@General:
Moscow first and then deal with the rest of world.
Yes, a firm goal is good but timing is important too. Is Germany best off attacking turn 1, turn 2 or turn 4 etc…. Is it wise to attack early before the enemy is prepared, or should you wait and build up your forces to be overwhelming before you start the war… Germany is weak in turn 1 but gain more and more power when it grabs France and all the pro neutrals. Besides Germany lose the 5 IPC trade NO when he attack Russia, so its a lot of math involved in this calculation, its not enough with pure fighting spirit and go for it go go go
Likewise in the real world, Germany was weak in 1938, but stole the Tzchecoslovakian tanks and got strong enough to take France, then stole the French tanks and artillery and build up strong enough to take Russia etc etc …but no… that failed, they had enough firing power yes, but lacked oil and gas to move the panzers. So what if Germany grabbed the Middle East oil fields before the attack on Russia…what then …uh …
A successful attack on Russia should be launched in may, at the start of the campaign season, and not one week before it start to snow, like Hitler did. But that year it was so bad weather it had been raining all spring and summer, so Poland did not get hard surface until august, and then it was too late for a rational attack. And that is the reason that Hitler let one of his panzer divisions drive trough Jugoslavia and Greece, they could not be used in Russia before august anyway, so why not put them to good use in the Balkans meantime…
But after taking Greece and Crete, the rational way would be to continue through Turkey and grab the oil fields in the Middle East, as Rommel suggested. Then North Africa and Middle East would be Axis held, and we know what that means gamewise.
But then the attack on Russia had to be next year, and Hitler was not a very prudent man, so there we go. But if Germany had a rational leader in 1941, they would not have attacked Russia before 1942. Russia had been spending 60 % of the GDP on military burden since 1935 and had flattened the line, but Germany was building up successfully, and went from noting in 1933 to a peak of 40 % of GDP on military burden just before the attack on Russia in 1941. If Germany had patience to attack in 1942 or 43 then they had peaked with 60 % and total war mobilization, and get unlimited oil supply from the Middle East, and a start line close to the Russian oilfields in Caucasus, then they had a better chance to win.
Now take this to the game. Germany take Turkey and the Middle East turn 3 and 4 and get a nice IPC NO, and every turn keep the 5 IPC trade NO too, and 4 turns to build up the army and factories close to Russia. Is that enough to kill Russia or is it a losing strategy …uh…
