Mods and mod telemetry

Good evening, everyone. I’m Magne “Meneth” Skjæran, one of the programmers on CK2. In the past I’ve written dev diaries about modding, optimization, and quality of life improvements, and I'm writing this somewhat belated (due to technical issues) dev diary.

Today, I return to the topic of modding, and how we work to make life easier for modders. As a former modder, this is a topic I care quite a lot about.

If you’re anything like me, what you really want is statistics. How many people use mods, and which mods are the most popular. Luckily I come armed with exactly that.

As you might know, whenever you play CK2, the game collects some pieces of information about your setup. Things like what version of the game you’re playing, if you’re playing single player or multiplayer, what mods you’re using, and similar. This is all aggregated so that we can see overall trends and consider what areas might need some extra attention.

For mods, the main thing the telemetry provides is how many people use mods overall, and what mods these people use. My data will all be from users who played yesterday; anyone who during yesterday started the game with one or more mods is counted exactly once as a “mod user”, and counted once for each mod they used.

All told, 42% of everyone who played the game yesterday was using at least one mod. This could be anything from a small UI tweak, to a total conversion mod.
On average, anyone using a mod was using 4.24 mods. Once you start using mods, most people are not content with just one.
Further, here’s the 20 most popular mods, and how many percent of mod users (not overall users; multiply by 42% to get that number) that use them:

  • A Game of Thrones - 45.4%
  • Ruler Designer Unlocked - 30.2%
  • Your Personal Castle - 24.9%
  • Sketchy Cheat Menu - 18.1%
  • CK2 Russian Localisation - 13.7%
  • Historical Immersion Project - 11.3%
  • A Sensible New Family - 10.7%
  • CK2Plus - 10.6%
  • Bigger Interface - 9.0%
  • Purchase Claims - 8.8%
  • Patrum Scuta - 8.6%
  • Unique Buildings - 8.4%
  • Novus Graphicus - 8.3%
  • A Revolutionary Borders Mod - 8.0%
  • Shattered World - 7.5%
  • Korean SingleByte Patch - 7.2%
  • CK2Plus - India - 7.1%
  • Damascus Steel + Ancient Swords - 6.5%
  • Better Looking Garbs - 6.3%
  • Abdication - 6.2%
Combined, these 20 mods represent 60% of all mod usage. Since people who use mods on average use more than just one, it also adds up to more than 100% of mod users.

That AGoT comes first is unlikely to be a surprise to anyone; it has long been the most popular CK2 mod. Fun fact: AGoT is so popular, that its most popular start date is the 4th most popular overall startdate, after 769, 1066, and 867.

What is more interesting is that in the top 5 mods, two are “cheat” mods. Since they can’t be used in multiplayer unless everyone has them enabled, the idea of “cheating” doesn’t make all that much sense of course, and should instead be seen as achieving more of a sandbox experience than what the vanilla game provides.

Beyond that, there’s two localisation mods in the top 20; one for Russian language and one for Korean. The sheer amount of work that goes into translating an entire game is impressive, and it is great to see the modders’ work recognized to such an extent. Localisation modding is actually something we recently improved; in the 2.7 patch we moved custom localisation out of the “common” folder and into the “localisation” folder, meaning that it is now possible to use the custom localisation system without changing the checksum. This is especially important for languages with more complex grammar than English, such as the gender rules in French. The official French translation has for a while made use of custom localisation to change a number of words based on whether they’re referring to men or women, but doing similar in a mod would mean changing the checksum, making it impossible for the mod’s users to obtain achievements and play multiplayer with people not using the mod. This is something I know the Russian localisation mod has had problems with, and is a change I hope will lead to even better localisation mods.

There’s also a number of graphics and interface mods, plus several other mods that change the graphics or UI as a part of a larger package (E.G., the optional revamped interface in the Historical Immersion Project). People have done a lot of interesting things with the UI, but I know from experience it can often be somewhat tedious work. In the hopes of making it a bit less tedious, we’re making a console command that’s before only worked in the debug version of the game (which is not publicly available) available to everyone in a future patch (not 2.7.1). This console command is simply called “guibounds”, and what it does is that whenever you hover over a UI element, the area it covers is highlighted, and the name of the element, its size, and the file and line it is defined on is shown. This functionality is actually available in the release version of the game right now in a somewhat obscure fashion: if you try to open the console while on the main menu, it’ll be enabled. However, once you get into the campaign there’s no way to actually disable it since the console command isn’t available.
Below is an image showing what the guibounds functionality does:

There’s also a few large mods beyond AGoT in the top 20. CK2Plus even manages to take two spots on the list by including a mod that toggles the existence of India, while being pretty much tied with the Historical Immersion Project; some days HIP leads, other days CK2+ does.
The rest of the mods are smaller, adding small pieces of focused functionality.
Both types of mods we’re always trying to help by making the game more moddable. One changelog entry I think a lot of modders will find useful is this, which will be included in 2.8:
- Most effects and triggers that take a number can now take a variable name instead, and will grab the variable from the current scope. E.G., "wealth = test_variable"
This should allow mods to do far more interesting things with variables than is currently possible.

