Today is thursday, the day of the God of Thunder, so what is a more appropriate way to celebrate than with a development diary for Europa Univeralis IV. We’ve talked about development and politics the last few weeks, so now its time to talk a bit more about warfare again, before going back to more peacetime-related activities.

All of this mentioned in this development diary will be in the free update accompanying the next expansion.

Fortress Rework
Connecting a bit to the previous reveal of our change to how building works, we have overhauled the fortress system.

There are now four different forts, one available each century, providing 1, 3, 5 and 7 fort-levels each. A newer fort makes the previous obsolete, so you only have 1 fort in each province. Each fortress also provides 5000 garrison per fort level, so besieging a fortress now requires a large investment.

Forts now also require maintenance to be paid each month, which currently costs about 1.5 ducats for a level 1 fort per month in 1444. Luckily, you can mothball a fortress which makes it drop to just 10 men defending it, and won’t cost you anything in upkeep.

Garrison growth for a fort is also a fair amount slower than before, so after you have taken a fort, you may want to stick around to protect it for a bit.

What is most important to know though, is that forts now have a Zone of Control. First of all, they will automatically take control of any adjacent province that does not have any forts that is adjacent and hostile to them. If two fortress compete over the same province, then the one with highest fort-level wins and in case of a tie, control goes to the owner of the province. Secondly, you can not walk past a fortress and its zone of control, as you have to siege down the blocking fort first.

Each capital have a free fort-level, but that fort will not have any ZoC, as most minor nations can not afford a major fortress.

Looting
As we promised, we have now completely revised how looting works. Now there is a “pile” of possible loot in a province, which is directly tied to have developed the province is.

At the end of each month, all hostile units in a province attempt to loot, and the amount they loot depend on how many regiments you have there, and what types they are, where cavalry is by far the best. Some ideas and governments increase the amount you loot each month, where for example Steppe Hordes gains a nice boost.

A province starts recovering from being looted when 6 months have passed since last loot, and it takes up to a year until it has fully recovered.

Of course, the penalty on a province from being looted is still there until it has fully recovered, but it is scaled on how much have been looted.

Committed Armies
One of the major complaints we have had on the combat in Eu4, has been the fact that you can fully abort your movement whenever you liked. This have been changed, and now you can’t abort your movement if you have already moved 50% of the way. After all, its just common sense that a unit that have already moved halfway between the centers of two provinces is already in the second one.

Force Limits
We felt that the calculations of forcelimits where far too hidden from the player, Players saw stuff like “+25.87 from Provinces”, which based based on projections of base-tax amongst other things, and sometimes those dropped for no obvious reasons.

Now you will be able to see in each province how much it provides to your forcelimits, and we have cleaned up the logic.

Each level of development gives 0.1 land and naval forcelimit.
Overseas will provide -2 land and -2 naval forcelimit
Inland provinces will not provide any naval forcelimit.
However, a province will never be able to provide negative forcelimits.

A nation also have a base value of +3 land and +2 naval force limit, and there are some other ways to get direct forcelimit increased, that are not just percentage increases.

Next week, we'll be back and talk more about The Devout.
 
Also, does this indicate the removal of the World Conquest achievement? It's already difficult enough, but it would have to be impossible if you can't carpet siege. Because if I understand this correctly, carpet sieges are now a thing of history if you cannot pass a fort without defeating a fort. Going to stink beating back hordes of French mercenaries as you try to siege their border provinces. lol
There are going to be gaps to move through unless a nation goes crazy building forts. And with the number of buildings depending on Development and terrain, you're probably not going to see forts everywhere.

Ah. I see! So forts simply won't exist in most every province like they do now. They will be strategically placed. Interesting... I think I am actually starting to love this idea. This actually does make more sense for larger nations as in real life, you armies didn't just sack fort after fort. Pick and choose what causes their opponent to crumble.. Awesome! Though I am concerned the HRE will be close to 100% forts due to all the minor nations having only one or two provinces...

Seems very promising, now there's actually more of a reason to have a string of high level forts at one's border since the enemy litterally cannot walk past them.

