I've been saving each turn so I can easily go back and try some different things. I will probably eventually go back and pretend that I won the Battle of Britain and see what happens if Germany commits to an "England First" strategy. For now, we're following a more or less historical track where the Battle of Britain was attempted, but lost, and the mauled Luftwaffe had to be rebuilt.
I'm currently at turn 16 (late December, 1940) and the Italians have been pushed back far enough that the Afrika Korps event triggered. Historically, it would be formed on turn 17 and start arriving around turn 19. This is pretty much when it should contact the enemy, so I think I'm good here. With dice rolls its conceivable the event could fire later on other playtests, anyway. This has played out over multiple playtests so I'm pretty happy with it.
In Europe, I have the Romanians, Hungarians, and Bulgarians advancing into Greece. Yugoslavia has just "turned" Axis, though in the events there's a strong likelihood that the historical path will be chosen and they'll revert Allied soon. There is the possibility I'll catch a break, however...
I'm only a few turns away from Barbarossa (25 is the earliest I can launch it) and I'm not nearly as strong as I was last play through. On the other hand, infantry are far better units now so perhaps it will balance out. I've prioritized researching panzergrenadiers as they should prove immensely useful in Russia now that they are excellent street fighters.
I've discovered a random bug that I can't figure out - my Romanian Bomber does not show the health bar even though I haven't deactivated it in rules. It's one of the 62 extra units, but none of the others (so far) have this issue. It's a little perplexing but we'll see if it keeps up throughout the playtest as the art changes.
All in all - the changes made after the last playtest have made this a better game. The convoys work thanks to Prof. Garfield, which means that Bomber Command is a real threat, and I have to spread resource carefully.
While I am going to look into balance on the Battle of Britain given I, the designer, deliberately tried to win it this round, I think for the most part, this is going to be a game of choices and I don't think you'll be able to just cruise to victory.
