Its as if the entire plan for operation barbarossa was Hitler saying "Moscow - attack" and then watched to see what happened.
Thats pretty much what happened in real life.
Hitler was "involved" in the planning of the attack, but not much more than setting a broaaaad goal.
The actual plans were left to generals and subordinates. If you play with the AI controlling everything, and just play as the Furher (a president of a democracy would be much worse, youd have to argue with congress before even being able to produce an artillery bde, gotta get that money from the senate defense commitee

) you really wont have much to do.
As supreme leader, I say to my Chief of Staff, I want to conquer the USSR. He then turns to his subordinates and says, I want you to brief me on the readiness of our armies and begin to think tank a strategy, those subordinates then go on down the line giving more and more specific orders as you get down to the squad or platoon level.
Hitler never had any idea what a Lt. was telling his Sgts to tell their Pvts. Nor was he ever involved in those kind of tactical or strategic descisions.
