I just picked up this game from my local hobby store after watching Marco Arnaudo's glowing review. I've only played a few practice turns so far, but I'm really digging it and am eager to get it on my table.
As its subtitle indicates, thee game covers the "Soviet Attack at Tolvajärvi, Finland, December 8-12, 1939".
One thing I look for in wargames are mechanisms that represent the historical factors that led to one side's victory or defeat. To me, that's not "chrome", but the whole reason to play the game. At the same time, I prefer a certain degree of elegance. From my cursory examination of the game, Red Winter seems to have that in spades: ski infantry (whose lower MP cost across frozen lakes makes it easier for them to conduct assaults), night raids, bonfires, losses from sub-zero weather, even bonuses against Soviets on the frozen lake because their uniform color makes them easier targets!
And hoo-boy, those are some nice big counters too, and a gorgeous map!
