I remember hearing that the game starts late enough in 1940 that there is UPN, that the low countries have all been invaded. But we’ll see soon enough I suppose. I really don’t think the Dutch will have their own pieces, though, if anything they’ll use another power’s pieces.
As for AAP40, I’ve seen plenty of games where China does fine. Its all on what Japan focuses on. Last game I played, yesterday actually, Japan took Australia very early but as a result China pushed them back to the coast in some areas. Of course once Australia was gone Japan started to dedicate more resources to China, which got pushed back, but China is supposed to be a purely defensive power.
