I've only played a few of the titles but, of the ones I've played, I'd go with Normandy. Holland' 44 and Ardennes '44 do a great job of conveying just how frustrating it is to get bogged down. Personally, I don't get a lot of enjoyment from experiencing this phenomenon over and over again in a game. In Normandy, the Canadians and a majority of the British units will get stuck in a grinding attrition fight around Caen but the Americans and Germans have lots of room to maneuver around other parts of the map. You don't get that same freedom in Ardennes or Holland....damned bridges...always going boom just as my tanks roll up.....
