Supreme Ruler 2020
Supreme Ruler 2020 contains almost all of the current world's countries and many sub regions, such as divided nations or some states and provinces. The game currently supports up to 255 regions to run on the map at the same time. The two primary starting maps consist of either 184 countries or 249 countries.
World 2020 includes 184 countries and is closely related to the world in the year 2008. Some countries in the world that are not internationally recognized or are too small of a scale to make them their own playable region have been combined into other regions. World 2020 in Crisis is the World 2020 map with the conflict and relations amplified. Wars break out sooner and alliances are easily formed.
Shattered World/Melting Point includes 249 regions. Many of these regions include larger world countries divided into pieces usually along border and state lines. At the same time, many smaller island regions have been grouped into a new region called the "UN Protectorate". Melting Point is the Shattered World map with relations amplified. Wars break out sooner and alliances are easily formed.
Additional Maps usually start from either of the above mentioned maps. Further groupings can occur and scenarios can be built from the maps to offer players specific objectives and appeal to a variety of play styles.
