In my opinion the key to victory with the Axis is not any rush to capitol strategy, but playing the economic game.
Rush Russia and make him put everything in Moscow, get Caucasus/Middle East/Stalingrad.
If you succesfully get Novgorod, Volgograd, Caucasus and let’s say 2 out of 3 middle east you’re getting: 24 IPCs out of NOs alone, around 20 IPCs in Russian territories, plus Germany’s base 45 IPCs you get almost 90 IPCs.
Meanwhile Japan should get 60 IPCs with a conservative strategy, can even achieve 70.
This means Axis is scoring 160IPCs/turn (I’m purposely ignoring Italy)
vs
USA = 70
UK = 35
UKP = 2 IPCs (yeah, 2)
Anzac = 15
China = ?
Russia = 20ish (in the event that they took all african territories but you took back Iraq)
