Add a new game mode where you get a random continent or two that you have to take over to win. So it's all random and if there's 3-4 players you get two random continents (two players could get the same one and there might be one or two continents that nobody is trying to take over). But if they take it over anyway they still get bonus troops. And if there is 5-6 players you only get on continent to take over. You don't have to do it exactly my way, you could change it up a bit but there's my idea :)
