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.
 
I didnt noticed. Could you point them out?
They're in Bavaria. Memmingen got shorter and now owned by a new tag. Niederbayern got split into Landshut, Straubing, and another province (Regensburg?). Plus there's also Ingolstadt taking up part of what used to be Memmingen and Niederbayern.

Also a new tag in Nassau.

All good news and adds to the strategic element of warfare!
 
Dear god what implications does this have for navals invasions. Johan mentioned that provinces without forts and outside of a forts ZOC will just instantly fall now, France and Spain can't afford to make freaking sea walls how easy will it be to launch a naval invasion from behind and half their territory

Well that just not true, France and Spain *can* afford to protect their coast, but other weak nations will have more problem with that - which is as it should be. Add to that that pretty much noone dares to attack France and Spain.
edit: Its logical that country is supposed to protect their most valuable seaports

Thanks. Now I wonder if its the final setup or Europa is gonna get more provinces? Like its in Veritas et Fortitudo Mod.

If you could theoretically take half their territory with a single doomstack, then more would be willing to do it as you'd kill their finances instantly. A lot of this just depends on how many provinces per fort there are on average. Also how big the fort's zone of control is. If a zone of control is only one province and a mostly formed France can only have five, then they could be exploited... If a mostly formed France can have say 20, then there will be so much zone of control that any naval invasion would have to be legitimate.
 
One question though: how will forts and other buildings carry over into later bookmarks, i.e., when starting at higher tech levels (say, when starting in e.g. 1650)?

Will they be considered automatically built as currently (1.11.4 and before), and will that work well with Development levels, or will there be another approach when determining which provinces get which buildings when sharing in later bookmarks, at higher starting tech levels?

EDIT: Because if the former, then all provinces will have get a fort, at higher level the later you start, which may not be optimal in the very late bookmarks.

(Sorry if this has been asked before somewhere else.)

Your concern is legit, its up to PI to code AI to build forts in important provinces, they shouldn't let Spain to have only 2 forts so it falls that easily. I don't think this will be the case, for example check Portugal in some 16xx-17xx game, they have level 4 forts everywhere in Iberia. Now i also hope that they won't have these high level forts everywhere or it will be very tedious..

If the player is able to take high level forts in 4 major centres of the country than AI should surrender, I don't want to carpet siege other 20 provinces and isolated islands like i have to now.
 
Oh wow, thats a different game! I love those changes! It looks like forts are really expensive though if ottomans are at deficit in 1444 due to forts.
 
So what does this mean for the Burgundian Inheritance?

Does this not mean you can get half warscore almost instantly if all a country doesn't have a ZoC all over their border?

But of course most important is the change to Ulm's borders (and the rest of the area, nice to see more princes with every patch).

How will Zones of Control interact with Shattered Retreats? Will a shattered army be trapped in hostile territory if the defender recaptures the fort that the attacker captured to get in?

It also depends highly on how large the zone of control is. I wonder if they will do it on province number or mileage circumference. For example, should a fort in Northern Norway, Northern Sweden, or Muscovy control two adjacent provinces if the same level of fort in Eastern France does?

Maybe sieging down forts would add alot to WS. Also it should be considered with the forts that 40 WS cap gained/loosed from battles needs to increase to motivate ai to be more inclined to make peace if lost all her war capacity.

This entire post is giving me the mental image of you going to war and your adviser saying "we can't move our armies sir, our enemies have constructed a fort in the nearby mountains!" Then you go outside and look at a bunch of french men sitting on their fort taunting you.

There was a great suggestion in the suggestion forum a few months ago I got inspired by to design some more flavor and fun for theocracies in. I doubt we'll have an entire expansion dedicated to Theocracies, but its just common sense to add it in to another expansion soon.

One of the criticism we’ve had regarding EU4, have been that the game has always premiered conquest, and if you didn’t expand, you fell behind. In the next major update, you’ll be able to make an empire that is more focused on tall than on wide. After all, it is just common sense of us to listen to what the community is requesting.

Common Sense (also a book... Which thinking about it may actually be more appropriate)

Level 7 fort = 35,000 garrison. That is going to be a lot of attrition on the besieging army... if they maintain the option to sally forth, that is going to be a helluva stack added to the battle. Especially if they were to program the AI to use that option. Would make taking human controlled level 5 or 7 forts nearly impossible.

Why?

provinces without a fort or adjacent to a fort will just fall to anyone passing through.

How large is the ZoC for forts?

Good question. I guess it varies for different fort level, level 1 getting no ZoC, level 2 getting 1 or provinces' ZoC, etc.

And interesting also to hear how forts get allocated at later start dates (when mil tech is higher at start), i.e., will there be e.g. level 3 forts in ALL provinces when starting in year 1700?!?
