I want to love this map, but I just can't. I've been stuck in a game that's down to five players and has been for months. There is no incentive to attack anything. The optimal strategy is to grab hold of a city and keep it because of the defensive bonus. Makes for stupid gameplay.
It's like the classic game, except you might not notice that Australia has an extra entrance. That's fine, but I was playing and didn't notice. That may have cost me the game.
