This is going to be good! I have a completely different strategy in my game, but for this one....
You could Finnish the Graff Spee (that much production for what, 6 days in exchange for a CA isn't too bad), but concur with Otto as for the navy at this stage.
I would like too see how an initial Inf & Armor buildup looks.
I would love too see the main map with all moving units highlighted at the start of a campaign!
I love it that you are doing this!
