hmm, dont know if I get it right.
you could use a underlay with the marsh and overlays for the rest..
Maybe toy around with using all or some of the checkboxes when creating the overlay.
Or move/bend a level one ground hexside from K32-L31 over ther…
I think so, too, I have the "Handy Rotary", "Power House" and "Balloon Busting" modules. My group once played with 8 players, it was a blast
Is there a VASSAL module for this series of games ?
