@Flaviusx. I've only had to survive 4 turns - there are still 8 turns to go! Seriously though, I have always felt that the First Winter was going to be the subject of much debate, as there are only so many game mechanics that can be adjusted to simulate the unpreparedness (is that a real word?) of the Wehrmacht to deal with a winter that was worse than usual Russian winters. As in my answer to ComradeP, the mechanics being used are Morale and Unit damage. There are no additional logistics penalties other than the Motorised MP cost that increases due to the blizzard, but this applies to both sides.
I don't think Logistics were the main cause of the Wehrmacht's loss of combat power, other than their inability to supply the troops with the right clothing and lubricants. They had enough bullets, what they didn't have were machine guns that could fire the bullets in temperatures of -40C, or troops that were physically and mentally able to cope with a temperature that dropped to previously unheard of levels or deal with an enemy that was more than happy to fight in these conditions.
Everybody needs to reserve judgement until they see the 1942 summer offensive start line that I achieve,and the relative strength of the 2 Armies before deciding if the First Winter is "overpowered". There are 1 or 2 surprises in store.
AGN has lost the fewest hexes so far.
