Hi all,

I’ll be posting the dev diary on behalf of @Braindrift today, who’s taking us through the details of the Great Wonder construction feature which comes in the Heirs of Alexander pack!

Great Wonders
The Heirs of Alexander content pack will include a design-tool which allows you to assemble and construct your own Great Wonders. The tool gives you a 3D view of your construction, and once the building is completed, your creation will be represented on the world map.

The Great Wonder construction tool window

You have 3 different categories of constructions to choose from; pyramids, towers and buildings. Each category has their own set of modules, like bottom, middle, top for towers, that can be interchanged and combined within each category to create the shape you’re going for.

The Great Wonder design window is reached from the building tab in the territory view, once there is a Wonder under construction, or completed, a fourth tab will appear that displays relevant information about your creation.

Materials
Each module has a material, the default is stone, which is considered to always be used as the main building component for a construction. Other examples are silver, ivory and marble, in total there’s 9 different materials which each affect the look on the module they’re applied to. To be able to use a material, you need to import its related trade-goods to the province in which you build the Great Wonder. If you for example have set one of the modules to be covered in silver, you need to import Precious Metals to the province. If you ever lose an import route, the progression of the construction will be halted until you’ve set up a new route for the required goods.

Model and material variations for some towers - Edit: More variations and categories at the bottom of this post

Effects and Prestige
Your Wonder can have up to three effects, which are basically powerful modifiers, some with unique aspects that can’t be found anywhere else in the game. Some effects can only be used by unlocking the corresponding invention in the technology trees, while others are accessible to all. Each effect has four tiers, and the construction's prestige value is what decides what tier you can choose from. The fourth and final tier can’t be reached during the design phase, instead the Wonder has to age for some centuries, until it has accumulated enough prestige to be upgraded with the top tier effects. This means that the simple stone tower you built in the beginning of your journey can grow and become as powerful as the pompous gold abomination your neighbor saved up money for, but couldn’t complete until late game. Of course, this puts the burden on you to protect your cultural treasure, as prestigious constructions become highly attractive to conquer.

Costs, construction time and construction leader
The construction of a Great Wonder will be a massive undertaking to complete, even for large and advanced civilizations. There’s always an upfront cost in money from the treasury, which will be decided by category, materials and what effects you assign. The same factors affect the amount of work that needs to be done, but the final construction time is based on the number of slaves, tribesmen and freemen you have available in the province which the construction is built in.

Construction time is further affected by assigning a construction leader. Similar to military and naval leaders, there’s a significant dent in efficiency without a leader assigned, the construction speed being decreased by 25% without one. The governing stat for construction leaders is Finesse, which will speed up the construction by 5% per point.

We’ve also expanded on the character traits to make them relevant when choosing your construction leader, giving them effects such as improved slave efficiency from the Harsh trait, or some added construction prestige value from the Polymath trait.

There will also be a Political Influence cost, related to what modifiers you add to your construction. More powerful modifiers cost more PI. Upgrading or changing modifiers will also be related to a PI cost.

Ancient Great Wonders
As a part of the Marius update, we’ve also brushed up the good ol’ Ancient Wonders such as Stonehenge, Colossus of Rhodes and Lighthouse of Alexandria. Each of them now have one of the tier 4 effects that you can use for your own constructions, making them both valuable assets to keep within your domain, and attractive targets for conquest. There’s also a number of events connected to the wonders, giving them some story and an additional management aspect.

Will the AI be able to build those wonders? I already imagin to see those towers all over the world...

In the end: nice to have but also not really the selling point for me especially the towers. I would be more interested in Grand Temples etc. A grand Jupiter temple or a new Pantheonstyle thing would be much more interesting. I am also curious why Pyramids are a catergory. Maybe because they already exist und you have them in? Do we really have the ability to built pyramids? Strange, since there are no real Egyptians around at the time that practice that.
I like having ahistorical options embedded in historical settings. So I could turn Denmark into a pyramid wonderland, or set for myself as a goal, the construction of a huge tower on the tip of Somalia. I love it when such decisions are mine to make.

It’s concerning that you’ve added another finesse job but no charisma and zeal jobs. will these 2 become unimportant?
Charisma "job(s)" should be added, when diplomacy gets updated.

Maybe for Zeal a job can be found in the future aswell.
What happens if a tile with a GW becomes decolonized (due to conquest or natural disaster?)
Personally I would hope that territories don't automatically lose ownership, if no pops inhabit it in a future update to avoid these "holes" that sometimes occur. Maybe allow adjacent nations to colonize such a empty territory peacefully, but giving the former owner a casus belli.

Looking good, but one word "Colossi"
 
For things like the Alexander the great body event, would you be able to move his body into a custom built wonder you've built and have a shrine visible on the map?

Question: will there be regional differences? I don't want to see a pyramid in Jylland or Juipter's temple in Bhutan. I do hope that different cultures/regions/faith have different and/or unique wonders they can build, even if it is in another dlc. In addition to that, would the previous(and future) favor packs grant new wonders and new parts?

This looks genius! thank you.
Will you be able to re-dedidate an existing wonder for a new purpose and change design/effects once you have controlled it for X years after changing culture or religion?
 
The effects on the wonders are not stackable, if you've used an effect on one of your wonders, it won't be possible to choose the same effect again.
If I built a wonder and gave it some effect, and my neighbor also built a wonder and gave it the same effect, what happens if I conquer the land that wonder is in? Will they stack, or will one deactivate, or something else?

This looks nice. Can we build universities this way?
Takshashila in India was an already functional university in this era (and has its own unique model in the game), so I think it is a good candidate for a prebuilt university wonder. :)

@Arheo Can we get some more Levy/Legion unit comparisons for the many that we haven't seen yet?

Looking at the game files vs the ones we've seen (Arabian, Celtic, Greek, Roman, Scythian, Iberic)

There's still quite a few missing, namely the North and South Indian, Persian, Nubian, Egyptian/Numidian/North African, and German.

Can i build the Walls of Constantinople?
Some sort of Arsenal, a la Venice and Carthage?
Great walls, great temples, lighthouses and libraries.
Can we have more than one per city? Maybe two for a metropolis, and/or an additional one for the realm capital? Cities like Alexandria and Rome should be really special. I'd love if a lot of the existing modifiers and buildings are added (eg Parthenon, Campus Martius etc.) And unique missions for Rhodes to build the Colossus!

I'd like Jews to get different ones

Actually we need more Jewish flavor in general.

Pyramids are a real bad example, since they were build by multiple different cultures that had no contact with each other. It's a form that results from the question "what if we piled up some rocks realy high?".
Towers have the same issue. There's some reason why people are fascinated by tall phallic structures...

Buildings on the other hand should be specific for each culture group, since their destinct architectional style were unique to the civilisation building them (except when it comes to the romans, since they copied everyone).
Yes and no. A piled up stack of rocks is hardly a wonder of engineering. The egyptian pyramids are. Wouldnt you agree that it would be weird if german or any other culture would start building mayan style pyramids?

I don't know, given the history of Germanic peoples up to the game's timeframe I wouldnt have expected their most wonderful architecture to end up being based around an obscure middle eastern religion; not sure if building to some natural geometric shapes counts as a less likely direction to develop in.
