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.
Also, apologies for the boring names in Emberá-Wounaan, but Emberá-Wounaan is a massive chunk of indigenous territory and has no named areas (that I could find).
