The Axis need to not move slow! Turn one and even two have the allies stuck in predictable positions. Exploit it or any mistakes they have made.
Example. With Japan dont build your major factory some place close and safe like Manchuria. Plan on someplace far away close to your enemies and difficult for the allies to get to.
With Germany make the Brits cower for fear of Sealion. They screw the pooch and build in South Africa turn 1, leave or loose that transport in Canada or take that tac bomber into the Med make tham pay and own England.
If Russia pushes hem 18inf on Japan kill them. Seven or eight land units and your air force open Siberia.
The Axis have the iniative. The Allies can loose India and England if they mess anything up. Australia if Japan is interested.
It just takes longer to figure out where and when the Allies aren’t strong.
Example. If their navy lives Italy can take Egypt. Assuming England lives they can build a couple mech and a tank a turn is south africa. Is that worth fighting? Maybe if you can isolate and kill them. Moving your eight or so units from Egypt east sure pressures the Russians on another front while the Brits are just driving through the sand.
I do admit it is difficult to be the Axis. First time i ed the Russian infantry stack i thought i had won the game. Oops. Just dont give up yet. Easy is not fun.
