@master4709:

SS, that is an interesting idea with naval and air bases. What made you decide to not be able to purchase any during the game and limit 3 movement to non-combat only? Can they still be damaged by SBR?

The idea was for strategy and forcing the 1 extra turn for combat. Im not a big fan of bases but everybody else likes them. Yes the Air and Naval bases can be SBRed. Airbases still can scramble 3 planes for naval battles. Plus get the +1 move.

Are railways needed for a map this big for the USA and USSR?

For me we use the railway for Russia, US and Burma road. 2 Inf or 1 inf 1 Art can move 2 spaces ( Russia move 3 if they get there NA ) only per turn. The railroad is marked on my map.

I think I will add the convoy zone boxes to the map.

Yes I would too. Germany needs these boxes for game more.
