Victoria 3 - Dev Diary #10 - Infrastructure

DD10.png


Hello again and happy Thursday! Today we’re going to follow up on last week’s dev diary about Markets, which touched on Infrastructure but did not explain how it works. Infrastructure is an important mechanic for the economic simulation of the game, simulating the cost of moving goods over land and creating the necessary, well, infrastructure to support wide-scale industrialization.

So what is Infrastructure then? Infrastructure is represented by two distinct values that each State has: Infrastructure and Infrastructure Usage, which together determine its Market Access. So long as the Infrastructure in the State is greater than or equal to the Infrastructure Usage, everything is fine and the State maintains a Market Access of 100%, but if usage starts exceeding the available Infrastructure, Market Access will be reduced by an amount proportional to how much of the usage is not being serviced.

For example, if a state has an Infrastructure of 45 with a usage of 90, its Market Access will only be 50%. Market Access and its effects is something we’ve already covered in the previous development diary, but to briefly go over it again, a low Market Access means that a State is unable to fully integrate its local market into the National Market, which can lead to adverse price conditions from local over-or undersupply of goods.

Minsk has somewhat overextended their local Infrastructure, but with a large population and mostly staple production both their industries and consumers will probably be fine until the railway arrives

This imbalance goes in both directions. If you have one bread basket state and one iron mining state, and they both have perfect Market Access, the price of iron and grain will be the same in both. If the iron mining state’s Market Access is reduced, the market’s price of iron goes up while the local price of iron in the mining state goes down. But in addition to this the iron mining state will be unable to source as much grain, raising the local price there but reducing its price somewhat across the rest of the market.

If your consumption matches your local production, as is often the case in rural states where the production consists of staple goods your people require, this isn’t such a big problem! You could perhaps even build some simple Textile Mills and Livestock Ranches in the same underdeveloped state to provide cheap wool clothing if the local population is large enough to demand it in sufficient quantity. But if you’re looking to manufacture more complex goods (or use more demanding Production Methods) you need goods you might only be able to source from another state in your market, or which you can only import from a foreign nation. These goods in turn might be lucrative but only if there are buyers for them - buyers who can actually afford them. Your schemes to get rich off Luxury Clothes and Porcelain won’t work if you can’t reach all the far-flung wealthy Pops of your empire.

The Infrastructure Usage of a State is determined by which types of Buildings exist in a State and which level they are. Generally, the more urban and specialized the building, the more Infrastructure it uses per level, so Chemical Industries (a heavy industry building) will use several times more Infrastructure than a Rye Farms building of the same level.

Minsk’s urban buildings - the Furniture Manufacturies, Textile Mills, even the Government Administrations - account for 2/3rds of its Infrastructure usage despite employing the same number of people as the Logging Camps and Rye Farms. Subsistence Farms and Urban Centers do not use Infrastructure, the former because its production is nearly all for domestic use and the latter because the Infrastructure it provides cancel out the Infrastructure it requires.

Infrastructure is provided and modified by numerous sources. Just about all States in the game have at least a little bit of Infrastructure based on the technology level of the country that owns it and its state of incorporation (colonies have lower infrastructure than incorporated states, for example). However, over the course of the game, the most crucial aspect of your Infrastructure is the size of your Railway network. As we’ve previously mentioned, Railways is a Building that produces Transportation, an intangible good sold to Pops, but they are also your main source of Infrastructure.

This means that if you want to industrialize a State, it isn’t enough to simply build those industries there and have the Pops available to work in them, you also need to ensure that said industries have enough infrastructure to support them. This of course has a variety of costs involved in that infrastructure-providing Railways need both Pops to work them and access to goods like Coal and Engines. There are alternatives that can be used in the short-term, such as using your Authority on a Road Maintenance decree to ensure the populace don’t allow the roads to fall into disrepair or become unsafe, but such options will never be sufficient in themselves for large-scale industrialization. Of course, Railways also grow more efficient over the course of the game with such inventions as Diesel trains and Electricity, requiring less levels of rail to support a certain number of Buildings.

This early Railway has rapidly become one of Minsk’s best employers, at least for Pops with the qualifications to become Machinists. Unfortunately few people do, so the Infrastructure production is not currently as high as it might be if the railway was fully staffed. Ticket prices, however, are sky high.

