when someone controlled 3 or more continet and u have 0-2 and others like u, it makes everyone very hopeless and the one having 3 continents obviously win if no one decide making alliance against him,
I suggest adding Rebels to the game!
for example the one who had 3 continents will lost some provinces in the weakest continent and that gives chance and hope to others, rebels might come back to the one who have more than 3 continent but they are easy to defeat and don't give any cards.
