A scenario map.
I tested here a Commercial Monopole.
You need to have at least 16 trading posts to win.
Against you, are 7 AI-players and 6 AI-natives.
Even if minor natives cannot populate, they can do
more damage if you walk near them.
You evoluate inside French Alps Mountains, around Grenoble (Winter Olympic Games 1968) where snowed summits and deep valleys have lot of surprises.
