World Domination is a real-time strategy game that uses the Stratagus engine and was inspired by the Axis and Allies board game. It is unique amoung RTSes because it does not require you to havest resources. Instead, you receive money based on how much territory you occupy. This allows the focus of the game to be on combat and not the management of workers.
