Civilization: Call to Power is a turn-based strategy game. One of the most noticeable differences from the previous Civilization games is that the timeline of the game does not end in the 21st century, but rather goes to the year 3000. There are five epochs in this game: Ancient Age, Renaissance, Modern Age, Genetic Age, and Diamond Age. Call to Power adds a more thorough space colonization as well as sea colonization, with the appropriate technological advances (wikipedia.org).
