Look at this wild and beautiful map by Mark Herman -- designed for a global hypothetical WWIII wargame for National Defense University in the 1980s. It is currently on display specifically for SDHistCon at the Naval War College Museum.
Now *that's* an innovative map! Buckminster Fuller Dymaxion map overlaid with a hex grid. Coded by terrain type.
Mr. Herman created the award winning Gulf Strike TTWG in 1983.