As a final note, modding is something we on the CK2 team take very seriously. Mods have the ability to add a lot of interesting alternative ways to play the game, and therefore helps keep the game fresh even for veteran users. In general, improvements to moddability also opens up new possibilities for our content designers, or can save them time by making their work simpler.
We’re therefore constantly considering how we can ensure new additions to the game are moddable, and we often go back and tweak existing functionality to open it further to modding.
We would love to hear your thoughts on what we could do better in this regard.

Will only return characters the player know is of the specified secret religion. Also added a "Has Secret Religion" filter that'll only show characters you know to have a secret religion - When you can rank up in your society you now get a separate alert that takes you to the Society screen, rather than being part of the "important decision" alert and taking you to the Intrigue screen - The ally order tooltip will now tell you when the AI is too busy with another war to help you - Fixed hidden character modifiers being visible on the title screen - No longer possible to give ally orders to other players, since nothing makes them obey them anyway - Fixed nation adjectives not getting properly localised in some cases - Council job selection now resets if your councilor dies or is replaced while you're assigning them a job - Fixed the notification when a settlement is finished saying "A Tribal has finished [...]" rather than "A Tribal holding has finished [...]" - The "claim" console command now gives feedback on whether or not it worked - The button that toggles all DLC in the launcher now toggles all mods if that's the currently selected tab - You no longer get the alerts for commander titles if you have "auto assign commanders" enabled ################### # User modding ################### - Fixed the game failing to find government unique title names at times. Now it'll never return the default name if a non-default one is defined. It now also tries without the tier string before it tries without the government string, so if you were to define "city_title" and "king_title", the former will be used - "add_law" can now take parameters: "cooldown" and "opinion_effect". "cooldown" simply works as a way to specify that there's no cooldown, like add_law_w_cooldown does. "opinion_effect" can be used to specify that the opinion effect of passing the law shouldn't be applied. E.G., the anger/happiness at succession law changes, or at tribal organization changes. Existing script still works as before. Example of new syntax: add_law = { law = true_cognatic_succession cooldown = no opinion_effect = no } - Messed up localisation is now less likely to crash the game - FROM in on_character_convert_religion and on_character_convert_culture is no longer a temp character, but instead the culture/religion itself. This only provides access to comparing to the culture/religion (or group). It should also still work to set cultures/religions and such. Please report any issues encountered with it. This change also means that it should now be possible to reference the previous characters outside "immediate" and similar without the game crashing - same_society_as trigger will no longer be true when both characters are not part of a society. - Added the command line argument -scriptlog to enable log triggers and effects without enabling script asserts. - Added artifact backgrounds (arti_bg.dds, arti_bg_glow.dds, arti_bg_small.dds, and arti_bg_glow_small.dds) to gfx/inventory/artifacts to make it easier for modders to make their own artifacts that follow the style of the vanilla artifacts - Added society icon backgrounds (society_symbol_bg_stone.dds and society_symbol_bg_wood.dds) to gfx/inventory/societies to make it easier for modders to make their own societies that follow the style of the vanilla societies - Added a better secret religion system, now based around a code attribute rather than traits. Characters can have up to one secret religion. If the character ends up as their secret religion, their secret religion is cleared. This can be set and accessed via script: - Added triggers "secret_religion", "true_religion", "secret_religion_group", and "true_religion_group". True religion being defined as your secret religion if you have one, otherwise your public religion - The religion triggers (religion, secret_religion, true_religion, and the group versions) can now optionally take a "target_type" determining which religion of the target they check against. E.G., religion = { target = ROOT target_type = secret } will check if the scoped character's public religion is the same as ROOT's private religion. The valid types are "public", "secret", and "true". The default is to use the same as the type being checked; religion default to public, secret_religion to secret, true_religion to true. A religion (group) name as the right-hand-side works for all the triggers - Effect set_secret_religion takes a religion or a scope. It optionally takes a target type (true/secret/public), but defaults to secret - Added trigger has_secret_religion which takes "yes" or "no" - Added set_secret_religion and clear_secret_religion effects - The "religion" and "set_secret_religion" effects optionally take a religion type (true/secret/public) to determine which to use when a scope is referenced. "religion" defaults to public, while "set_secret_religion" defaults to "secret" - Added "secret_religion" console command that sets a character's secret religion. Defaults to the player's character - Who can see a character's secret religion is defined in 00_religions.txt - Added a can_see_secret_religion trigger. Takes a scope, and checks if the character scope you're currently in can see the target character's secret religion - Societies can now have an associated religion, which is accessible from script in the same way as character or province religion, including on the right-hand-side of triggers and effects. This is scripted with for example "associated_religion = catholic". It has no effect beyond being accessible via script - Added a convert_to_secret_religion effect. Takes "yes" or a character scope. Sets your public religion to your secret religion, or the target character's secret religion if a scope is used - Added a on_character_convert_secret_religion on_action - Added SecretReligion and TrueReligion localisation promotions so that [This.SecretReligion.GetName] and similar work - Added a dynamic secret religious society system that significantly reduces the work involved in making a religious cult society - All religions except those specifically excluded get a secret religious society generated. The attributes of this society is defined by a template in 00_societies.txt - Most the sections in society definitions now provide the society itself as a scope (FROM) - Societies can now have an associated religion (defined with associated_religion = religiontag). This means that scopes can now be used where religions could be used, such as the right-hand-side of the "religion" trigger or effect. It also means that the "religion" trigger and similar can be used within a society scope - Added a secret_religious_cult scope, which will scope to the cult associated with the character's secret religion. Also works in religion and province scopes. This can also be used on the right-hand-side of effects and triggers - is_rank_full can now take a society scope rather than just a society name - Added a "secret_religion" history effect - Added an on_artifact_inheritance on_action - Scope: ROOT is the character, FROM is the artifact, FROMFROM is the old holder - Fixed bugs in artifact_owner and original_artifact_owner scope changes - Added tooltips for artifact_owner and original_artifact_owner scope changes - Added "owner" and "original_owner" as valid scope changes for artifacts - Added on_society_created and on_society_destroyed on_actions - Fixed scoping to saved society and artifact event targets not working - Added religion_scope, secret_religion_scope, true_religion_scope, and culture_scope as scopes. These scope to the religion/culture of the character/province/society (only religion for societies) currently scoped to. Can be saved as event targets - Added a save_conversion folder in "common" which handles converting obsolete objects in saves. Currently handles religions and societies - Added a clear_flags_with_prefix effect. Works in character, province, title, and artifact scopes - Fixed the society rank tooltip not having FROM defined. FROM is now the society grand master, as with other society tooltips - Fixed troops spawned to unlanded characters not getting any tech bonus. They now get the tech from the province they spawned in. If a "home" province is defined, they'll use that province's tech instead - Added "fallback_text" for custom loc. If none of the triggered texts return true, this will be used instead if defined. The fallback text cannot have a trigger, and only one can exist - Fixed the error log complaining if you use "set_mother = 0" - Added is_interested_in_any_society = <yes/no> trigger. It evaluates if you're currently showing interest in a society or not. - Society.GetName, Society.GetNameCap, and Society.GetCurrency now fall back to null_society and null_society_currency rather than just ending up blank - Fixed the "has_artifact" condition showing up blank - Fixed the game crashing in some cases after resigning and reloading, and hovering over a port that had a fleet in it when you resigned - Fixed reverse_religion not working in some cases. Only affected the 2.7.1 beta - Restored the behavior where "culture_group = something_that_doesnt_exist" always returns false. Only affected the 2.7.1 beta - Ensured "portrait_society = something_that_doesnt_exist" always returns false ################### # Database ################### - Barbarossa now has a magnificent red beard - Fortun Garcia is now One Eyed rather than Maimed - 953 new Wikipedia links - Fixed counts of Zollern - Fixed date of birth/death and mother for Otto III of Anhalt-Bernburg - Fixed date of death of Maria of Brabant - Fixed date of death of Otto IV - Fixed date of birth/death and parentage of Guy I of Ponthieu - Fixed parentage of Even "le Grand" de Léon - Fixed date of birth/death of Saint Judicael - Fixed date of marriage of Arnold II of Looz - Fixed various database issues in the Italian character file - Fixed a bug with dynasty ID of Dante - Fixed improper dynasty ID for Abu Man'a Khamis - Fixed dates of birth for a couple sons of Drogo of Champagne - Fixed date of birth of granddaughter of Charles Martel - Fixed bad spouse ID for Adalbert Adalberts - Fixed mother ID and removed bastard trait for Pepin the Short - Fixed date of birth of Theudebert I - Adjusted date of death of Godfrey of Hainault so he isn't 110 - Adjusted date of birth of Hamon of Leon to avoid false twin issue with brother - Adjusted date of death of Riotham so son's date of birth makes sense - Adjusted date of birth of Avice Cerneu to be consistent with father's date of death - Adjusted date of birth of Azenor la Marck to avoid false twin issue with sister - Adjusted date of birth of Budic of Nantes so his son isn't born when he's 8 - Adjusted date of birth of Evenus of Brittany to avoid false twin issue with brother - Adjusted date of birth of Louis IV of Looz so his father isn't 11 when he's born - Adjusted date of marriage of Charles Martel and Rotrude of Hesbaye - Added Vitiges of Ostrogoths - Added Ostrogoths to title history of k_italy - Added parentage to Alberada of Buonalbergo - Added missing marriage between Alan IV and Ermengarde of Anjou - Added Vandal kings to k_africa title history - Added Visigoths to Duchy of Toulouse title history - Added missing marriage between Maria of Brabant and Otto IV - Added missing marriage between Alaric II and Theodigotha - Added missing marriages of Gruoch of Scotland - Added missing marriage between Theophylact I and Theodora - Added missing rulers for Corsica and Sardinia titles - Added the House of Cinarca, who ruled southern Corsica, and missing Italian relatives - Added complete Dynastic Family Trees for the Giudicati of Sardinia, and missing Italian relatives - Added some unlanded Grant and MacCleod characters - Added early Baduspanid characters - Added early Ziyarid characters - Added more title history to Dailam, Mazandaran, and Gurgan - Added homosexual trait to Hadrian - Added a missing twin trait to some fictional Pecheneg characters - Added spouses and more children for al-Mahdi - Added Dabuyid dynasty - Added a weak claim to Scotland for Robert the Bruce - Deleted unnecessary remove_spouse declaration for Conan IV - Removed redundant marriage declaration for Avice Cerneu - Removed invalid father definition for Wigbert Immedinger - Replaced 867 holder of Faroes with a semi-historical character - Modified Hadrian and Julian to have beards - Modified Baduspanid and Ziyarid characters in 1066 to have sympathy for Zoroastrianism - Modified the Merovingian, Wuffing, and Caimbeul coats of arms - Modified Sassanid, Baduspanid, and Ziyarid coats of arms ################### # Bugfixes ################### - Added some flavor text for sacrificing the Aztec religious head during a blot - Fixed the game sometimes pausing without allowing you to ever unpause in the tutorial due to an event triggering - Fixed it in some cases being possible for priests of religions where priests are not allowed to marry to marry or betroth someone - Fixed the AI in some cases switching capital for no apparent reason - Fixed changing primary title allowing you to pass another demesne law - Fixed artifacts sometimes starting off inactive even when the trigger is met - Fixed log message about "Malformed token: achievement" for ironman saves - Fixed it being possible to pass laws by ensuring you have no councillors whatsoever.

