Ok, so first you say something that is wrong : There is some Belgium fortifications represented in the game at Liège.
Ok. I loaded AoD and HoI 3 back up. You are correct about most forts. Depending on the scenario and the game, there are either forts right where you say there should be some (try HoI3 "Attack on the West" 1940 scenario) while my games versus the AI, France and Belgium did not build the forts in Sedan and Maubeuge and Hasselt, respectively. In AoD, yes there is a lvl 2 fort in Liege. And in HoI 3 it's Liege and Namur with 3 and 1 default. So I yield on that issue.
Then, nothing contradictory in your statement ? You say it's almost useless, but you don't want them in the game because "for gameplay purpose, there is little reason to give France more chances to defeat the German AI and ruin World War II." And by the way, it's not because you said it was useless that it really was. I began saying that : "1°) There should be some Franco-Belgium fortifications, even january 1st 1936, but they were way less strong and efficient, and auto-sufficient than the Lorraine ones, for example. But there were, until North Sea." So we can agree I guess. I don't wan't a fantastic wall, I just want the historicity to be represented. I don't "think it's misrepresented", it is.
I know we have a language barrier, and I have a little trouble understanding what you mean, so bear with me. I understand you agree, but I have to call into question the need for more forts.
By "it's", I assume you refer to the fixed defenses? And yes. I think they are generally unnecessary for the scale of the game and the goal of the entire first year of the war. To say that most people really want France to stop the Germans somehow and have a WWI v.2 is ambiguous at best. And France, like much of Europe, need to be designed so Germany can actually become a threat to countries like Russia and the US. I know the people who play those countries don't want to see the Red's and French shaking hands in Torgau in 1942. Booooring! Might as well dump the entire Heer in Norway in April 1940 and call it a day!
I still question the giving of France (and Belgium by the basis of your argument) these forts in 1936. So a human player can ramp up the "Maginot to the Sea" by 1940? Are you concerned that the number of fortifications in France are the root cause of a French defeat? More would mean a bigger chance of the AI Germany dropping the ball in 1939/1940 and by 1941/1942 Russia moves in and it's game over December 1942. Less would actually be better for people who want to make sure WW2 starts and doesn't fizzle as some regional conflict. Much as I say to the people who want the Czechs and Poles to "defeat" the Germans, it just doesn't make for a fun WWII game.
Finally, I can't get that point : "It would be a contradiction of history to represent something for it's expected function as opposed to actual results." That's just insane... Why should the devs distort historicity just because it didn't eventually get the expected efficiency ?!
I'm referring to the idea that making something in a game because it was historically intended to do something, yet did not. The main Maginot Line was very successful in it's purpose to deter attacks across directly into France. The line to the north, whatever it consisted of, was wholesale cracked and bypassed in such a way that, to increase a generalized representation of fortification present on the line, would risk ahistoric French/Belgian/Allied success. That which a factually numbered French army would also do. If all INF being equal (as so far as tech goes) then even without
any fortifications, HoI games would most certainly turn to stalemate quite often in 1940 (assuming France's huge army wouldn't just walk to Berlin while the Wehrmacht was busy in Poland). It's a historical equalizing. Unless you know how to represent the many nuances that actually led to French defeat, I'm glad it works the way it does.
So yes. The devs have to distort history to create a game with a period setting.
There are many things that surround creating a fun and believable scenario for Germany and France in 1940. I certainly don't want an easy fight (I've been as late as November 1940 to beat them once!), but I don't want a walk in the park either (5 days to Paris, 10 days to Vichy is my best).
Thanks for the links to those articles by the way. Some nice maps and good info the en/wiki doesn't have.
