Historically, a civilization was a so-called "advanced" culture in contrast to more supposedly primitive cultures. In this broad sense, a civilization contrasts with non-centralized tribal societies, including the cultures of nomadic pastoralists or hunter-gatherers. As an uncountable noun, civilization also refers to the process of a society developing into a centralized, urbanized, stratified structure.
Sid Meier's Civilization is a turn-based "4X"-type strategy video game created by Sid Meier and Bruce Shelley for MicroProse in 1991. The game's objective is to "Build an empire to stand the test of time": it begins in 4000 BC and the players attempt to expand and develop their empires through the ages from the ancient era until modern and near-future times. It is also known simply as Civilization, Civilization I, or abbreviated to Civ or Civ I.
Civilization is a turn-based single- or multiplayer strategy game. The player takes on the role of the ruler of a civilization, starting with one (or occasionally two) settler units, and attempts to build an empire in competition with two to six other civilizations. The game requires a fair amount of micromanagement (although less than any of the simulation games). Along with the larger tasks of exploration, warfare and diplomacy, the player has to make decisions about where to build new cities, which improvements or units to build in each city, which advances in knowledge should be sought (and at what rate), and how to transform the land surrounding the cities for maximum benefit. From time to time the player's towns may be harassed by barbarians, units with no specific nationality and no named leader. These threats only come from unclaimed land or sea, so that over time there are fewer and fewer places from which barbarians will emanate.
The BBC remastered the original films onto HD in 2011. The series was re-broadcast on the BBC HD channel from 9 February to 4 May 2011, and shortly after was released on Blu-Ray. In 2014 the BBC announced that it intended to make a new version of the series, sparking some debate as the best approach to take.
Civilisation was one of the first United Kingdom television documentary series made in colour, commissioned during David Attenborough's controllership of BBC2. For technical reasons, colour television was to come to BBC2 before BBC1 and, as a channel aimed at a more highbrow audience, it was appropriate to commission a major series about the arts. It was Attenborough who prompted the title, but because of time constraints the series only covered Western Civilisation. Clark did not "suppose that anyone could be so obtuse as to think I had forgotten about the great civilisations of the pre-Christian era and the east", though the title continued to worry him.
