C-evo is an empire building game, dealing with the history of humans from antiquity to the Space Race. This includes aspects of exploration and expansion, war and diplomacy, cultivation and pollution, industry and agriculture, research and administration. Players must constantly make decisions such as whether and where to build cities, roads, irrigation, and fortresses, whether to form an alliance with a neighboring nation or risk attacking it, and whether to devote resources to education/research/production, warfare, or the well-being of the populace.
