"Civilization is a series of turn-based strategy video games produced by Sid Meier. Basic gameplay functions are similar throughout the series, namely, guiding a civilization on a macro-scale from prehistory to the present day.

All titles in the series share similar gameplay. Each turn allows the player to move his or her units on the map, build or improve new cities and units, and initiate negotiations with the computer-controlled players. In between turns, computer players can do the same.

The player will also choose technologies to research. These reflect the cultural, intellectual, and technical sophistication of the civilization, and usually allow the player to build new units or to improve their cities with new structures."
