[Griefbringer]

I have also been playing a number of games set in Poland in 1939. There are a whole bunch of interesting scenarios in game for that.

For historical actions, there is also the Winter War between Finland and USSR, starting at the end of November 1939. Though while being Finnish, I have not been too interested about trying to game this conflict lately.

I have also played some games set in the Japanese invasion of China in the late 30's.

And I have considered playing some Spanish civil war battles, but never managed to actually complete one of those...