“...playing is winning, and there’s something quite satisfying about leading your house to power and glory through whatever means you can, for as long as you can.”
9,5/10 – Strategy Informer

“In short, Crusader Kings II is a majestic feudal sandbox, the greatest generator of hilarious medieval soap opera ever created and Paradox Interactive’s best title to date.”
90/100 – IncGamers

“It's perfectly possible to have made a few too many enemies, anger the Pope and find most of Europe out for your blood. That's really what makes the game so damn fun.”
9/10 – Destructoid

About This Game

The Dark Ages might be drawing to a close, but Europe is still in turmoil. Petty lords vie against beleaguered kings who struggle to assert control over their fragmented realms. The Pope calls for a Crusade to protect the Christians in the Holy Land even as he refuses to relinquish control over the investiture of bishops - and their riches. Now is the time for greatness. Expand your demesne and secure the future of your dynasty. Fill your coffers, appoint vassals, root out traitors and heretics, introduce laws and interact with hundreds of nobles, each with their own agenda.
A good lord will always need friends to support him. But beware, as loyal vassals can quickly turn to bitter rivals, and some might not be as reliable as they seem... Stand ready, and increase your prestige until the world whispers your name in awe. Do you have what it takes to become a Crusader King?
Crusader Kings II explores one of the defining periods in world history in an experience crafted by the masters of Grand Strategy. Medieval Europe is brought to life in this epic game of knights, schemes, and thrones...
