Espionage and gossip are now the primary means of learning the activities of rival civilizations.The developers quoted Theodore Roosevelt as inspiration for their design philosophy, who said that "as civilization grows, warfare becomes less and less the normal condition of foreign relations." Governments can be further customized by mixing and matching various policy cards that are unlocked through the Civic tree. For example, settling a coastal city sparks a Eureka Moment for Sailing. Most technologies and civics have a goal related to their subject that will spark a Eureka Moment when met and substantially reduce the research required. The Eureka Moment mechanic accelerates research time for the Technology and Civics trees.Progress through this tree is made through Culture instead of Science. Civics are researched in a Civic tree parallel to the traditional scientific tech tree.


There is a new game engine with support for a day/night cycle and camera rotation.
