国家理念

The government tab containing the national ideas sub-section.

Much like in its predecessor, Europa Universalis: Rome, the player can tailor their country to achieve particular goals by picking national ideas.

Mechanics

There are 36 national ideas the player can choose from. Each idea has its own bonus and belongs to one of four categories corresponding to the power types in the game. Some ideas are available from the start, while others are unlocked by advances during the course of the game. Selecting a new national idea costs 50 Civic power.

The number of active national ideas depends on the country's government type. As a rule, tribal governments can have two national ideas, while the more advanced government forms, like republics and monarchies, can have three (though there are exceptions to this rule).

Each government in the game comes with a base bonus specific to that government. There is also a secondary bonus for each government, that is unlocked if the picked ideas correspond what is expected by that government form.

For example, in the screenshot Carthage is an oligarchic republic. This means that they can pick two civic ideas and one oratory idea, to receive their additional bonus. For Rome, which starts as an aristocratic republic, this means it needs two military ideas and one civic idea to get the additional bonus.
