my japan parties like a rockstar. fortress anzac, kind of makes the battle for hawaii easier more or less. kind of depends what anzac is making. ie 2 inf 1 fighter a round or what. usually shut that bonus down so it depends. Hell I did go africa/middle east once and germany did his russian thing. When anzac is not an aggressor it usually frees up some ships for expansion, got to match usa’s income.
plus usually usa need’s anzac ships to defend against japan’s attack… plus if you are sitting at hawaii what ends up happening is mexican standoff instead of the allies progressing in the pacific, things just come to a standstill.
It is up to germany / italy to advance. When russia just builds inf, it is easy to postpone russia for 3-4 turns since pacific is a stalemate and blitz africa a bit and screw russia out of money.
