"Merge finances" aka combine the family jewels.

And as the minerals are depleted, the island begins to sink until it has been completely depleted and it settles on the surface, crushing whatever lies below.
If the citizens care enough to ensure it lands in a usable state, and the city has developed a diverse enough economy, it may survive and go on operating as a regular city.
Most would probably be abandoned once depleted, leaving behind large mineshafts and abandoned buildings for nature or squatters to reclaim, which could make for fun dungeons.
This assumes anything would evolve in such an inhospitable environment. If it's cold and oxygen is thin, it'd likely be as barren as mountain tops.
I'd suspect they would perhaps be a popular place for large flying creatures who might like to make nests there in safety and use them as resting locations during long migrations
They'd probably also attract humans and their ilk who wish to capitalize on the islands' natural defenses as well. Though this would obviously come at a cost of seclusion. Goods would be difficult to transport and would probably cost more than in a city on the surface.
I'd imagine they might still find settling up there worthwhile to mine whatever unique materials these islands hold. Perhaps the islands are composed of rare magical minerals that cause them to float. Minerals that would probably fetch a high price.
Just don't connect smart TVs to the internet. Get something cheap like a raspberry pi + wireless mouse/keyboard or an android TV box for the same functionality. (More functionality, actually)
I got one as a gift. So dumb. Just what a I need in mug: IoT and a charger! /s Plus, I can just microwave a normal mug to heat it back up, but not this. And forget about the dishwasher.
...except now that I've used it. It's pretty fucking nice not having to go over to the microwave when I inevitably forget about my drink. And if I use the charger as a coaster. That battery is always topped up. So, I understand its appeal.
Tl;dr: It's dumb, but it's also actually quite nice. I certainly wouldn't buy myself one, but I enjoy using mine.
My '21 Malibu had it out of the box. I can't speak for Car Play, but wireless Android Auto is 95% flawless. There's that 5% where I get in and the phone won't connect automatically. But I think it's an issue on the phone side. I have to unlock the phone then it kicks in.
I don't really get to play much these days. But I'm currently reading Fléaux! to help me flesh out the Black Sword Hack campaign I'm planning.
I'd like to add the OGL they were pushing would have effectively allowed them to steal homebrew and 3rd party content. They'd reserve the right to resell this content as their own or make it disappear altogether.
This would include supplements and adventures, of course, but the way it was worded, it would even include blogs and YouTube videos, etc.
Of course this isn't a unique situation (Meta has done this forever, for example)
You could totally do something TaskMaster style.
Wow, that is a substantial update! Looks good!
As a general rule, at least in my experience, players don't read. Unless they request a pdf, I wouldn't bother.
Personally, I would bring it up in Session 0 without getting too specific, just the big changes you plan to impose. Then warning players if they make character build choices that would be impacted that you're not going to use RAW.
Makes sense if there's one nation that dominates economically and/or diplomatically. Like English today, IRL.
Though, if one group does not have such a strong influence, you'd probably end up with something like the "Lingua Franca," a mix of multiple languages spoken by the most relevant nations (IRL, in Renaissance Western Europe that was a mix of Italian, Greek, Arabic, Turkish, etc.)
So Common may not be a proper language at all, but instead be a creole/pidgin of all the other big ones. So characters hearing a language they do not speak might still catch words here and there allowing them to decipher the gist of what was said. Also, Common would most likely be spoken in more metropolitan areas. A backwoods farming town may only really speak their native tongue, save for the mayor or merchants.
