core loop

queue construction of buildings -> buildings hire pops and run production methods -> goods trade at shifting market prices -> wages and needs set standard of living and interest-group support -> enact laws and pursue diplomatic plays -> expand industry

design notes

Victoria 3 moves the player's main lever from units to the economy: the player queues construction and sets laws, and pops, prices, and wages respond, while armies are handled by generals assigned to fronts. Politics is an output of economics, since pops' economic status sets their interest-group affiliation and political strength. Diplomatic plays turn war declaration into a timed escalation of demands and counter-demands with a chance to back down (proposal crisis-escalation).

Interest groups

Pops' political strength, from wealth and enfranchisement, flows into interest groups such as the Devout, Industrialists, and Rural Folk; clout is each group's share of the national total, approval comes from laws and government membership, and enacting a law runs phases whose advance or stall chances depend on group endorsement.

core
uses

Population strata

The population is stored as pops by profession, culture, and religion in lower, middle, and upper strata, each with its own wages, needs, and political leanings.

core
uses

Production chains

Buildings such as mines, farms, and factories convert input goods to outputs; switchable production methods change the input mix, output, and which professions are employed.

core
uses

Supply-demand pricing

Each good has a base price, and the market price moves with the ratio of buy orders from consumption to sell orders from production, scaled by market access from infrastructure; prices feed back into building profitability, wages, and pops' cost of living.

Causal breakdown tooltips

Nested tooltips break values into contributing modifiers, extended to battle and market calculations.

uses

Culture and religion conversion

Pops carry a culture and a religion; over time pops assimilate toward primary cultures and convert toward the state religion, and citizenship and church laws decide which identities face discrimination.

supporting
uses

Faction diplomacy

Diplomatic plays present a demand, allow counter-demands, run a countdown to mobilize and gather backers, and become war if unresolved.

supporting
uses

Goods consumption

Pops buy goods to meet needs, and the share met sets their standard of living.

supporting
uses

Labor market

Buildings hire pops by profession and qualification, so labor shortages throttle new industry.

Modding API

Script and data files define laws, events, and goods.

Policy toggles

Laws such as Free Trade and Laissez-Faire change economic and political rules.

uses

Political capital

Authority, influence, and bureaucracy are capacities with monthly supply and ongoing usage: decrees draw on authority and diplomatic pacts on influence.

supporting
uses

Stability and unrest

Pops whose needs fall short become radicals, and radical interest groups can start a revolutionary movement with a revolution clock.

Tech tree

Technologies such as the Atmospheric Engine unlock buildings and production methods.

Territorial control

States change hands through diplomatic plays and wars, and newly acquired states are incorporated over time before they count fully.

War score and peace terms

Each side's war support falls with exhaustion until one capitulates or the sides settle on the demands from the diplomatic play.
