@Cow:
The Europe half sucks for me, the skirmishes only occur between Italy and UK, the rest is a big stack moving toward Russia, maybe a few infantry blockers here n there to fight, but it is a one way movement for the most part which is stupid.
Nobody ever came with a stacking rule and/or some kind of enlistment track limiting infantry and tanks that can be built (taking into account relative labor force of each country)? Those two simple house rules could improve the strategic feeling and flow of the game.
