Game is realy epic, but i think can become better. For example, you can make negative weather conditions, like spontaneous drought or earthquake, which can not be call by totem. Maybe it bad idea, but how about land and sea monster? They can attack when notice people or settlimets and can throw fireballs or approach to melee combat. It would be funny if peoples build not only fortress, but farms, mines or other buildings, which be decorative and create the impression that they live like real people... Maybe be good if you add animals to game, like wolf or deer.
