What is J1? Japan attack non china allies in pacific?
As Japan, I once attacked allies on turn 1, no one took me seriously and I won the game by turn 4.
What about an english strategy of industrializing the middle east? Take Iraq and Iran on turn 1 and build complexes in egypt, iraq and iran. The fleet/airforce from india can sure up defense of the middle east until production is up and running. Building mechanical infantry in the middle east can help ensure india does not fall to japan or truck into russia with air support.
I had an idea for a German/Italy strategy. Japan must no go to war with US until turn 4.
Opening Move for Germany. Build a small industrial complex on the black sea in romania, 3 mechanical infantry and a sub.
The plan for Germany is basically to build mechanical infantry early and attack spain and sweeden on turn 2. Then pump Gibraltar full of mechanical infantry. This will give the Italian player breathing room in the Mediterranean. Also germany can build some transports in the black sea. Once Italy takes turkey, they have easy access to the Middle east (6 ipc) Germany can put a unit in egypt (5 ipc), italy can transport into 4 russian territories.
