In the end, it came. On August 11th 2021 — with the lengthy standard-issue delay one hopes to be a warrant of quality — came it did, on a file of no less than 113 MB.

I have played through circa 10% of the game, maybe 5% would be more precise.
Early impressions are, it's less complicated to hit a single home run than two in a row... but I look forward for the game to change my mind*.

The game did indeed change my mind. It isn't without annoying downsides, but most of these can be seen as tangential, and it is a worthy follow-up to the first AX, which you should play before this because there's some logical order to that, and, more important, because it remains the better game between the two, and not by a particularly narrow margin.
