A collection of Steam game keys for the Civilization games series and its downloadable content in one perfect pack. Civilization series includes turn-based strategy video games and has been around us since its first release in 1991. Over time, its developers have not only launched new concepts and features but have also made impressive graphical advancements. The main concept around which the whole game series revolves is building civilizations from early history to the not-so-far future. This series has been known as the 4X game series in which victory against other humans and computer-controlled enemies is achieved by eXploring, eXpanding, eXploiting, and eXterminating. The player selects a civilization first and then makes progress towards its development. And to do so, the player will supervise the civilizations’ government and its economy, handle trade relations and diplomacy with other civilizations, take care of the technological and cultural needs, and may also involve in a fight against opponent civilizations.