Our intention for railways is that they must be able to find their way back to the market capital, or an exit port destined for the market capital, in order to be useful. In effect this means that any railway can only provide infrastructure up to the amount of infrastructure provided by the best adjacent railway that connects it to the market capital. If you want good access to the Sulfur Mines in Aginskoye for your Munition Plants in St. Petersburg, you best get started on that Trans-Siberian Railway sooner rather than later, because it will take a good long while to build.

Geography, of course, also plays a significant role in other ways when it comes to Infrastructure, and this is represented in Victoria 3 through State Traits. State Traits are bonuses and/or maluses given to a particular State representing particular geographical features, climate and so on. State Traits have a variety of effects, but the most common ones are to either affect the production of a particular resource (for example, if a State contains high quality coal this may be represented through a State Trait that makes coal mines in the state more efficient) or, more significantly for the topic on hand, to provide or modify Infrastructure.

The high-yield Russian Forests are of great benefit to the Logging Industry in Minsk, as long as there’s enough infrastructure available to ship the wood off to all the Russian factories and construction sites that demand it.

States with significant rivers get a large boost to Infrastructure, making them excellent candidates for early industrialization

Before we finish up for today, I also just want to mention that Infrastructure does tie into a number of mechanics besides Market Access, such as military logistics and migration, and that Infrastructure is only meant to simulate the cost of transporting goods on land - where the sea is concerned, there are other systems at play… but all of those are topics for another day, so for now I bid farewell and encourage you all to tune back in next week as Mikael returns with another economy-related dev diary about Employment and Qualifications.

Great idea to simulate the cost of transport.

What have you planned for competing infrastructures? As other posters have said, there were canals, rivers, roads, etc.. all of them will be adding to the infrastructure capacity or there will be some competition between them? Is there going to be competition between private/public transport companies/industries that make a profit on the usage of infrastructure?

Is there a limit on how much you can build? do you have benefits by ditching an old infrastructure to make way for a better one?

Question:

How does Infrastructure work if dastardly foreigners' wars or diplomatic plays split my country in two and deprive me of all ports connected to my capital?

(Asking for the AI.)

If infrastructure strength is based on the connection to the market capital, what does that imply for local "pockets" of states that are difficult to connect to the capital?

To use the Siberia example that was provided in the dev diary, let's say that I'm Russia and my Far East coast is built up with rail, but I don't have a great connection to my market capital (or it was disrupted by a war or event or whatever). If my trans-siberian railroad is bad, but my connection between Khabarovsk and Vladivostok is great, can those two states access one another's goods easily, or does the game only calculate access between each state and the market capital?

So this will also mean that if 2 neighbouring states are completely cut of from your trading capital for whatever reason they would not be able to trade with each other despite perfect infrastructure in these 2 states and each needing the others neighbours goods?

One thing about the railway connection - it seems it will be possible to cheat a bit on the infrastructure costs. Like if state A is your market center and you have states B, C, D, E, F in a line, each with good requiring 100 infrastructure, then you can get by with 100 infrastructure in each. But if it's supposed to represent the ability to ship goods to the market center, then E would require 200, D 300, C 400 and B 500 as more and more goods would be moving over the rails as you approach the center.

On the other hand, in reality the goods wouldn't all have to reach the center, so probably good enough.

Regarding building of long railroads, like the transsiberian railway: Do we have to build one section at a time, or can be build simultaneously in say 5 provinces at a time, thus making the building quicker? I guess there should be a limit in regards to this due to the, ahem, infrastructure needs to transport the resources? :p

Excellent addition:

For History sake, USA had a great problem exploiting the hinterland plains and mountains far from navigable waters before railroad it was cost-ineffective to do export activities un such areas. The regions suitable for such export (and import) activities remain the coastal ones, the ones who had access to the Mississippi and the Great Lakes (there was a canal built there to New York). This lasted until railway could be everywere and homogenized market access.

A similar thing happened with Russia, the areas without navigable waters (canals, Rivers, sea) reminded quite backwards and underexploited until the railroad arrived.

Argentina, Brasil, Australia also had a huge leap in producton when railways started to connect the hinterland with the capital.

It seems the Game is representing this and Iam very happy with this addition, congrats.

Cool, this seems to be improved from vicky 2.

Question: Will there be something for canals?
Canals will for sure be a thing, at least the major ones like Suez/Panama.

Oh hey, quick question: will there be an infrastructure map mode? That seems like it'd be pretty useful

Seems pretty interesting, is the Danube and Rhine as well as the Meuse rivers giving infrastructure if not are we able to mod them in easily?
Our aim is for all major rivers to provide infrastructure in varying amounts, the Rhine and Danube for sure count.
