I’m not sure what successful Allied players do … though it definitely includes greater investment in the Pacific.
I’m playing another game right now as Allies where (again) I’ve pushed hard at Europe but I might lose a sixth VC in the Pacific before I can sack Berlin or Rome. And that’s with a reasonably strong UK helping and 3 minor ICs.
I understand why KJF is promoted, but if all 3 Axis powers invade Russia early (without bothering with Sea Lion), Axis wins in Europe before Tokyo falls. At least, I’ve had Axis success following that strategy.
