Who cares what board is under that pile of overlays. Is there any original hex from the mapboard that is still in play without having been covered by overlays?
No boards. Gavutu-Tanambogo used to be all overlays, but MMP ruined it.I believe the scenario Water Fowl from Operation Veritable HSASL uses overlays on ocean overlays. I don't think any boards were used, if there are boards it is only to help setup the overlays.
