Bits and pieces, sure. TFA:R was driven by a single core idea, so there wasn’t a great deal of outside input. (I’m sure I’m just forgetting things about it at this point, to be fair.) TLJ was more trial and error, with poppasketti and I cross-pollinating quite a bit.
In both cases, I feel that the projects benefitted immensely from having input provided by members throughout. For the prequels, I was mostly working with an established textual history, sort of like the brothers Grimm or something.
As always, I just want these to exist and am super thankful for any and all help in making them. That being said, I’m about ready to see it all finished up, with ROTJ and TROS being the final pieces to lay into place.
