from the Eurogamer interview:
Eurogamer: Sorry to ask a purely functional question, but there's something I'm not clear on - how do you decide what archers can see and what they can shoot?
Jon Shafer: They can shoot over things, if they're up a hill. The range is the same, but if they're in a jungle, all they can see is the jungle. But if they're on a hill and there's a forest between them and the enemy, they'll be able to shoot over it
I think this is MOST exciting news!
So terrain REALLY is an important factor - more tactics!
I just hope that for archers it is impoosible
to shoot 2 hexes over hills/mountains, no matter they are on hills...
Also not to shoot over "wood"-tile form lowland-tile...
