Why I have the feeling that this is the inspiration for the Frisian Islands Landing nonsense?
I wonder if Im the only gamer alive that remembers that game replay in the magazine. The Third Reich maps continued to be published with a "Beach" hex on a Frisian coast hex on all the editions of the map. If you were not guarding it with fleets placed in a port there, then you parked a infantry corps on it. So thousands of the players of that game pondered the threat of a unguarded coast.
Another outlier was a game where I saw the Soviet player pick off Sweden late 1943. it looked like wasted resources, until in 1945 he used airborne forces based there to make a last minute coup capturing a couple Victory Point cities in Germany which the US/Brit player had been counting on. That made for a net shift of two points giving the Soviet player highest score in the final count
