there was a Historical version of Revised online for tournaments or something.
in that version they also had rules for adding Italy, to make 6 players.
also the turn order became…
in the 1st round………
Russia, then Both Axis players (Also Italy if played) taking there turn together as one (Each phase done together),
then US & UK also taking there turn together
every round after……… the Axis (together), then the Allies (Together).
very interesting way to play. unfortunately i never got to play this version so i dont know how well it worked. And I dont know how it would work for 1942.
I remember When they added Italy they made Germany itself worth 20 IPC’s, Italy started with 12 and controlled Southern Europe (which was split into Italy & S. Europe), Balkans, Algieria. there were other changes to the map as well.
