Sburb is a game.
It needed creators, unless you think that it arose out of its own informational paradox, which is a concept that has problems of its own.
But let's start at this question: Who would create a game like this?
I take the name of Skaianet Laboratories and imagine a world in which it is the company that creates this game that ends worlds to create universes. I create characters in that world and let them speak.
What they tell me is that they are doing it because Lord English eats universes and this was the only thing they could find that created universes.
As to why the game is structured like it is, meteors and all? I probe further, and their morality looks like someone decided that Social Darwinism, along with a smattering of meritocracy and Buddhist practices, were perfectly good principles upon which to base a philosophy.
But it's used to defend their point, that the meteors are needed to prevent everyone from entering the medium and passing information to people who Enter after them; it's supposed to be a test of ingenuity. Just like the Frog Temple, and the coded messages upon its faces, is a test of sentience, to see if the species they want to call up has intellectual resources enough to comprehend the game that will be played.
They call this a company religion, now. Because it's too hard to control independent multiple-god-tiers without hitching their souls to fanaticism.
The characters in question hail from Sburb Patch Notes, which is linked to in my signature.
