@Lufftwaffe:
I have found that if the germans build gobs of infantry for the first 2-3 turns and then builds massive armies of tanks you can capture Moscow in 4-10 turns, espescially if Russia is foccused on Japan. With Japan I like to take out the american navy, capture india, and build a factory in Kwangtung. :-D
Luftwaffe, come and join the tripleA community and test your strategy in some league or friendly games online. You will see that there are more secrets to the German and Russian strategies then buying infs and tnks.
The catch of your strategy is that if you are only buying inf first turns you might lose countries and make less IPCs and come less strong against Russia that might be on the opposite stronger then it would be otherwise. Also if you are buying no air, the US/UK need not buy that much ships to cover their trannies and will come to Europe earlier. Do you do Anglo-Egypt R1? And yes, you will find Russia dealing with Germany during first rounds most of the games.
