Sometimes during the game there is a need to switch the country. Most often, this is due to the desire to change the gameplay by taking diplomatic action with another country or simply wanting to make the game easier. Regardless of the reason, changing the country is made possible by the following command:
tag <country tag>
In place of <country tag>, enter the appropriate country tag you want to take over. You can find it in the state tag list or by using the debug command.
