Sid Meier's Civilization
Anarchy is a breakdown in government resulting in the absence of political authority or any cohering purpose. The government ceases to function, along with any services it provides. While anarchy has been seriously proposed as an alternative to government, it has never achieved more than fringe acceptance. Anarchy has occurred at various times in history following great social upheaval caused by revolution, war, natural disaster, or disease. In almost every case, anarchy meant panic, disruption, waste, and destruction.
Squares producing three or more of any commodity have production reduced by one. For example, a square that normally would produce three food produces only two under anarchy. Units up to city size do not require maintenance. Military units in a city decrease unhappiness. No taxes collected or knowledge accumulated.
