Age Of Chivalry: Hegemony For Age Of Empires II

Age of Chivalry: Hegemony, is an unofficial expansion pack for the real time strategy game Age of Empires II: The Age of Kings which was created by Kor Bosch and Andrew Dunn. Age of Chivalry: Hegemony is, in fact, a mod pack which resets the game’s historical timeline to c. 1100-1500 A.D (the original timeline of the game starts with the Dark Ages, concomitantly with the Fall of Rome, and ends at the round of the Renaissance).

The mod features a brand new graphic system, new sounds, updated data, new modified AIs, as well as some other minor enhancements. It was released on the Age of Kings Heaven Community Site and so far it has over 20,000 downloads on the AoK Heaven website alone. The license of this software is freeware.

This new expansion pack depicts the history of Central and Western Europe from the 12th century to the 15th century. It also has a history section which describes (to a significant extent) a historical profile of each new civilisation added in the game.

In this new expansion pack you can notice a huge modification of the standard version of the game. This unofficial expansion pack replaces 18 previously playable civilisantions, along with their own unique units, technologies, and AIs. The newly added medieval polities are the following ones (in alphabetical order): Austria, Bavaria, Bohemia, Brittany, Burgundy, Denmark, England, Flanders, France, Friesland, Genoa, Guelders, Helvetia, Poland, Savoy, Saxony, Scotland, and Wales.

The installation requirements are the standard ones specified for both Age of Empires II and The Conquerors. Naturally, the player will firstly need to have the Age of Kings already installed on the PC prior to installing the mod. Moreover, the 1.0c patch of the official expansion pack (i.e. The Conquerors) needs to be previously installed as well.

Here are a few excerpts from the official article on ‘Age of Chivalry – a total conversion modification pack for Age of Empires II: the Conquerors set in Western and Central Europe 1100-1500 AD’ by the mod authors.

Although the graphic changes are being extensive, we’ve also gone for a total revamp of the gameplay. We’ve replaced all of the 18 civilisations, there are many new units, new, civilisation-specific buildings (the Princely Court, the Assembly Hall and the Guild Hall) as well as over a dozen new technologies, policy decisions, a mercenary system, new combat dynamics, and even an extensive history section. Yes, that’s right: we’re replacing all the civilisations in the game with new ones!


Wider support for scenario-only objects is included, and to showcase these a multi-scenario campaign is included with the mod itself. Multiplayer and random map balance has been tweaked, a rudimentary AI has been included, and with the new civilisations joining the mix, the European battles are even better!

– June, 2008

While graphics are concerned, the mod seems very realistic with respect to the architecture of the buildings. Even though it encompasses an interesting variety of brand new civilisations, unique units, and technologies, it has equally some disadvantages given the fact that there are some unsolved bugs.

Just to showcase a small example, when playing in the Random Map mode, picking Denmark as playable civilization in the process (the Aztecs or the Mayans were replaced with Denmark, these former civilizations being previously added along with The Conquerors official expansion pack) the player will notice soon enough after the game starts that when advanced to the Feudal Age the Town Center will turn into an Aztec building.

Below you can read the remainder of Kor Bosch’s interview from 2008 when asked about the origins of Age of Chivalry: Hegemony.

After we released the initial Age of Chivalry, which featured eight civilisations (England, Scotland, Wales, France, Brittany, Burgundy, Flanders, Friesland), New architecture we were happy to have finished that work. However, we quickly saw opportunities for improving the game even more as well as introducing new countries. Quite a few alternative set-ups were discussed, varying in scope and number of civilisations. Nevertheless, quite soon, in 2005 (!) we decided that we would mod the Arab civilisations to change into Guelders, Lorraine, Savoy and Genoa.


Choosing Sides


So, how did we pick our countries? First of all, we looked at geographic proximity to the countries already included. One of our reasons for starting the modification was the fact that games such as Koreans versus Aztecs held little interest to the historical gamer (at least to us) and so we would be hypocritical if our scope became too wide and we introduced countries unfamiliar to the other countries. Plans to include all of Europe were therefore quickly dismissed.


A prime requirement for the new countries was therefore that they had interacted with many of the other countries. This quickly ruled out the Italian states, which, being protected by the Alps, saw little military contact with Western Europe, excluding their mercenaries, represented by Genoa. Another natural barrier of note was formed by the Pyrenees. While we will not deny the involvement of the Peninsular powers in, for example, the Hundred Years War, the fact remains that they were on the periphery and north of the Pyrenees they generally fought in support of an ally, not to subjugate a country (excluding perhaps Charles of Navarre, but he was a bit mad).


The German principalities were the logical next step; we marked our border at Bohemia, which was necessarily included if only because of the Hussite Wars, which also marks them out as militarily unique. While countries to the east of the Empire were also considered, such as Poland and Hungary, these were quickly dismissed, because they had little contact with our Western European countries; the gap between, say, France and Bohemia was more easily bridged (and historically so – Bohemia and France held strong ties even before King John of Bohemia died at the battle of Crécy fighting for the French).


Customising the Game


When we were making good progress implementing the new countries, we looked for new ways of importing further realism into he game. After a lot of discussion and testing, we stuck with an ambitious new design. Among others, this split both the heavy cavalry and heavy infantry lines into heavy and medium unit groups, with the heavies trained at the Castle and the mediums at the Stable and Levy or Militia Quarters. When the medium infantry turned out to be typically not worth the money, we changed Halberdiers into Halberd Militia and made them the final upgrade to the Footman, a more realistic option considering the halberd’s past. Another major change included altering population counts for the higher quality units, like the heavy infantry and cavalry, the siege weapons and military vessels. This was a conscious choice to prevent any fantastic unit from dominating the battlefield, making those who invested heavily into, for example, a Scorpion defence pay the price for it.


Another altered combat dynamic came with archery units and light cavalry. Archers were, with a few exceptions, like English Archers or Genoese Crossbowmen, often ignored. We improved their combat use by giving them greater range, while simultaneously increasing their minimum range, which prevented them from shooting at nearby units. This made it all the more important for any archer unit to be well protected, because units closing in on them could have a field day and easily disperse them. To add to this feature, we increased the movement speed of light cavalry units. This was done because their speed was initially hardly different from that of heavy cavalry, making them less than useful. Their greater speed gives them an actual purpose – dispersing enemy ranged units and priests – while they are still incapable of holding their own against melee foes. And there are plenty of these for them fear, most notably the much improved pike formations.


The Final Hurdle


While initially changes to the original game were rather limited, our skills of manipulating the engine grew as work on the modpack continued. We learnt a few tricks, most notably the idea now known as the policy decision. This idea was developed when we realised the logic behind the technology tree: almost all units and buildings, minus the unique ones, Mounted Crossbowmen were by default available to all civilisations. However, a no-cost, hidden technology launching at the start of the game disabled all technologies and units Ensemble Studios did not want that country to use. We realised a similar technology could launch in the middle of the game, creating a whole new range of possibilities. We decided to create two such policy decisions for every country in the game.


Historically, we were lucky. The 14th and 15th centuries saw a lot of faction struggles within countries, giving us excellent staging grounds for our policy decisions, which would work best if they were more or less polar opposites. As we didn’t have enough time to research extensively initially, the policy decisions were made more unique as time progressed. For example the more urbanised states could originally choose between patrician or noble power, strengthening either militias or knightly units, but in almost all cases these have now been adjusted to be more unique, like the Saxon choice between becoming an electorate (Kurfürst) or joining the Hanseatic League.
