I wanted to thank you Chevalier for putting so much work into this game (and the first two)! It's been a pleasure reading through these illustrated depictions of tactical wargaming even though these are not games that I would want to play myself. For the Great War game, I think the biggest reason for your success was something that sounds simple but isn't: having the requisite patience not to act for long stretches of time. Most players, much like the real-life generals in the Great War, tend to get antsy and insist on doing something for the sake of doing something even when it isn't strategically wise. You did an excellent job of building up your forces to make decisive strikes and being perfectly content to have nothing take place on the Western Front for long months in-game / long weeks in real-life. A lot of lives could have been saved on the Western Front if the actual Entente commanders could have had the same strategic patience!
