Many entrepreneurs started their empires with nothing: Edison, Rockefeller, Steve Jobs, Hewlett & Packard. And Ferdinando, Bocconi's founder, began by selling fabrics door-to-door in the countryside and ended up introducing department stores in Italy, with the Magazzini Fratelli Bocconi (better known today as "La Rinascente").%In light of these famous examples, Bocconi has developed a simulation game which gives anyone who is learning about the world of economics for the first time the chance to experiment with the satisfactions and problems small entrepreneurs face on a daily basis as they manage their businesses.%That's how ICE - Ice Cream Empire - was born.^
