Gonna be honest. Picked New Gibson for my latest character concept largely because it had room for improvisation. Seemed like an industrial working class melting pot, which is what I was looking for, where I would be free to define my character's ethnic/cultural background how I wanted -- something akin to the Belters from the expanse. Different ethnic groups forced into an inhospitable melting pot, with each arcology having its own ethnic/cultural background that turns into a cultural slurry as travel from dome to dome, arcology to arcology, gets easier.
I didn't want to get shoehorned into a particular cultural background as so many other planets are in lore. Since the population of New Gibson lives in disconnected hermetically sealed domes separated by miles of untraversable ice sheets, it does not make sense for them to be culturally and ethnically homogeneous as they have now been rewritten to be.
This isn't anyone's fault, but I'm a little miffed because my concept has been retconned for me and now I'm in the position of either trashing the character and/or doing a severe retcon to make them come from a different planet. In short, pretty disappointed with the changes. I feel like nuance could have been added to the existing lore without retconning pretty much the entire cultural and historical landscape of the planet.
Regardless of all that, the lore as it is now written has issues. Before it was a bit sparse, but internally consistent.
Now we now have an almost entirely Scandinavian/Swedish/Filipino planet which has an inexplicably English name, and its capital city has an inexplicably Chinese name.
The information in the introductory paragraph clashes with the information added under the "Founding" section. The introductory paragraph seems to clearly suggest that the effort to colonize New Gibson was lead by Biesel who made it a colony, in order to consolidate economic and industrial power within the Tau Ceti system. If that's true, how is it that refugee populations from Earth ended up being the ones to settle it as per the stuff that was added? That doesn't make sense. The new stuff is not logically consistent with the old stuff.
So, all in all, I think it made it messier than it was before and I feel like the Scandinavian/Swedish/Filipino stuff seems shoehorned in when compared to the stuff that was already there.
I think you really have three options:
Retcon basically all the earlier lore (capital city, the first speaker's name, Biesel being the one to colonize it, etc etc). Make it actually fit the cultural background that was recently shoehorned in. New Gibson can become New Gothenburg. Speaker Xin Hengsha can become Speaker Bjørn Bjørnson. For the record, I think this is the least interesting option. Stapling a real-world ethnicity onto the planet doesn't really make it more interesting.
Make it the melting pot that, in my opinion, it should have been -- with different ethnic/cultural groups immigrating at different points in its history after Biesel settled it and founding their own domes/arcologies. Then the planet starts to become a cultural melting pot as a subterranean rail system is constructed to connect all of these previously disconnected, culturally distinct populations. Kind of like a galapagos islands of human cultures... in space.
Leave the stuff you added, but walk it back a bit. Keep Scandinavian/Swedish/Filipino refugee arrival as a historical event that raised the planet's population, but make it less central to the planet's founding, which, after all, the introductory paragraph very clearly suggests was initiated by existing populations in the Tau Ceti system.
I really hope something is done to bring the new stuff into alignment with the old stuff, because as-is this is less canon and more confetti canon.
