Goat Simulator has already sold "almost" one million copies, Coffee Stain Studios explains to Joystiq, noting this means the surreal game that started as a joke made back the developer's initial investment in "ten minutes," generating more revenue in four months than all their more serious efforts earned in the preceding four years. They explain that they realized they needed to actually develop the game when the humorous trailer they created for the premise collected more than one million views. Thanks nin.
