Damn you Madagascar!
Out of the 7 times i've played this game, its always that one country that never gets infected. Its been the only country not infected 3 times as well. Its way to hard to infect them, since they have no borders or airports.
If you're going to make another game with this format, I suggest either allowing choice of starting location, or fixing the difficulty of infecting that one area. (I've also had small problems with New Zealand, but its not as bad as Madagascar).
