ara: History Untold makes is who they play as. With 40 Unique Leaders, there are plenty of options that span ages and geography. Perhaps someone wants to emulate Alexander the Great and conquer the known world, or maybe they’d prefer to build up an empire of gold through trade with Askia Muhammad I.

Yet, there was a consensus that the Leaders failed to deliver on this promise.

Leaders Reforged

Since Ara: History Untold released, it has seen new leaders and a few Leader Feature and Leader Trait updates, but nothing on the scale of the 2.0 update. Every single leader was reevaluated and updated to capture the unique strategic doctrines and cultural philosophies that defined their roles in history. We wanted to avoid simple numerical differences or passive rewards. Focus was put on making Leader Features that rewarded and encouraged unique playstyles. Leader Traits were reassessed as a way to complement and reinforce similar playstyles.

Traditional, Sage, and Efficient give them unique ways to build up cities and become surprisingly competitive in ways other than war.

Chapter 3: AI Personalities

Getting the players to play differently from one another can be a double-edged sword. In the world of Reddit and Steam, you will see posts saying “AI is broken” because one of the AI players did something they didn’t like. But we’ve decided to plow ahead because we know, or at least hope, that most players will appreciate it if different AI leaders/nations play differently. Thus, you may make nice with Genghis Khan, but sooner or later, he will want to destroy you.

Let’s take a look at what we did:

Personality-Driven Diplomacy

The new AI system abandons simple scripted behaviors in favor of complex personality-based decision making:

Relationship Dynamics by Leader Type

Leader Personality

Relationship Threshold

Diplomatic Behavior

Aggressive (Genghis Khan)

700+ required for friendship immunity

30% reduction in positive standings, struggle to maintain high relationships

Peaceful (Tokugawa)

400+ sufficient for friendship immunity

Enhanced trade considerations, diplomatic stability

Balanced

500+ standard threshold

Moderate diplomatic approaches

Advanced War Logic

Factor

Weight

Impact

Relationship Weight

2x increase

Diplomacy genuinely meaningful

Trade Partner Protection

Non-aggressive civs won't attack

Emergent trade-based peace

Territorial Proximity

+30 very close, +15 nearby

Realistic geographical pressure

Human Targeting

Reduced from +10 to +3

Less "pick on human" behavior

Cultural Development AI

AI civilizations now make strategic cultural investments:

  • Purchase Culture Traits based on the overall strategic situation

  • Invest in Regional Claims when territorial opportunities arise

  • Balance cultural and military development based on difficulty and personality

Difficulty Scaling

We implemented a new feature called Adaptive AI, which we’ll be talking more about. But we have tried to make sure that it adheres to this system.

Bringing it together

There’s so much more we’d like to do. History is just such an amazing canvas to work with. But we are pretty confident that players will notice, very quickly, the changes we’ve made to make the players feel more distinct.
