CK2: Dev Diary #117 - Historical Wonders

Hello, builders, architects and peasants.


Today we will be telling you about the Historical Great Works that already exist in game. Of course there are so many Great Works that it would have been hard to fit them all in so we have chosen just a select few.


We also decided not to place a Great Work in Constantinople. The walls are already represented in game, and this will give the player a chance to build their own Great Work there. Also adding historical Great Works is rather easy via modding so you can set up the exact type of Great Work you want!


So without further ado I present the historical Great Works present at the 769 game start:

Pyramids of Khufu

Great Works in EU4
The thousands of ducats that the rulers invest in the foundations of the Great Works are investments that will have effects for ages. To make sure this characterizes your realm even more, we’ve made sure to transfer these feats when we’re converting save games from CK2 to EU4.


The rule is that every Great Work that has completed its final stage will be represented by a permanent province modifier in a converted EU4 game. By default we also ignore any historical Great Works that were present at the start of the campaign of CK2 but that rule is easily changed by modifying a value in the defines file before converting.


Different types of province modifier will apply depending on the type of Great Work it originated from. The following list will define the effects of the fully completed Great Works in converted EU4 games:

Papal Influence +1

Grand Mosque
Local Tax Modifier +100%

That's all for today! But if you want to check out what this looks like in-game, please tune into our first ever 3.1 Great Works stream today (Friday the 22nd) at 14:00CET on twitch.tv/paradoxinteractive where we’ll be playing on the hottest of code.

If you can’t catch the livestream, we’ll be uploading it to our YouTube channel soon, and it is also always available in the Twitch VOD archive.

Why no COLOSSEUM? No Haghia Sophia? No Cabaa? No Jerusalem Wall of tears?
Well, i think that wall of tears should appear via decision for jewish king+ as I tier 3td temple if nothing else is build (and if is just should override previous wonder)
 
I think having the Temple Mount as the great work for Jerusalem would make a lot of sense. Perhaps a bit awkward to code, though, since you have competing monuments there: the Western Wall (as mentioned directly above), the Dome of the Rock / Al Aqsa Mosque, and any Third Temple that someone might wish to build, giving competing bonuses to different religions and all. Combining them into one "Temple Mount" work might be the best, if clunky, approach, I think, perhaps with demolishable upgrades suggesting which religious work is the dominant feature.

Wait, is there a cap on the global additive modifiers such as these and others?
I can imagine that if you build several of those, it might become quite broken.
 
Loading a previous save would leave the world devoid of historical Great Works as these are created when we resolve history at the beginning of the game.
Great Works can be turned off in the game rules. It can also be set to allow only the historical ones and if you want to be really strict you can also set it to a restrictive mode where the great Works exist but neither you nor the AI can change them in any way.
Does this mean that if I load a previous save that was started before the update that I'll be able to build great wonders but there won't be any historic ones?
 
@MonzUn Can provinces have more than one Great Wonder?

For example, in Rome there's also the Colosseum, the ruins of the library of Alexandria etc?

Also will Hellenics have any special wonders they can build aswell? (A special mausoleum that allows you to search for Alexanders body to entomb it perhaps, could work with Alexanders Bloodline event?)

Also in the stream I noticed that Dan & co could send alcoholic gifts, will Muslims characters not be able to do so as alcohol in Islam is a big no no?

Thanks.

1. Only one Great Work per province will be supported. This is a hard coded limitation that is very difficult to change at this point.
2. I don't know, I'm not a content developer :)
3. I don't know where we settled on that actually... I know there was some discussion about it being a thing during our time period but that it was frowned upon by religious leaders. But again, I'm not a content developer so I'm not thy guy to ask I'm afraid.

This wasn't always as strict as it is today. Being drunk was certainly frowned upon and sometimes the sale of alcohol was restricted, but in the middle ages drinking wine wasn't uncommon for Muslims. Also some cultures were - and still are - more tolerant of alcohol than others.

Murder and fornication are big no no's for all Abrahamic religions but are pretty common regardless.

Don't forget the Church of the Holy Sepulchre! Particularly relevant for any would-be crusaders, and not located on the Temple Mount.

Probably best just to let Jerusalem develop on its own, as the religion situation will vary from game to game (and unless a player is actively involved, Jerusalem is unlikely to be Jewish-controlled, so best not to have a pre-existing wonder in such an important province that its owners' won't be able to use).

Ah, yes! I knew I was forgetting the Christian "great work" in Jerusalem! Thank you!

Mm, not sure I fully agree. I still think a Temple Mount "great work" is the way to go, given its great importance to the Abrahamic faiths. Despite the Church of the Holy Sepulchre being not on the Temple Mount, I think it isn't too egregious to have it be a part of it all the same. Then again, maybe I'm assuming demolishing upgrades for great works to be something easier to code than it actually would be. Either way, though, leaving Jerusalem blank and allowing someone to, say, build the Pyramids of Jerusalem, would be really awkward, I think.
 
In overall, the more historical wonders are set, the less you can build yourself. I am happy there's not that much already cluttering the world from start.

Indeed. This is why I am fine with neither Jerusalem nor Constantinople having one at start. Those are reasonably likely to end up as player capitals (either for Byzantophiles or for someone doing a real Crusader King run), and it would be nice for them to be free for whatever the player wants them to be (yes, that includes potentially creating a giant pyramid with spikes and dungeons, if e.g. a Norse player conquers Jerusalem and wants to taunt the monotheists).
 
just saw the youtube clip, please add more wonders, like the Library of Alexandria (would mean making two+ great works in provinces available), Hagia Sofia with dynamic religion if that matters, the ruined temple of Soloman with a choice to rebuild it and become the Antichrist maybe, Colosseum of Rome, Aquaducts of Rome, the other varius churches in Jerusalem, make it so certain developed or historically accurate provinces can have more great works, like Rome, Alexandria, Jerusalem, London, Paris, Constantinople, etc...

you said it's hard coded at the moment for one per province, not to sound like an a-hole, though I'm sure this will, but you guys are literally the developers, isn't it your job to figure this stuff out, in the effort to making this game as historically accurate as possible?
