Actually, if it goes down to Africa, North America, or the Islands versus any of the non bonus countries, Africa, North America, or the Islands would win. If the las two countires are both non-bonus or africa and north america, the game wont end. If the last nations are Africa or North America and the islands, it would actually be an interesting battle.
I'm rooting for North America and the Islands, because I wanna see how that will turn out.
