Mission of Oiligarchy is to get your hands on the world's oil reserves and become an oil tycoon. Explore oil, Trash the environment, bribe the politicians and drill and pump as much oil (petroleum) as possible! World War 2 is over and the future looks bright for the West. Your new office is on the top floor of one of the biggest oil companies in the world. Your task as CEO is to turn that black sticky stuff into gold by any means necessary.
Mother Nature hid her dark treasure in Earth's bowels. Use the exploration vehicles to find the reservoirs over land or sea. Found a deposit? Deploy a small well, a normal well, or a platform making sure that the drill line hits the oilfeld and starts the extraction. Remember that when the reserve on an oilfield is half depleted, the rate of extraction will decline gradually and you will probably have to supplant this loss of producitivity. Have fun with Oiligarchy!
