Adventure Plots Up For Grabs Thread 5: So There's This Guy

A great disaster has befallen the Earth, be it meteors from a regular SBURB game or something original. In any case, most of the planet's surface has become unlivable and most of humanity was wiped out. However, one group of scientists who had been studying some mysterious technology found in a temple in the shape of a frog managed to decode the hieroglyphs on the temple walls and discovered the coming apocalypse years before it happened. Knowing that if they tried to tell the world, it would only cause panic or be dismissed as another end-of-the-world hoax, the scientists decided to quietly continue studying the technology and develop a way to ensure humanity's survival. They only managed to devise a way to protect an area the size of a small city before the disaster hit, so they gathered up their families and whoever would listen and bunkered down to wait out the apocalypse.

Several centuries later, humanity is still nowhere near where it was before in terms of population, but technology has advanced in leaps and bounds. The once-arid land has been converted to farmland to sustain the few scattered yet sizeable colonies spread throughout the world. Teleporters and other technological marvels are as commonplace as cell phones; visiting your grandma on the other side of the planet is as easy as walking down the street. The people of post-apocalyptic Earth live well-fed, comfortable lives. And then the second disaster hits, and there's no hiding from this one.

Earth's population is already much smaller than it was when the first apocalypse happened. This time, humanity will be totally wiped out. The only way to save the world this time is with something the descendants of the original scientists have been sitting on for a while. A game.

Not just any SBURB game, though. Over the centuries of studying and tinkering with the game's code, they discovered a way to alter the game's structure. (Or just send them to a *super unique* session. SBURB planets don't exist before the kids enter and paradoxically have always existed after, I figure the game session entry works on a similar principle.) Rather than players entering one-by-one, entire cities are transported into the game at once. And rather than each successful entry having its own planet in the Medium, all of the cities are on the same planet, which is lush, fertile, and able to sustain several cities in terms of food production.

OPTIONAL:
- There may or may not be a Skaia or frog breeding. If not, the inhabitants of the new planet may decide that this one's as good as any. End goal changes from "create a new universe" to "explore and defend our new home".
- Since time immemorial, the Horrorterrors have watched SBURB session after SBURB session be created, played, and eventually failed by various alien races, occasionally broken up by the odd success. Then this new, weird session comes along and the Horrorterrors get curious...
- For extra fun, throw in some trolls and/or fanraces. Every alien species can have its own planet in the Medium.
