Double post, sorry.
Here's my list of "chapters". Given that we have 19 sign-ups, I tried to keep it down to a minimum. Obviously people can write more than one chapter if they want!
1. 1st bombing mission
2. Childhood friends
3. Aerith
4. Wall Market
5. The dropping of Sector 7
6. Breaking into Shinra
7. Travelling to Junon
8. The Inauguration of the New President and the journey across the sea
9. Gold saucer and the Corel Prison
10. From Gongaga to Cosmo Canyon (could split in 2)
11. Rocket Town
12. The Wutai sidequest
13. Gold Saucer and the Date
14. Temple of the Ancients
15. Sleeping Forest and the Forgotten Capital
16. The Great Glacier and the confrontation with Sephiroth
17. Meteor (I imagine this being written from an NPCs viewpoint)
18. Escape from Junon
19. In the Lifestream
20. A trip into Outer Space
21. Diamond weapon and the return to Midgar
22. Before the final battle (where did they all go and what did they do?)
23. The final battle with Sephiroth (good for someone who likes writing action scenes)
24. The Lifestream
The way I imagined it was, each "chapter" could/would be told from a different viewpoint, though not necessarily in the first person. Eg. Chapter one could be told from Barret's viewpoint (or Jessie's), chapter 2 from Tifa's, chapter 3 from Reno's, and so on.... Each major chapter can be linked or sewn together by a minor "transition" chapter which I can write if nobody else wants to.
Basically we assume that our audience already knows the story, and therefore we don't have to re-tell every single thing that happened in the story; rather, we're focusing on key events in the story and looking at telling them from a new angle, or with insights and details. For example, I imagined Chapter 17, "Meteor" being told from the p.o.v. of one or more NPCs.
Although it looks as if there's lots that's been left out of my list, much of it can be worked into the different chapters, since every author will have a free hand with his/her segment.
The list above is just a rough list for discussion. All suggestions are very welcome. However, given that we only have 19 authors signed up, we want to keep the main chapters to a minimum otherwise everyone is going to end up writing two or three chapters!
