I’ve owned AAA since the first print run, but is has seen considerably less table time than 42.2.
Italy and China I think are more of a nuisance to play than really fun, and without NO Italy isn’t going anywhere anyway. And this might be minor, but the IC in India in 42.2 makes for far more interesting play in the Pacific and KJF is actually not completely outmatched by KGF.
And out of interest
It seems that at least one scenario of AA50 is mostly balanced, and 1942 is heavily Axis-favored.
Which is that, 42 with NO? Because it can’t be any of the 41s, without NO Germany is dead, with NO there is no stopping Japan.
