Just reading these devlogs makes me want to learn Unity coding in order to perhaps help you a little bit with this game. Too bad my laptop isn't built very well for programming ^^'
And also, could I make a suggestion? If there isn't a mechanic like that yet, could you implement a mechanic so that you can still add unorganized bands on a cell even if you already put them on the beggining? Just so that I can populate continents that weren't sailed to and colonized.
