Knowledge is power, as the greater thinker Bacon put it. Through the game, you will know how wise the English man is. In the game, you will have to rack your brain over and over again, to spend oil as less as possible, and plough the farmland as much as possible. Oil is limited, but I am sure your brain have unlimited ideas. You have story mode and free mode to choose from, it is really a tough game with intersting, enjoy it!
