ヨーロッパ・ユニバーサリスIV - 開発日記 15 - ブルータス、お前もか?

Welcome to another development diary for Europa Universalis IV!
So far, all of the national profiles we’ve given you have focused on the big boys - the major powers that people tend to start with when they play a new game, and that have the greatest potential for world spanning empires.


But the Europa Universalis series has also attracted a lot of people that want to spend time with smaller countries and see what they can do.
This time, we turn our focus on a country that is on the 3rd tier of importance for development to show the attention they get.
So welcome to Milan, a flat territory where sultry summers and cold, rainy winters prevail. Situated in Northern Italy, the Duchy of Milan is a part of the Holy Roman Empire and includes allthe former towns of the two centuries dead Lombard League and holds the wide rural area lying between the hills of Montferrat and the Venetian Lagoon.


Milanese Possibilities

In the mid-15th century, Milan was pretty much constantly at war with its neighbors. This was the high point of the condottieri wars that ravaged Italy for a century - pretty much until the French invaded and started smacking everyone around. So expect Northern Italy to be a bit of a cockpit.


The Lombard plain’s greatest advantage is that Milan can create a lot of wealth for a nation that starts the Grand Campaign with three provinces. Its cloth and wine are high value goods and it has easy access to trade nodes dominated by both Genoa and Venice - meaning that if it chooses to invest in a merchant fleet and can win some battles at sea, it can reap the wealth of these trade routes.


If you dare to choose to play Milan, you might find that you need to defend your territory against the Swiss, the French and the Venetians. It´s hard work, but someone has to do it. In your favor, France and Venice have bigger fish to worry about in the early going (though they will naturally expand towards Italy) and Switzerland has to cross the Alps to do any damage, and this takes time. If Milan chooses to go aggressive, the smaller city states of Italy (Mantua, Modena, Ferrara) are close at hand, and if Florence falls, Milan is well on its way to becoming the premier power on the peninsula.


The Flavor of Milan

In Europa Universalis II, the last game in the series that really invested in historical events for the player to engage with, there were two events for Milan: one where they could get inherited, and one flavor event about Leonardo Da Vinci. However our goal with Europa Universalis IV has been to make sure that not only the ten or fifteen most “interesting” nations had flavor.


At the moment, Milan has ten historical flavor events, none of which are a forced inheritance. One of the most interesting one is the Ambrosian Republic, which can be triggered during the first century of gameplay.
In 1447 Filippo Maria Visconti, Duke of Milan, dies without a male heir which brings the Visconti line of rulers to an end. Now, the Ambrosian Republic enters the stage. Historically speaking, this was a short-lived popular government that resisted foreign invasion until it was toppled by one of the great Italian soldiers-of-fortune, Francesco Sforza.


In Europa Universalis IV, if Milan has a regency or low legitimacy you can choose to institute the Ambrosian Republic in Milan. This action will give some large neighbor’s a Casus Belli (Just cause for war) on you so they can restore the monarchy, while you get a unique government form that gives you increased morale for your soldiers and greater tax income.


Of course, Milan can still form the nation of Italy as all Italian minors can But they need to dominate Northern Italy and Rome to do it.

そして当然のことながら、ミラノは今回も他のイタリアの小国と同じようにイタリア統一国家を設立することができます:-) しかしそのためにはやはり北イタリアとローマを支配する必要がありますが。

Milanese National Ideas

Milan starts with the tradition of +10% infantry power to represent their formidable condottieres, and a +1 bonus to diplomatic upkeep (a concept we'll talk more about in a future dev diary).


Renaissance Prince 10% cheaper Ideas
Patron of Music +1 prestige yearly.
Lowered Power of Barons 10% more tax
Age of Condottieri 25% cheaper mercenaries.
Encouragement of Philosophers - 5% cheaper technology
Merchant Princes +10% Trade Power
Rulership of Enlightened Principals 10% cheaper stability.


And when you have gained all your national ideas, you get a bonus 20% to your manpower.


Not every minor nation will be getting unique National Ideas - most will get a generic list of bonuses. But many popular and important minor nations, from Bohemia to Vijaynagar, will give you a chance to play smaller powers that don’t sacrifice anything with regards to personality or variety.


Bonus Detail: Republican Tradition

In the Heir to the Throne expansion to Europa Universalis III, we added the concept of legitimacy for monarchies. The idea was to find a way to model the transitional period between new monarchs or new dynasties and make the royal marriage system a little more important. This created some interesting mechanics, and we felt we needed something to serve the same purpose for Republics.

