How about for a new map:
Channel of Doom:
3-hex channel running across map , separating two large islands with mountain ridges on each.
Also various rivers running from mountain ridges into the channel....
the water around the edges of the map would only be about 3-4 hexes wide.
hmmm?
GEEKY!

I can send you simple map editor for game logic

If it is very complicated process, I will likely not get anywhere with it though.
My time is limited, as well as my processor(grey matter pc).
Thanks for the offer, and as usual, your fine input to the MAN2 community.
