Am I understanding you to say that the main reason that terrain in Normandy and Kursk were different was because the French farmers hadn't trimmed the hedges? Really?
You understand incorrectly.
The Germans used wisely what they had. They were fighting in a plain (the very same plain of Belgium, Holland... etc etc and Kursk, all the way to Mongolia). With natural ditches (ergo no need to dig them) Later in the Low Countries (same plain) they found other natural ditches (the canals). I don't know if they had a green wall there too.
All we know is that defence in late spring '44 managed to slow their enemies down. The very same army that had fought in Italy. Had the Red Army fought at the same pace to liberate their land... well, the Germans would still be fighting in the 50s a tactical withdrawal somewhere near the 1941 border.
You can't make an omelet without breaking some eggs.
And yet, the bocage was not a problem in 1940
Overhyped is not an issue imo. A wargame should try to recreate a war that already happened. The Anglo-saxons of '44 had problems piercing that defence? Well, a game must reflect this.
Now I get it.
