@Ominous I think the very nature of large, multi paragraph posts (presumably with actions beyond fluff within them) doesn’t quite lend itself to the kind of flowing granular exchange most RP interaction needs.
In my experience with novella, at least in the recent years, what happens is people don’t want to wait another week for their turn, so they pack as much as they possibly can into a post, interacting with other characters and then presuming vague responses, so you get a kind of backed up out-of-order situation. If people play on the safer side, they opt to do a bunch of thought-posing, which I think is actually something that at least part of the crowd appreciates or is pleased with, in style of “Yay someone is thinking about my character”.
I’m unsure how it was decades ago, but at least presently, there is no controlling a portion of the scene. JUST your character. I got pretty severe responses when I indicated another character may be able to see some headlights or something entirely innocent like that, something to just move the scene along.
I’m actually unaware of any RP setting in which you are basically writing a book together and you aren’t controlling your character. This is the first I’ve heard of it. @Faraday is Storium something like that?
