The biggest strategic factor is Civilization's signature “Wonders of the World” improvement these unique city projects are as numerous as they are expensive, so building them all yourself is next to impossible on any reasonable challenge difficulty. This gives you a bit of flexibility in your strategy, though there's only a limited amount of optimization-it's not rock-paper-scissors units progress with each era in a straight-forward manner-it's more about when you get one of one type over one of the other. You're presented with opportunities for peace and trade or war and conquest.Īdvances are less linear than RTS games and improvements are permanent. You research technologies, which allow you to build better units and new city improvements. The premise is simple but has become timeworn: you take a faction from Stone Age primitivism to either global conquest or interplanetary colonization.

Sid Meier's Civilization was a watershed for the 4x genre before the genre even had its present name.
