My two cents (I've played the Polish scenarios (North), Norway South and then Sedan):
I feel like the Bf 109E is performing a bit underwhelming compared to what I would expect. No matter if it is up against the Polish and Norwegian biplanes or the French monplane fighters, the Bf 109E always gets smacked around. Almost always I need both my Bf 109E and a Bf 110C (later D) to bring down a single fighter. And while doing so the 109's take quite some strength hits (making them even weaker moving on to the next plane). Maybe the point is to overstrength them (I've bumped them to 14 now, have had them at 10 so far), I will try that for the next scenario. Still, the 109 was, apart from the Spitfire, the best fighter in Europe at that time but I don't feel it's reflected as such.
A quality of life improvement would be to add a real world clock in the top right corner when playing in a full windowed mode, just like Civ VI does. Cause much like the Civ-series, this game has a tendency to make you think "just one more turn" and boom the time flies. So it would be a nice addition along the road.

Love the consolidator hero. A very good name for it.

I think I encountered two bugs:
1. I renamed all my units, but when I started Norway South I noticed my Ju 87 had reverted back to its original name. Don't know if it happened just then, but that's when I noticed it.
2. In options for the campaign, I removed weather as a function in the game. But on the first turn of the Norway South scenario, it was raining and none of my planes could take action.
Other than that, everything works fine so far, much like the beta did. Looking forward to getting deeper into the campaign. Good work!
