"There will be an expansion, it will be well-developed and lengthy, I won't make people wait for an answer for two hours or suddenly disappear into the astral plane, and I won't finish it before all players want it to" -- of course, I won't be able to do that.
And that's not very realistic in general. The only role-playing game, as far as I remember, that reached a logical conclusion (without forcing or anything else) was divided into modules (which were themselves divided into sessions) and was run by a GM for five years. Trying to conduct a long expedition in one go is exhausting. Either you need to break a long storyline into chapters, or make the storylines themselves shorter.
But if everyone needs an expansion, and there's no one to make it -- I'm ready to take the post.
I probably wouldn't mind playing either. I myself had ideas for running games, but I doubt I'll find the strength or time. And I would run it on Discord anyway, not here. So, go for it. If you need any advice on mechanics, feel free to ask.
