Others may differ, but I agree with an earlier comment that the borders are difficult to read, making it tough to tell if you've got a province under control for the bonus. Trying to compare the board to the map in order to figure this out is tough too as the board does not look as clear as the map, especially during game play with opponents next to each other.
Great board. In two player mode though, the player going first generally has a seemingly significant advantage over the other player. Is there a way to include a few neutral territories to help minimize this, especially in games with medium and heavy fog?
