Sometimes my units can spot enemy units (usually barbs) that are three tiles away, even though the enemy units are nowhere near my borders and I don't have any sight promotions with them. I thought normally the maximum sight is 2, and only provided that there are no obstacles like rough terrain.
Is there some rule where your units can see certain things that are 3 tiles away?
Also how close do you have to be to a city-state or its borders in order to officially "meet" it?
