Dictatorship

A Dictatorship is a government in which a single ruler or political entity assumes full authority (as dictator). In the real world, it is more common in Third World countries, such as those in Africa and South America, where a single would-be ruler can easily obtain the country using "less legitimate" methods.

Gameplay
Dictatorship offers a single player the highest degree of freedom in running their country, along with a large amount of power. However, it can often increase the risk of rebellions and decrease dimplomatic terms with countries which don't use a dictator.
