It kind of makes Astrid and Co. and how they got to space the "real" story of KG.
I had long suspected (at least since the scene of young Kane and Olivia in the temple - Ep7) that “being sent into space” would be the canon ending.We later learned that each side (Dom players and Sub players) would get their own canon ending (among other endings that aren't), but there would be another, true canon ending (according to Tess herself). And there was little doubt as to what it would actually be. Further events have only confirmed this.
We know that Tess wrote the entire history of her game universe (in her own words) long before Karlsson's Gambit, the events of which, if I remember correctly, in “manuscript form” take up only about 10% of the entirety of the written global history. And relatively recently, we learned in
Q&A (in the answer regarding Veronica's identity) that, at least in Tess's mind, there are about 7 different games related to each other.
In my entire giant lore of seven connected games in my head, Veronica Karlsson is a giant figure that impacts way beyond KG.
A third game (written by Tess herself) is planned after Karlsson's Gambit is finished, and not much is known about it yet, except that its events (if I remember correctly), also take place in space, in the distant future.
So it looks like “QA” is just one of these possible 7 games whose events could take place in this game universe and
KG is
exactly the foundation and linchpin for future games. You can delay the agony of the Earth, but you can hardly save it permanently...Even if it succeeds, in any case, the world will no longer be what it was before the Great Collapse. And so it is necessary to explore new worlds, expanding the habitat of mankind...So the “space ending” with the colonists always seemed pretty logical to me under the circumstances.
