Ironic, I tried that myself in Civ2. Must come naturally to a few.
except I did it on Prince level, and with many variations in the rules.
2 I can think up on the top of my head was 5 production rows (1 half build time, IE XL production), and I changed terrain/resources a bit.
I also added 50% to the attack rating of all ships, and effectively quartered the cost of settlers and engineers.
You have to sell everything in your other cities, except Amsterdam which is taken on the first turn, and you have to bum the Allies for as much tech as possible. If you can hold the nazis off long enough, try and airlift your population units to Tehran asap. Use all excess $$ for building as often as possible so the Nazis won't take much of it when they capture budapest or stockholm. Then it was an eternal struggle to hold off the Soviets.
Fun
