there is only an indirect link.
a 1 (or 0) ipc terr cant get a factory, and thus cant produce anything
a 2 ipc terr cant get a major factory, an is thus limited to 3 units produced
a 3 or more terr can build a major IC an is limited to 10 units produced (this is only a limitation for eastern and central USA with production of 12 and 20 ipcs)
And submarines / fighters on carriers can do 2 damage under the new Alpha 3 convoy rules. (Under the old, Submarines could do up to 2 to each enemy nation bordering the convoy zone.)
For Russia …… Slash and burn, move the factory back one spot, then there is nothing for the Axis to Capture.
For China … destroyed!!! anything would have to be rebuild.
For Germany & Japan …damaged, pay for repairs this would also be the fate of the rest of the Axis and Allied Industrial Complexes
This is just my thoughts on the subject
Ozteas 1941 is well reviewed. If you’re comfortable with some players being at peace at the start, that is also worth a look. Starts like round 3 of 1940.
Although if you prefer the simplicity of everyone fighting right away, go to g42!
