I'm going to talk about three world seeds that are somewhat based in the Bible, and are somewhat or quite a lot SF. One is not mine.
I am of the view that a lot of Christians don't get into RPG's, but it might be possible to sway them. Also, we need good worlds for everyone.
One idea of a ways back was based on Lot and Sodom. "Lot" is the keeper of the Main Planetary Gun A. These are huge railguns going dozens of miles deep into the planetary crust, and there are three (A,B, and C) to cover the sky. As part of the job, he also maintains the Honor Memorial for the Fleet that went into space to fight the alien menace and never came back, both it and the aliens are gone it seems.
What happened is the Fleet of cyborged humans left, fought, and were on their way back when they got informed that the PG's were locking them up. It seems that the civilian types had a strong difference of opinion with the military types on moral duties. The civilians were glad to send the military off to save them, but when the mil guys got back, and wanted to vote and stuff, well, their old-fashioned notions of duty and honor would be repressive of the New Acadia.
So they were told to buzz off at the point of a really large shotgun. And the new masters of Acadia told everyone 'they dissappeared, so sad.'
Well, in the centuries since then, Acadia has become a place where 'honor' and 'duty' are not even in the dictionary, much less people's lives. And B and C PG's are down. So the Fleet has found itself running up against resource limits in the outer system, and it really needs the access to the local sun to refuel its fusion reactors.
The Fleet sneaks up on the planet on the B and C side, and lands two cyborg soldiers to investigate in New Acadia's capital. They find the place is more horrible than they can imagine. Only robot servitors keep the society functioning, and people from starving. The possibility of making a treaty with people who don't seem to understand the concept of 'word of honor' and laugh merrily at 'honesty' is nil. But they do find one good guy.
And they tell him that its time to leave. They take him and his family to the shuttle and into orbit. And then the KE weapons arrive and pummel the last PG into nonoperability which does a lot of damage to the capital, but it also makes it so that the New Acadians can't backshoot the space based civilization.
I've of course, written on this before, although a bit differently.

"Kings" on NBC? did not last long, but it was an interesting idea. An alternate reality with a modern tech or slightly further ahead, but with Kings instead of Republics and Democracies.
They seemed to say they were going to follow the Bible and other texts and be creative. It could have been good.
Unfortunately, they chose to make David a peace activist type guy. They have him as a soldier toss a grenade to destroy a Goliath tank. That's cool. That's pretty clever. But he does it by accident. Um. Perhaps I'm wrong, but it seems fairly clear that David deliberately set out to kill Goliath of Gath, that he had a plan, and he worked it. He had faith in God's care, and that God wanted him out there, and he had his skill with a sling, and he had past experiences killing dangerous creatures. How many of us have killed a lion and a bear? With primitive weaponry? Right. Not really a peace activist. And that perspective they had kinda killed it is my guess, or was one of the major factors.
Still, take away the unbiblical stuff, make it a bloodthirsty world of Kings and you could definitely have something. David is a complicated guy, and he has a lot of adventures, and sometimes his solutions and responses are surprising.
=============
I was reading in Genesis about the Tower of Babel. The Bible talks about how the people gathered together to make a name for themselves, and to avoid being scattered in the Earth. And God comes down, and sees this, and that they all have one language, and He says that nothing will be restrained from them. And so He confuses their tongues, and we have the birth of the major language groups.
The ideas behind Vinge's Singularity are very echoing of Christian ideas. The Singularity, in short, is the idea that the rate of technological advance is speeding up, faster and faster. Ten years of research gets compressed into a year, and then a month. Along the way, some form of superhumanity, of superbrains, becomes possible. And it reaches the point where any logically non-contradictory goal is achievable.
You can't say 'make me the prettiest person on the planet' because someone else will be doing likewise. You can't say 'make me green and orange in the same color' because that doesn't make sense. But you can say 'terraform Mars as my personal garden'.
In other words, nothing will be restrained from them.
And at this point, an angel comes down, and the trillions and trillions of lines of computer code that make up this society, are suddenly broken up into ten differing operating systems. To keep it more mundane, say an alien spaceship comes by. Their goal is to slow humans down enough that Humanity won't just explode out, and remake the galaxy in its image. They want humans to learn a little wisdom first. And they figure having ten human civs strive against each other might teach them a little sense. And yes, that OS breaker would have to be invented by the League of Totally Awesomely Insanely Powerful Aliens in order to stop the Humans from blowing on it, and wishing it away.
Yes, the goal 'turn the Milky Way Galaxy into an advertisement by moving the stars to make a cartoon of Milky Way candy bars' is possible.
Now the question becomes where do you put your verser in this world. After all, everyone has the ability to move stars using pocket change. Even versers like the Alchemist might be underpowered to cope on equal terms anyways. One solution is to make this world a moral judgement world.
Verser arrives on Observing Alien Starship. The Alien Superbrains tell him that Humanity is about to go through its Singularity. And they've chosen him as Humanity's Advocate. He's the Defense Attorney for Earth. Some of the more stringent superbrains favor vaping Earth now. Others favor altering the bias a la SM Stirling to make tech above a certain level impossible...
As Earth's Secret Attorney, he has to go to Earth,observe, make arguements for his case, and try to defend Earth from preemptive annihilation. And of course, he's going to run into things that make him wonder if the stringent aliens are correct. He's going to meet humans who are as despicable as the worst alien nightmare could imagine.
