Still. How to determine which side a squad is. When the squad size is physically almost as big as the hexagon on which the river runs?
Answer 1: A river runs through? It is an entire water hexagon. The banking doesn't matter. It is for water units only.
Although, if a river contains sand, grass or a bridge etc. Then this is a chokepoint for both land and water units. Of course, depending on the design.
Answer 2: A lot, really a lot of wargames, have a river going over the "ridges". I could still do this.
As for the rules. I guess those units that can cross small bodies of water. Can cross these rivers as well. And crossing a river or ridge does mean, that the unit moves INTO that region. And the SMALLEST space counts for the movement.
As for the graphics. Well, I don't see any other way than simply not having answer 2 in this regard? Well, that is wrong. I realized that I SHOULD have these rivers as well.
I will design in a digital way. But the graphics would certainly be a challenge.
Answer 3a: Both!
River through hexagon? Body of water.
River over the borders of a hexagon? Simply a wall.
Answer 3b: If I really want to be nitpicking. I could always have little tokens in the players colour. And have them stand on the side (the border) of where the army is standing.
***
A river as body of water would have been 100% water.
A river that splits the terrain in 2? From N to S. 50% water, 50% ground. Of which, both are 25%.
Well, that sounds all logical. But If we observe the way where the river goes. It would be better if I cut the hexagon in 6 portions here. And 2 portions are mostly water. The 4 other portions hardly have water. This "mostly" is what counts. It means that here there is also "ground". In a sense, I could say that a river the has 1 entrance and exit. Counts for 2/6th as water.
If multiple sides are water, then each side counts as a 1/6th portion. This way, it would even be possible to have a hexagon with a pointy spot that counts as only 1 portion. Thus 1/6th of land. On which 600 worth of value can be. A little token for that player would be on the side. Just for the funs I guess.
Then, because they cannot move into water. They can a bonus range of 1 in this direction. A small hexagon that can server as a sniping spot.


If a river runs through a hexagon. I am having it go at 90 degrees through a "ridge". You often see games with a river going between hexagons. I rather not do that.
And voila.
If a river ends at a hexagon. It ends in half the ridge. And the other part of the ridge can pretend to be a rocky formation with a cave, from which the water comes.
Still. How to determine which side a squad is. When the squad size is physically almost as big as the hexagon on which the river runs?
