I.T. Kid

You are Arthur, the young noble ruler of Cornwall. You are set to defeat all the neighboring kings and queens, concur their kingdoms, and bring their people freedom, prosperity, democracy, and all that other good stuff that comes from brutal despots and other politicians. To achieve your goal, you attack your neighbours with a catapult and kill their soldiers with your own sword. That'll teach them how to defend their land! Like in the real life, every killing brings you more money, you spend it to buy more troops and weapons, and perform more killings, and so on. Enjoy.
