way back in the reddit AMA, the question was brought up:
Hi, I was just wondering about the sight on the map that you’re playing on. Will you be able to see the whole of the map at once and everything that happens on it or will you be forced to like send villagers/soldiers to investigate certain parts of the map (fog of war). Keep up the good work. This game is going to be epic.
We are planning on fog of war.
