Countries are large territories marked on the map, that consist of 2 or more adjacent regions which are controlled by an alliance.
To create a Country, your alliance has to build a Capital in one of your controlled Regions and combine it with other adjacent regions.
Countries can grow by adding more adjacent regions, but they must always be connected to your existing country. An alliance can have multiple countries with different benefits but can also merge Countries and keep the highest upgraded benefits of both merged Countries.
Countries provide significant benefits to all habitats within it and add a layer of strategy to alliance wars.
Attention: Regions and Habitats continue to work like always and region benefits aren't lost when it becomes part of a Country.
