The mechanics for Building Ownership are completely revised in the 1.7 update so that the owners of a building no longer have to work in that building, or even live in the same state - London-based Capitalists can now own buildings all over the world, and buildings can be selectively nationalized or privatized and put up for sale to interested investors, with the available options being restricted by which economic system a country is operating under. Additionally, buildings can now potentially have a different owner for each of its levels.

Power Blocs are multinational associations that can be formed by high-ranking countries, and which take a variety of forms based on their Identity and Principles. Power Bloc Identities are set when they are formed, while Principles can be added and removed over time. Power Blocs are highly customizable in other ways, such as choosing their name and customizing their emblem, as well as creating custom statues to reflect the glory and reach of your Bloc.

Hell yeah, gonna form the Warsaw Pact
