Is it important to convert every enemy hex
Yes, otherwise Soviet units may reconstitute in those areas and cause you a bigger headache than you need.
... enemy zones may appear in areas you have converted due to partisan activities.
No Partizans in D21 until 1944. I won't tell you exactly when as that would spoil the surprise.
is this game anything like wite where all the russians run at full speed?
The Soviet side in D21 will not run. For some back history on the scenario, initially the Soviet side was set to keep coming at you at all times. This was felt to be a good representation of Soviet doctrine. However, most players considered it too easy to defeat the Soviets with this setup. So we found several points in history where the Soviets tried to build defensive lines and then set the PO to react to the situation on the map. Most players have liked this, so we have continued to work with and improve it.
Not sure if anyone has ever finished it though.....
I've only seen the end files from two that I finished and one from 'Patrick' if I remember correctly. The first one that I finished was the first full playtest and I actually didn't finish as the Soviets were in Berlin in late '42. The other one was 3-4 years ago and after the '43 Axis offensive I had crippled the Soviets so bad that I eventually advanced to the Urals and by turn 405 there were only a few Soviet units on the map. This guy Patrick managed to wipe the Soviets off the map by around turn 250, no reason to 'finish' at that point, he won.
I believe that most plays of this scenario end before the finish, as either the player has done well enough to realise there is no point in continuing, or at some point they notice they have made a blunder that they don't wish to attempt to recover from so they quit. Those situations seem fine to me, the ones that bother me are when a player plays 40-50 turns, captures Moscow and/or Leningrad, and declares themselves the winner.
Anybody can win Barbarossa, thats easy.
