Dev Journal #5: The Great Differentiation

[p]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?[/p][p]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.[/p][p]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.[/p][p]The result:[/p]

• [p]40 new units, unique per nation[/p]
• [p]Leader overhaul[/p]
• [p]AI personalities[/p]

[p]Let’s take a look![/p][p][/p][h2]Chapter 1: Unique Units[/h2][h3]The Historical Imperative[/h3][p]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.[/p][p]The challenge was to capture this essence with a game system that rewarded strategic depth while remaining authentic to history.[/p][p][/p][h3]40 New Units![/h3][p]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.[/p][p]That’s enough preamble. Let’s dig into the new units![/p][p][/p][h3]Ancient Era: Foundation Builders[/h3][p]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.[/p][p][/p][p][/p][h3]Bronze Age: Early Technological Pioneers[/h3][p]Bronze Age units feature some of recorded history’s first complex roles, where many disparate parts come together to create intimidating and efficient soldiers. Each reflects a pivotal moment for their nation when their military prowess was not easily opposed.[/p][p][/p][p][/p][h3]Iron Age: Classical Powers[/h3][p]Iron Age units come from a time when a nations turned into world-spanning empires on the back of military conquest. Units here are some of the most recognizable from human history.[/p][p][/p][p][/p][h3]Medieval Ages: Specialized Advantages[/h3][p]Units from the Medieval Ages are characterized by their increasing specialization and the ubiquity of common armament and tactics. Units here often represent simply the best of a type, units that are unrivaled even by units with the same arms.[/p][p][/p][p][/p][h3]The Renaissance and Beyond[/h3][p]As history progresses, armament and military roles have become more homogenized -but there are still some standouts. These nations may have to wait for their distinct advantage on the battlefield, but they say patience is a virtue.[/p][p][/p][p][/p][h3]History vs. Gameplay[/h3][p]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:[/p][p]✓ Historical Authenticity: Every unit was designed to reflect the genuine historical military innovations, equipment, and tactics that went into the unit.[/p][p]✓ 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.[/p][p]✓ 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.[/p][p][/p][hr][/hr][h2]Chapter 2: The Leader Overhaul[/h2][h3]Rethinking The Leaders of Ara: History Untold[/h3][p]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.[/p][p]Yet, there was a consensus that the Leaders failed to deliver on this promise.[/p][p][/p][h2]Leaders Reforged[/h2][p]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.[/p][p]Now to unveil our new leaders![/p][p][/p][h3]Harun al-Rashid[/h3][p]House of Wisdom

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.[/p][p]Let’s take a look at what we did:[/p][p][/p][h3]Personality-Driven Diplomacy[/h3][p]The new AI system abandons simple scripted behaviors in favor of complex personality-based decision making:[/p][p][/p][p]Relationship Dynamics by Leader Type[/p][p][/p][p]Advanced War Logic[/p][p][/p][h3]Cultural Development AI[/h3][p]AI civilizations now make strategic cultural investments:[/p]

• [p]Purchase Culture Traits based on the overall strategic situation[/p]
• [p]Invest in Regional Claims when territorial opportunities arise[/p]
• [p]Balance cultural and military development based on difficulty and personality[/p]

[p][/p][h2]Difficulty Scaling[/h2][p]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.[/p][p][/p][p]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.[/p]
