Great advice, although I was looking to have a more collaborative and less hands on approach for this, but I think I might pivot. It's been years since I've ran an RP so I gotta shake the rust off the chains.[/quote]

By that, do you mean you'd want Players to come up with the plot elements, design antagonist characters, or something else along those lines? If that's the case, you could make a list of things you'd want Player input on, or just ask them the same questions I pointed out before--"What do you want to see in this RP?" basically, but maybe more specific.

Do you have a Character Sheet drafted yet? For a collaborative plot, knowing what kind of characters you'd be looking at would probably help a lot. Like I mentioned before, getting characters to tie their backstories to each other or to other elements of the RP has, in my experienced, helped a lot.
