so...:

1. You wrote "In a Quest, .... but someone reading after the fact has no options and treats it as a straightforward story."

But someone reading after ... after that it becomes a bit confusing. The "the fact has no option" after reading it thrice I understood where you were going with it. I would recommend changing it and that after it too a bit. Like "The audience at the time will affect the story, but someone who arrived late to the party leaves all of his rights to vote this poll and shall thereby not micker and wait for the next one."

Then after you explain in a more detail, which shortly explained is bad in an introduction, not bad as a chapter, but as the first thing your readers see... It’s bad.

One’s attention span, when going through Books and looking for something to read is short. That’s why many Stories have a short and gripping intro. It’s too kept someone committed in reading. Not gonna lie your beginning drawn me in everything after got me just lost. I still have not quite the clue where I'm going with his, I know what’s happening, but nothing more than that. If you want to write an intro, try to keep it short and dandy. So, someone of any interest could pick it up and say yeah let’s try that one.

Idea:

1. You could post everything after that as an intro chapter into the Story following up with a Prologue to go more into detail. You could then take this as a test on how the voting system is coming along. For example, my stories have polls, but nobody votes as they are not interested or lazy. So, to see if readers who follow the Story are also taking part in it. Would be the first thing to check.

2. Write after that a short entertaining World view of your Story, about the Worldbuilding you have done and what Readers can expect when trying to create something in your Story like. "It’s a Doomsday planet whrittled with sloth, dirt and corrupted grass. The air is almost unbreathable, and the Stones seem to take in parts of their environment, with some stones appearing wood like." You know like a little introduction into the worldview of a Character not a Gods perspective. As you want them to be invested into the story not, you’re writing.

3. Keep ad it. you make take stumble there and there but keep in mind something like that needs a following and inspiration. You will give out a limited number of choices, so if people write in the chat how they would have loved for a more interesting choice. Then you would see that your polls need some changing. Idea there if you create a community try to take in some rly invested people and ask them about their opinion for these poll choices and see if you can modify them to take in the view of many who will take part in this adventure.

Lastly as this was a bunch of tips with me not stopping to write... So here is todays sponsor Arechnocadia, a startup company who has recently started a writing contest/Project/Event. In which writes can take part in an interesting Setting to explore and get inspired by, while at the same time write fiction with others, which comes with the twist of it having influence on other Stories: Example "Pandora’s Box gets opened and then you see in another story how a guy on the other side of the Planet feel the earth shaking."
