In my opinion, the DH developers should not waste their time on alternate timeline fantasy (or players who want to conquer the world as Guatemala!) when there is so much work that can be done on the historical WWII era.
One improvement that would greatly help gameplay and make DH equivalent to AoD's gameplay mechanics in some respects would be a better logistical system. As it is now it just feels too much like an arcade game as the panzers blitzkrieg through the Urals and beyond.... Even something as simple(??) as tweaking the base province ESE and exporting the setting to misc.txt as AoD does would I think create a much different game.
(or allow province ESE values to be set as a constant in the provinces.csv file)
