what if ....
Let's say that the Germans never held off invading Russia to take care of things in Yugoslavia etc . Let's say the Germans invaded Russia at that point in time and managed to get to Moscow a few months before winter and control it . Now this game , when you take control of Moscow the capital is moved and the battle goes on .
In reality , let's say the Germans DID take control of Moscow , what would have been the consequences ? What would have been next ?
