Because Sid Meier's Civilization is all about bringing players through history, each game has been broken down into multiple distinct eras. Each of these eras has been themed after a real-world era, like the Bronze Age or Space Age. With Sid Meier's Civilization 7, Firaxis once again has done just that. However, this time around, there are only three ages for players to get through, and with the passing of each age, the entire game is shaken up immensely.