Have you considered tying the "blocking-function" of forts to leader maneuver-skills, in such a way that a leader with a high enough maneuver-skill (maybe more than 1 maneuver pr. fort level) can sneak an army past a fort and loot the interior. It would be a nice boost to maneuver.

EDIT: Removed quote from OP, since the quoted passage has been edited

So what does zone of control mean? If I take a like level 3 fort, do all adjacent provinces with lesser fort levels automatically get occupied by me?

Also, what is going on with the map? Independent Nassau tag? New tag in Memmingen? More provinces in Bavaria? Burgundian vassal swarm?

Also one important question about ZOC and Fortress. If I enter ZOC of fortress (for example I'm fighting enemy who is not fully revealed) am I able to walk around in that ZOC? Where can I leave that ZOC? And what if there is chain of Fortress Province - Adjacent ZOC Province - Another Fortress Province. Am I able to move from that ZOC? And what If I have

Fortress Province - Adjacent ZOC Province - Adjacent ZOC Province to Another Fortress Province - Another Fortress Province. Can I go from First Adjacent ZOC Province to another or not?

If you take control of the fort you also get thr surrounding provinces, so that will speed it up a litttle

If I understand correctly, carpet sieging will be more costly, but not impossible. You do not have to capture the fort, you have to start a siege (probably an amount of your solders at least equal to the garnison size have to stay in the province to let you start the siege and block the fort).

I am salivating at the idea of playing as Norway and after capturing all of Denmark, putting forts at Holstein, Schleswig, Fyn, Skjaelland, and Skåne. In addition, Aland, Stockholm, Fyn, Osterbotten, and Finland. Not so much because I don't already control all the navy, but that would prevent backdoor invasions of the mainland when I am not paying attention. Though that many forts may be expensive, but it would be nice to be able to focus elsewhere without the random notification "Dalaskogen has fallen" only to see a six regiment army had taken it. lol

No, you can't go further into enemy territory.

If you enter the ZoC of a fort, you can only go back to previous province OR on to the fort.

This kind of reminds me of Rise of Nations in their old "zone of control" system. I guess a lot of this really depends on how many forts a nation can really afford. Or rather, what percentage of provinces can be forts without going broke. But my concern is still the HRE since many nations there are one or two provinces. Since capitals are automatically forts, coalition wars or wars against the emperor will be even longer and even costlier.

Ouch. That would answer my concern about fighting the HRE emperor as say Denmark. Sounds like there will be some super fierce battles over Lübeck, Lauenberg, Holstein, etc.
 
Although I'm unsure about some of the changes, they seem revolutionary gameplay wise, I am hyped to high heavens! I like the direction this is going, and I mean that. I was quite vocal about my disapproval of El Dorado, I hope to be just as vocal, but also approving of these new features. What will the DLC / patch be called?
 
Sweet! Looking forward to this changes, gj Paradox.

So I could now somewhere in narrow area in mountain range build a nice fort or two, place an army there and voila, you shall not pass! : - ) Increased garrison is also great, no more 2000 people taking Paris. Also it would be nice if we had some special siege events like in CK2 or a bit harsher attrition in fortress provinces, so it would take a bit more than to place 5k men and forget about siege.

I don't think conquest will be slow, if you take the forts other land will fall automatically, speeding the things nicely. For example in that screenshot aboce, conquer Paris and you get as a bonus 5 surrounding provinces, providing that they don't have forts.

Loot change is also nice - there's something rewarding in that concept. Wonder if they could implement "looting mode" on armies like in CK2 so we can loot provinces without war declaration? Its not a Viking age, but maybe for Hordes and some other looters...
 
so if I've read this right:

Forts are now deathstars and entering their tractor beams will not let you escape until you siege them.

Non fort and non fort-adjacent provinces are now insta-sieged?

Forts now siege down all adjacent opposing provinces of lower fort value?
 
Forts now siege down all opposing provinces of lower fort value?

This would lead to a question. Say you are France and have a level 7 fort on the border, a level 5 a couple provinces in, a level 3 a bit further in, then a level 1 a bit further in. They sack your level 7. Does this mean half your nation falls with it as a domino effect of stronger fort taking weaker fort?

With individual forts growing in importance to rival that of a small army, any chance they could get army-like icons? A separate map mode seems insufficient given that we will want other information at the same time.
