AtlasMC is a Towny geopolitics server where players build nations and deal with politics. It is all about diplomacy alliances and wars that players start and shape.
During beta the map is only Mediterranean Europe. The plan for later is a full Earth map when it fully releases.
It uses custom plugins made for long term gameplay. There is a geopolitics plugin with vassals titles and Great Powers. There is also a PvP battle points system so fights have real goals and points.
