Europa Universalis IV: Development Diary 23: Tell me sweet little lies...

Welcome to another Europa Universalis IV development diary – Number 23 in fact. We have already done three more development diaries than we’d done for Europa Universalis III, and we still have about 30 more possible diaries to write.* There is still a lot to talk about when it comes to...

Europa Universalis IV: Development Diary 22: A.E.I.O.U

Welcome to the 22nd development diary for Europa Universalis IV. The focus of this development diary is about the most glorious of nations, the Archduchy of Austria. This is the nation I've played the most in competetive multiplayer in EU2, EU3 and EU4, and they have a special place in my...

Europa Universalis IV Development Diary 21: Leaders & Mercenaries

Welcome to another development diary for Europa Universalis IV and today we focus on warfare. Yes, you knew this dev diary was coming, didn’t you? It’s really quite difficult to play the game without understanding how the armies work.

Warfare is one of the most important aspects of Europa...

Europa Universalis IV: The Special Christmas Bonus Development Diary

Most of the team is now off for the holidays, and the final remaining of us leaves today for up to two weeks of relaxations with friends and family.

The Europa Universalis IV team have worked very hard this year in making the foundations of a rather awesome game which has now reached the alpha...

Crusader Kings II: Sunset Invasion DLC - Dev Diary

As you know, we are quickly approaching the end of times, as a cycle of the Mayan calendar is about to end on December 21. Not to be outdone by the Mayans, we are doing our part to hasten the coming apocalypse by releasing a totally unhistorical DLC for Crusader Kings II called Sunset...

Europa Universalis IV – Development Diary 7 – And did those feet in ancient time....

“This England never did, nor never shall,
Lie at the proud foot of a conqueror”


Welcome to the 7th development diary for Europa Universalis IV,
where we talk about the dominant power by the end of the Europa Universalis time frame, the country formerly known as England.
England can be...

Europa Universalis IV – Development Diary 6 – Do you have any idea about it?

Welcome to another developer diary for EU4. This time its about country customization - our efforts to make each country truly unique.

We added National Ideas as a feature to the series in EU3. It was a great concept, because of how it added visible differentiation to countries, and we were...

Crusader Kings II: Legacy of Rome - Dev Diary 5: Events and Decisions

Legacy of Rome will be released next week, so this dev diary will be the last of this cycle. Doomdark is busy hammering away at the game, so this week the honor of writing it falls to me. As he said last time, we'll finish off with some of the unique decisions, events and mechanics we've...

Crusader Kings II: Legacy of Rome - Dev Diary 3: Combat Rebalance

Ears up folks, it's time for another Legacy of Rome and patch 1.07 dev diary! This time, I'll reveal what we've done to rebalance combat. All these things are actually in patch 1.07, so you'll get them whether you buy the DLC or not.

To give you some background, we were never entirely...

Europa Universalis IV – Development Diary 3 – Your envoys are awaiting your orders!

Welcome to another development diary about Europa Universalis IV (EU4)! This time we're talking about the envoys you have at your disposal.

Throughout the Europa Universalis series, envoys have been resources you could spend to take certain actions in the game. “Envoy” is a word we actually...

Crusader Kings II: Legacy of Rome - Dev Diary 2: Liege Levies and Retinues

Well, what do you know? It's Legacy of Rome dev diary day again! Today's topics are Liege Levies and Retinues.

In patch v1.07, you raise fewer, larger levies from your direct vassals (we call these "Liege Levies" for lack of a better term.) These levies are now handled separately from...

Legacy of Rome - Dev Diary 1

Hello again folks, it's time for another dev diary on Legacy of Rome! Today, I'll talk about the new Faction system as well as the changes we have made to Plots and Ambitions. Like I mentioned last Wednesday, Factions are part of patch 1.07 and will be available to everyone free of charge...

Crusader Kings II: Legacy of Rome - Dev Diary 0 - Clearing the Fog of War

It's Wednesday, and time to answer some questions about the upcoming DLC for Crusader Kings II; Legacy of Rome. The focus of this mini-expansion is going to be the Byzantine Empire and the Orthodox church. First off, in order to clear up any confusion from the original announcement, it's a...

Europa Universalis IV - Development Diary #0 - Our Vision

Hello everybody, and welcome to the first development diary for Europa Universalis IV. We've been working on this project for quite a long time, with the first design dicussions starting not long after Divine Wind was released. During last year we spent a lot of time working on the design...

The Sword of Islam - Dev Diary 3

Hello again folks! Stay a while, and listen. The highlights of today's third and last Sword of Islam developer diary are Muslim Casus Bellis, revised combat mechanics and cultural buildings. You know the drill by now; I'll talk about both some unique Sword of Islam features and some...

The Sword of Islam - Dev Diary 2

It's time for the second of three dev diaries on the new expansion for Crusader Kings II; the Sword of Islam! Those who watched yesterday's live stream already know a bit of what I'll talk about today. Just like last time, I'll talk about both some unique Sword of Islam...

The Sword of Islam - Dev Diary 1

Well, it's Friday and high time to spill the beans on the new expansion for Crusader Kings II; the Sword of Islam. Judging by the forum, playable Muslims is the most requested feature for CKII, and who are we to disagree? We always wanted to do it, provided we could do the...

Crusader Kings II - Post Mortem Dev Diary

The game is released, the reviews are in, and the response so far has been overwhelmingly positive. It's been a long road, and a few of you might be interested to know the dirty secrets of the development process here at Paradox... Also, what we have in store for you in the future. So don't get...

Crusader Kings II - Dev Diary 23 - Christmas Q&A

Well folks, we're coming up on the Holiday season and you already know almost everything about Crusader Kings II. So instead of a regular dev diary, let's run a little Q&A session. So, let's hear those questions and Santa Claus might just answer them. :)

Crusader Kings Dev Diary #21 - Usermodding

Hello, and welcome to another development diary about Crusader Kings II.

This time there are two subjects I want to talk in detail about, both related to something popular in this community, ie usermodding.

New file-system for Mods.

We have implemented a system in the game, where...

Crusader Kings II - Dev Diary 18 - The Council

Folks, prepare yourself for another monologue by yours truly!

Last time, I promised to talk about Crusader Pandas, but that would be silly, so I won't. Instead, I'll inform you about the workings of the Council. Just like in Crusader Kings, the Council consists of five characters who...

Crusader Kings II - Dev Diary 17 - The Message System

Hello again folks!

It's Thursday, and... well, you know the drill by now. The subject for today is the message system. Basically, we have been trying to find ways of making messages less intrusive. In a single player environment, a steady stream of pop-ups is not that bad, but when you run a...

Crusader Kings II - Dev Diary 16 - Technology

Greetings, fellow medievalists!

'Tis Thursday, and time for another entry in my ongoing chronicle of fabulousness. You have asked of technology, so today, being the just and kind ruler that I am, I shall speak of technological advancements.

The technology system is, in fact, quite similar...

Crusader Kings II - Dev Diary 15 - Buildings

It's time again, to fan the flames of speculation, chagrin and wonderment!

This week, I'll speak of buildings. In Crusader Kings, as you probably remember, you could build improvements in your counties; things like a library, a road network or money lenders. These would unlock as...

Crusader Kings II - Dev Diary 14 - Plots

Hello folks!

It's Thursday, and you all know what that means... pea soup, pancakes and warm Punsch! Also, a Crusader Kings II dev diary. Today's topic is Plots. Like in EU:Rome, characters can have a specific ambition in life. It can be innocuous things like...
