If I could, I'd attempt to do one with a count of 50,000-100,000. I'd even put it in script format, if I could manage it.
I do need good dialogue. I actually attempted to spitball my version of the ending here once, but gave up once I had to get to a point where a character would speak. I don't exactly consider myself the best authority on how these characters would react or speak, especially in the new circumstances they're presented with. Maybe I'll test my skills, and try it out on you, or something. *shrugs*
