So I'm completely not sure about if we should soft reset after the final boss in each story except for the last story you go through or just keep skipping cutscenes after the final boss in each story, then either save or return to title screen like we have been doing in All Stories. What I'm worried about if we do start soft resetting after the final boss in each story is if someone doesn't go through Aqua's Story last and doesn't get the correct Final Episode save and the inaccurate in-game time at the last Battle Report. Unfortunately I didn't think about discussing All Stories Any% rules until now.

I personally see no reason to skip through the cutscenes after each final boss unless there is something that occurs afterwards that impacts the rest of the run. The way I see it, if nothing else happens after the final boss other than some cutscenes/the battle report, then soft resetting is fine.

Your part about the Final Episode is valid though and in that case a rule might be that you do have to end on Aqua so that you can get the proper Final Episode.

No reason to skip cutscenes in my opinion. The normal any% routes end at beating the final boss so you should be able to reset after them for all stories too.

Another reason is to save after the final boss in Ven's and Aqua's Stories if you did get the Xehanort Reports during the run so that way the game knows you got the Xehanort Reports.

But can't you already have the reports from preset saves? or is that not allowed?

If you have all 3 characters completed, then you would get extra Disney Town cutscenes for all characters. Which is why we would usually just have a completed Terra save with all of the reports collected in his Story while we would get the Reports in Ven's and Aqua's Stories during the run.

But do the Disney Town Cutscenes take more time than end game cutscenes? Honestly, it would have to be taken into account. Depending on time loss it may be worth to have all 3 completed if you want to run All Stories.
