The THREE KINGDOMS campaign is the heart of the game. Built upon a vast map of ancient China, the campaign is where you manage and expand your empire, conduct diplomacy, raise and move your armies, upgrade your settlements, manage your economy and your characters, and much more.
Reforms advance your faction’s capabilities, the bonuses you gain from certain sources and unlock new building types for construction in your commanderies. You can mouse over each reform to get an overview of the benefits and unlocks it grants.
You can research one new reform in the spring season of every year (each five campaign turns). Certain reforms have prerequisites of two or more branches to research; scrutinise the branch imagery behind a reform to determine those prerequisites.
Factions in the Yellow Turban Rebellion DLC pack have a different reform mechanic which is not tied to the seasons. Instead, they choose a reform to research, which then takes a variable amount of time to complete, based on the reform itself and the faction’s research rate.
Certain resources are required to construct certain buildings. For example, you cannot build a tea house without first owning tea. You can find a list of resources, both those you own and those you do not, by mousing over the resource icon at the top left of the main campaign screen.
Resources can be gained by conquering resource-producing territories, or by arranging trade agreements with factions who own those resources. Resources are not measured; you either have access to them or you don’t. Once you have access to a resource, you therefore have all you need for any purpose, until you lose the commandery that generates it, or the trade agreement that grants access to it is cancelled.
