Bonus values are however many outside territories the bonus has, -1. Though some may think it unbalanced, I think it makes for a good strategic map--rather than focus on expanding, you must focus on defending. It's not at all easy to win.
Note: This map was made with FFAs in mind. In 1v1 situations, it can become quickly unbalanced. 4+ players recommended.
I understand the desire to maintain the scale of the map, but the territories are very small and hard to see. Also, the bonuses are atypically low in many cases (e.g., 1 army for 5 territories) and somewhat imbalanced. That being said, this map is quite good. 4 stars.
