Land double blind game. Just saw a copy of double blind The Normandy Campaign which was bid from the eBay. The components still look very nice and intact. GDW produced games when I was too young and didn't have the money to buy any game for myself. So I missed most of them. But did the double blind concept to wargaming really work for a land campaign game? I don't find any problem with he sea games but for the land, it appears that the experiment didn't work out by either GDW or 3W.
