Haven't actually tried any of the men of war series, how do they play for those who have? And as to the question on the GA Sachys, I think that had the Axis powers won, the U.S. of America would have been very much on the defensive over the next decade in a cold war with the European powers on the one side and Asian powers on the other. Probably would have allied with the South American countries for mutual protection, while Europe would have largely fallen into Germany's control.
Ever read The Man in the High Castle? I like other Philip K. Dick novels but somehow missed this one where it is written from that alternative history with the Axis powers winning WW2. Axis of Time and Clash of Eagles are two others on a alternative history book list
that immediately looked interesting on this topic.
