I bought the game and got to it as Germany obviously.
Everything initially went my way (good old Hitler playing the big game), but something went wrong with the Czechs and war erupted when I wasn't prepared for it (I had my armies all over the place). A couple of other things also went wrong and I was essentially losing the game even before it began... I was surprised how fast it could turn on you. In HOI a war with the Czechs was no problem. So I reloaded an autosave and made preperations for war, this time it didn't happen, and I split with Hungary.
The war with Poland came and I was doing great, catching their only HQ division in a pocket with a large portion of their troops. But then it happened, the thing I dreaded the most... France attacked!

Can you believe it? They made an offensive into Freiburg, 23 divisions against my measly 3... Rats! My men fell back before the onslaught as I scrambled to fransfer troops from the north down to meet it, but it wasn't going to be enough, my armies were in Poland (where I was suddenly meeting very stiff resistance near Warsaw). Even worse I had the Altmark incident there, gearing the English to become more active.
Then I planned the downfall of France, it was going to be a very elaborate plan. I had only 3 divions in Friedrichshaven, but plenty behind it and to north. I lured the French to continue the attack, and they fell for it, attacking the weak forces in Friedrichshaven which fell back at once. Now was the time to attack Freiburg.

I sent 3 tankdivision to attack Freiburg assisted by an HQ army (HQ division, some infantry and some motorized), the few french forces fled fast and my tanks arrived early. The French now saw their predicament and tried of all their power to attack my Panzerkorps in Freiburg with all their had, no less than 32 divisions attacked me, but I intereupted the attack from Friedrichshaven by attcking that with the encircling forces. The plan was not to win that battle but to save my tanks until help arrived.

My planes that had been transferred from Poland were flying Interdiction all the time and helped the tanks greatly. Finally the last French broke off the attack and I 23 divisions (including their sole tank division as well as half their Mountaineers) in the bag. France gave up at that point planning their defence alogn the Maginot line. But sadly I couldn't jump at the advantage as my forces were still in Poland or on their way. When they arrived it was winter and I settled down to upgrade my troops and wait for spring.

Sadly Fall Weserübung happened with me having no troops ready so I had to ignore Scandinavia.

My worst setback came at sea... My mighty fleet lead by Scharnhorst and all my heavy cruisers, supported by all my light cruisers and all my modern destroyers entered a battle out by Rockall. They won it and sunk a few small French ships, but then big brother entered the game. A mighty fleet of BBs and BCs attacked my fleet and in several engagements (while I was furiously trying to retreat) annihilated it. Now I had only one destroyer squadron, Bismarck and the two old BCs in the east. Even my submarines were getting blasted out of the water, sinking a few transports and escorts.
In my fury I planned masses of new submarines, and the next time I took to the sea Dönitz gave an English ASW patrol a good licking, sinking a CL and a DD.

This is my position now. Precarious at sea and strong at land (though the French are gearing up after their disasterous defeat) and fearful of the Soviets (who have just won the Winter War after initial losses of land to the Finns). Only Hungary is my ally, but Italy is coming around and so is Rumania and Bulgaria. I need to defeat France fast...
