I think I would require monetary compensation to write on demand like that again LOL. If you want to HIRE me to write your fanfic, fine... I'll do it for money. But otherwise, no way.
I have never given someone else a whole story idea and asked them to write it. I don't know how I would feel about that. I guess maybe if it was something I'd want to read, but didn't feel I could do it justice, it might be worth it, but then I'd always wonder, "Would I have been able to write it this well or even better?"
I won't lie, though, Mare - if you offered to finish Guilty Roads for me, I'd probably be like, "Here, have at it!" Perfect example of a story that would probably be a lot better in someone else's hands, someone who was better with the suspense part than me. I could keep writing about Koma Kevin and let someone else take over Nick LOL.
