Nice quiz! But many countries didn't light green on the map (Mexico, Brazil, Chile, Argentina, Namibia, Botswana, Mozambique, Madagascar, Mali, Morocco, Algeria, Australia, Saudi Arabia, Oman, UAE, India, ...) Probably those that are "cut" by the tropics and are not visible as whole?
The US and France should be included. Hawaii is an integral part of the US, not a territory. Same thing with Guadeloupe, Martinique, French Guiana, Mayotte, and Réunion. They are departments with the same status as Metropolitan France.
