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 concepts, and late in 2011, the core team was assembled, and actual development started.

Earlier this month, we announced the game at Gamescom, and showed a minor subset of the features for the game. Today we start a series of weekly development diaries where we'll go into detail about the game. Our goal is to release an entry each friday, with breaks for holidays.

The subject of todays diary is 'Why do Europa Universalis IV and what is our goal with the game?'.

Why are we working on a sequel to Europa Universalis?

Well, first of all, the team we are all major fans of this series, with me personally being the core guy behind the original game, back in the late 90's, and the others being involved for quite a lot of time on it. We are a group who love playing Europa Universalis (EU), both in singleplayer and in multiplayer together, so you could definitely say it is the favorite series for the people working on Europa Universalis IV.

Originally EU1 started development in 1997, EU2 in 2001, EU3 started in 2005, so we were overdue a new take on the genre. During those years we've accumulated quite a lot of ideas, and discarded far more. We've come to understand what Europa Universalis is about for a lot of people, and what it means for ourselves.

One important thing though, is that while we had lots of cool and interesting ideas for EU, we simply couldn't just add them all in, as the game would become an unwieldly mass. EU has a complexity level we do not want to dramatically increase and while improving the interface can reduce it a fair bit, it is a very fine balance when it comes to designing a game.

So we took a step back and looked at what Europa Universalis was and what we wanted to do, and since its a new game, we had quite a large amount of flexibility. We could rewrite entire systems from scratch, and do some paradigm shifts. One such example is the complete removal of the old trade system with centers of trade, which was replaced with a new trade system with dynamic flow of trade. This flexibility has been a great benefit when it comes to designing the game.


So then, what is our goal with Europa Universalis IV?

In all our games we aim to have believable mechanics. When playing a Grand Strategy game it should be about immersion and suspension of disbelief. You should feel like you are playing a country in the time period. This is something all our EU games have managed to achieve, and it is very important that EU4 will have that same feeling.

The game should, as we mentioned earlier, not increase its complexity levels dramatically. We are happy with the level of complexity the Eu-series has, and want to keep it at this level.

One of the most important aspects of EU4 is to make an interface that is both easier to get into, and less hassle for an expert user. This a fine line to balance, and we are rather happy with the interfaces we have done so far for EU4.

We also want to make sure that players feel that this is a new game, that this is worth paying money for, and this comes from new mechanics and better interfaces. With detailed dev-diaries every week until release, we are rather confident that you'll all be excited about it when its finally ready.

So, now we've just talked about history and visions, I'll try to clarify a confusion about sandbox, historical events and plausibility. Europa Universalis have always been about historically plausible outcomes, as I mentioned over six years ago , and EU4 is no different in that regard. No determenism or full sandbox will ever be in the EU series. In EU3 we scrapped historical events and added lots and lots of system and mechanics to create more plausible gameplay. While we are continuing on that concept and keep making more plausible mechanics, we are in EU4 doing something new...

We'e adding in Dynamic Historical Events. We'll have more of those than we had historical in EU2, and together with a fair amount of other planned features, this is creating an even more immersive type of gameplay, where countries feel far more unique than they did in any previous game in the series. A 'dynamic historical event', or DHE for short, is an event that has some rather rigid triggers that they feel plausible to happen with, ie, no Spanish Bankruptcy just because its a certain date, but events that tie into mechanics rather heavily.

The example I want to talk about is War of the Roses for England. At any point of time, before 1500, if England lacks an heir, then the chain for War of the Roses can start, which creates a lot of interesting situations for the player, as well as giving unique historical immersion.

Next week we'll talk more about the map, so enjoy for now!

I can see that getting out of hand. Remember those strange screenshots threads where there was coup on coup with a dozen pretenders claiming the throne in a row.

Be sure that it doesn't expand into a giant spamming of rebels and pretenders. :)
 
Not so thrilled, to be honest - the risk of having a "two-speed game", were you can play the Big Eight or Everything Else, seems to be quite big. Which, seeing as a lot of people stop playing majors after a while, could have troubling proportions. Of course, this wealth of conditionals and may-be is there for a reason. Will keep an eye on this.

where did we say only "big 8" would get lots of events?

I said 8 countries are important for us... their performance is what drives the eu experience.
 
Sounds about right as a distribution percentage.

This is Europa Universalis.

This is the kind of reply I like: from a direct trusted source, specific, leaving no room for useless debate :).
 
Question: Will there be more generic version of DHEs for other countries. For example, you have a set of conditions for the Spanish bankruptcy, but what if another country, say England, found themselves in a similar situation? Will England also get a bankruptcy event of some kind, though perhaps a bit more generic and less unique then the Spanish version?

Likewise, you have the War of the Roses, but will there be more generic succession wars as well? Not as flavourful, but still an ingame effect.

There was something like this in EU3. There was the generic revolution event which would turn your country into a revolutionary republic and the revolution target, and there was also a special flavour version of it which was specific to France and caused a tag change to Rev. France.

Yes, this is sort of what I'm thinking. Though some very specific events might have no generic versions.
 
B-but I wouldn't have objected to this :(

I own quite a few Paradox games, but have always found the EU series the most approachable. So, I'm glad that isn't changing.
 
How many provinces does EU4 have? Will it have more than EU3 or around the same? Will future EU games (many years from now) offer way more provinces (more than CK2 and V2 but less than HoI3)?

From the perspective of mods involving alternate starting conditions, more provinces = more work since Paradox changed to controlling this in individual history files per province. Wasn't so bad when it was controlled from a single scenario file, but IIRC that constrained you in normal play to starting dates that had scenario files. Anyway, due to this consideration I would not want to see an increase in provinces unless there was some particularly good improvement it depended on.
 
Country specific, all the texts are rather country specific, and they are unique for that country.

Will there be unique events for Ulm?

The main thing is that civil wars and coups should be realistic and not whack-a-mole. CKII really works for this because when vassals rebel they do so in a co-ordinated fashion and have a tagged AI controlling them, rather than being simply a spamming of generic rebels.
 
All Eu3 events are still in, and lots more coming. (of course, some random ones affecting mechanics not present anymore may have been cut.)

Does that include Chinese, Japanese and Korean events from DW?


Does that mean no country-specific (DHE) reformation related stuff (e.g. religious wars if France/HRE)?

To be honest I was hoping for a more "everyone can get standard event chain but some countries get an exttended event chain" type of approach with the new historical focus. I guess that would be too complex.

Pity you didn't add War of the Roses in 5.2. The Lancaster and York tags are just taking up space.
