I’m pretty excited about this too! (and I got on a the pre-order list for the 1914 reprint).
North Africa was my first choice, but I guess it depends on the kind of game they’re going for. If it’s like the conventional A&A games (classic, 1941, 1942, Global, etc.) then I think North Africa is a fun way to go. Taking Tunis serving as the Axis “capital”, and Cairo as the Allies “capital”, or something like that.
If it’s going to be more like Guadalcanal, Bulge, and D-Day though, I think a Stalingrad or Market Garden would have been the better approach. But curious to see what it’s like.
North Africa is so interesting too. Do you do a pre-US entry into the war game, or post? I assume post, but it’s almost two distinctly different games whichever way you go!