EU3のHeir to the Throne拡張セットから、私たちは君主制の正統性という概念を導入しました。新しい君主や王朝への移行期間を具体的に表現するための方法として、また王室の婚姻の重要性を少しだけ高めるためのものでした。これによって、いくつかの興味深い構造が発生しました。そして私たちは共和制についての同じ目的のために何か提供すべきだと考えたのです。

So, in Europa Universalis IV we have now added the concept of Republican Tradition. This is a value between 0 and 100%, and a newly formed republic starts with just 1% tradition ? people like what they know, historically republics were seen as a little bit unstable, and it takes time before the ideas of civic freedom and voting for leaders take hold. A low republican tradition increases stability cost, and a high tradition reduces revolt risk. If you get a low republican tradition, you are more likely to have rebels supportive of restoring the monarchy, and if you ever go below 1% tradition you convert to a despotic monarchy rather quickly.


Your Republican Tradition goes up by +1% each year, and there are events that can give you a hard choice between tradition losses or other negative consequences. There are some advantages to playing a Republic ? you get to choose your leaders in elections, after all. But you should never be really comfortable.


In light of adding this new mechanic, elections for Republics have changed slightly. You will lose 10% Republican Tradition if you re-elect the same leader, to represent the fear of a republic losing that regular change of office that guarantees the legitimacy of the government, and if you re-elect someone at while you have low tradition (currently we’ve set this at less than 20%), your Republican period comes to an end and you give birth to a despotic monarchy.

We have countries in 4 tiers, when it comes to attention in the EU4 development process. This is for DHE, decisions, missions and (unannounced features and mechanics).


Tier 1 - 8 countries (flavour and fun, behaviour vital for game progress)
Tier 2 - 9 countries. (flavour and fun, behaviour important for game progress)
Tier 3 - 16+ countries (flavour and fun, behaviour not vital for game progress)
Tier 4 - the others.... where the minimum flavour level is EU3+EU2.

最上位グループ ‐ 8か国(味わい深く面白い、ゲーム進行上必要不可欠な役回り)
第2グループ ‐ 9か国(味わい深く面白い、ゲーム進行上重要な役回り)
第3グループ ‐ 16か国以上 (味わい深く面白い、ゲーム進行上必要不可欠というわけでもない役回り)
第4グループ ‐ その他全て…EU3と2において最低限のフレーバーしか用意されていない状態

Tier 1

1.England - Arguably the winner of the time period.
2.France - Big blue blob is a must here, no game is complete without a strong France dictating western Europe.
3.Ottoman Empire - the major complaints on EU3 was the fact that they didn't become the historical threat they were.
4.Castille/Spain - We all want a big Spanish colonial empire on the map.
5.Muscowy/Russia - another failure of EU3 was that russia didnt form often enough, and you ended up with a fractured east.
6.Sweden - Swedish agression is what shapes the northeastern quarter of europe.
7.Portugal - in history and with our new trade system, their impact in the first 2 centuries changed europe forever.
8.Austria - The central european player that affected half of europe.

1.イングランド ‐ 間違いなくこの時代の勝者。
2.フランス ‐ 青くてでかいヤツはここに居るべき。西ヨーロッパに多大な影響を与える強力なフランスが無ければこのゲームは成り立ちません。
3.オスマン帝国 ‐ EU3のよくある苦情の一つは彼らが史実のような脅威にならなかったということ。
4.カスティーリャ/スペイン ‐ みんな地図上にはスペインのデカイ植民地帝国があって欲しいでしょうから。
5.モスクワ/ロシア ‐ EU3のもう一つの失敗はロシアがしょっちゅう建国に失敗し、東方がメチャクチャになって終わること。
6.スウェーデン ‐ スウェーデンの侵略がヨーロッパ北東地方の国境を形作りました。
7.ポルトガル ‐ 史実において、そして私たちの新しい交易システムの下でも、ゲーム最初の2世紀における彼らの影響はヨーロッパを永遠に変えてしまいます。
8.オーストリア ‐ ヨーロッパの半分に影響力を持つ中央ヨーロッパのプレイヤー。

Tier 2



Some comments here.. Netherlands didn't make the cut for the top 8, as they don't exist at the start. While we would like to see them in a fair amount of games, they are not a guarantee to happen. Poland and Denmark, while important countries from the start and have a rich history, we chose Russia and Sweden ahead of them in that area, as Russia and Sweden were the winners historically.


Tier 3

7.The Hansa


All of these are interesting countries to play.. While Eu2 at most had 2-3 events for these countries, we aim for far more, to bring them closer to what tier 1 and tier 2 countries could expect.
