While we were trying to figure out how he broke the game and to what extent, we noticed that he had no national spirits. In fact, he didn't take any of the defensive focuses. Now, I know you can extend the Maginot line.but that's not what they did. The first hint that he was cheating was that he had level 10 forts along the Belgian border. I saved and loaded the game afterward to see what they did and took screen shots. The France player somehow cheated in multiple ways. This was the worst case of cheating in a game I've ever seen.
