EU4 Development Diary - 11th February 2016

Hello and Welcome to another development diary for Europa Universalis IV. This time we take a look at a concept that neither we nor you have not been entirely happy with in any previous Paradox game: Espionage.

In the next major patch, we have completely reworked how espionage works. No longer is every spy action done by just sending a diplomat that will perform the action for as long as it is there, but now there is a concept of spy networks.

You now send a diplomat on a mission to a country to build up a spy network. The network can reach up to 100% power, and that power can be used to execute spy actions, such as sow discontent, fabricate claims, etc.

Spy Offense has been renamed to Spy Network Construction, and determines how quickly you build spy networks in another nation.

Spy Defence has been renamed to “Foreign Spy Detection”, and now determine the chance of detecting hostile network buildups and disrupting it. A disrupted network will lose some of its power, and also make it impossible for you continue improving it for a time period.

Performing an action is instant, and as long as you have the power, success is automatic. However, networks that are not actively built will slowly decay.

You can also target other nations networks with counterespionage, to actively reduce their capabilities of their network.

There are three passive benefits to having a strong spy network in another nation. First of all, if you have the Cossacks expansion and picked the Espionage Ideas, you have access to Study Technology, which is no longer a source of power, but instead a possibility to reduce technology costs by up 30% from having networks in nations ahead of you (the size of the discount depends on how far ahead they are in each tech). Secondly, the new expansion grants up to 20% higher siege ability against nations where you have a spy network. Finally, the new expansion gives you up to 10% less AE in that country.

Of course, all of those scale with the power of the spy network.


Espionage now contains the following actions.

Fabricate Claim: Gives you a claim on an eligible province for a low cost.
Justify Trade Conflict: Gives you a trade conflict CB if conditions are applicable for a low cost.
Support Rebels: Selected rebel faction gets +10% chance to progress towards revolt each month for 5 years for a very high cost. It will also cost a fair amount of cash to support ythe troops.


The following requires the Espionage Ideagroup.

Sow Discontent, applies +3 unrest and reduces legitimacy, republican tradition, devotion or unity for 5 years for a high cost
Infiltrate Administration: Lifts Fog of War over the target country for 5 years for a medium cost.
Sabotage Reputation: -3 diplomatic reputation for 5 years for a medium cost.
Agitate for Liberty: Selected subject has +25 liberty desire that lasts 5 years for a high cost.


There is also four new actions enabled by the new expansion, two of those we’ll tell you about here, two others are for future development diaries.

Sabotage Recruitment: Gives 20% less manpower and Sailor recovery speed for 5 years for a medium cost.
Slander Merchant: Reduces Global Trade Power by 33% for 5 years for a high cost.

Of course actions that require previously expansions will still require those expansions.

Next week we’ll be back with a look at Africa.

Given the fact that France established a colony after a war with the local Merina kingdom , there should at least be something before "madagascar"... if not the Merina Kingdom, itself credited to be created in the first decades of 1500, at least a tribal state of the Imerina

And more provinces for Madagascar, hopefully,

So we still have to dedicate a diplomat on this action?
Only on the base action of building the network it would seem.

Are espionage ideas required for those?
Yes.

Also, just to clarify, "cost" refers to paying with some of your spy network's power?
Yes.

Can those actions be stacked, if you are targeted by more than 1 country?
Can every little OPM reduce the manpower recovery speed of an 1000+ development empire?
I would assume it would be in the same vain as "Agitate for Liberty" [one effect no mater how many apply it].

This is pretty underwhelming. The underlying way that espionage works is still more or less the same in that you still rely on sending diplomats for x period of time to have an effect, The only difference now is that you can have multiple actions in a short period of time after a longer wait.

Ultimately for espionage to become something worth investing in you need to have spies, diplomats already have plenty to do. I also agree that the espionage idea group should be about making espionage more effective not simply allowing you to conduct espionage.

Honestly unless the results of espionage are comparable to the damage one can do by say investing in a larger army then the whole concept will continue to be consigned to the dustbin.

I'm worried about random OPMs picking Espionage and messing with huge empires. We already have this issue with agitate for liberty, and this rework will likely make it worse.

Here's my suggestion:

Some espionage actions (those which have a nation-wide effect) should have a gold cost which scales with the size of the target. Maybe increase the effects of those actions a bit in order to balance it out. This would have the following benefits:
  • It would make Espionage interesting for large nations (instead of it being a small country only thing).
  • It would insulate big nations from annoying random OPM espionage which adds nothing to the game.
  • It would make gold more valuable, buffing income NIs (which are really weak compared to military NIs right now, specially in multiplayer).

It seems to me so long as the special Espionage idea activities have any significant cost to use (in cash), they will not be used. They already cost an idea group. How could they possibly be worth paying even more than that?

it's a nice touch that the Rybinsk Reservoir is gone from the map (as it was only filled in the 1940's). any chance the same thing happens to the Manicouagan Reservoir in Quebec? :)

Can we talk about how obnoxious it is to have no way to stop Agitate for Liberty or support independence? How about a CB that forces them to revoke it and/or punishes for spy actions?

or add a peace option to destroy all spy network power they build and stop them from building new network during truce

Since there are relatively few ways of increasing spy defense, increasing the effectiveness of espionage TOO much will make taking the Espionage group mandatory, which is just as bad as its current nigh-useless state. It's not like improving your military which, while mandatory, at least allows you have the choice of 4-5 idea groups to bolster your might (as well as spending MP on generals, building hiring lots of mercenaries, etc)

They mention active counterespionage in DD, not sure how it work, but i agree we should have more way to increase spy defense.

Could you discuss how you will be ensuring that being ganged up on by the AI (or, perhaps worse, other players in MP) won't result in the game losing its fun?

As an example, the seduction focus in CK2 wasn't a bad idea, but early on in it often have annoying results. For example, a female emperor of a large realm might be bombarded with seduction requests at a rate of several per month.

If a big chunk of the HRE were to get pissed off at you (for example, because you took a province from the empire), does your nation get debuffed in every way as dozens of princes all focus their espionage on you? If so, will that negatively impact player enjoyment?
 
Good and welcome change, although I would like to say that I agree with two other points mentioned in this thread, which is to separate espionage from diplomats and make it so that actions are not tied to the idea-group/tech, but rather free to use and more efficient/less costly/etc with the idea group.
 
Please assure me that the spy network building speed scales with the relative size of the sending and the recieving countries.
I.e.: As a Poland I don't want to keep opressing Lithuania, because Frankfurt decides that Lithuania shall be free and can send that action like every 6 years.

Thanks!

It will most likely work as it does now.
Meaning, if each one of them performs a different action, then yes. If the action is the same then only one effect will be applied.

Yes.


Not answered, but most likely.

So I guess once you get a certain size you get a perma-reduction of manpower replenishment, because once you are big enough SOME ONE will ALWAYS be trying to do that to you.

Beside the usuall espionage stuff I hope we could effect economy aswell. Rasing advisor cost or colonisation cost.
Colonization cost? Sure...maybe. Advisor cost? Never! Small countries already often can't afford any advisors. You really wanna make it worse?
