So I got this "idea".... why not take all our main characters, decide a story, and work it down by chapters?
say my main project character is Sesilou so we'd put him working along all your main characters while working for a main goal.
HOW CHAPTERS WORK:
Ok so, since it's a collab there won't be only 1 game folder, rather many... say 1 rpg maker game is 1 chapter... since it's a collab, each of us makes a chapter while centering it to his/her main character while keeping the storyline in sync.
For example let's say... asth got chapter 3 and I got chapter 4,
Asth makes his chapter centered in his main character, while using ANY battle system he'd like, he just makes sure his chapter keeps up to the plot. afterwards once his chapter is done, that's my cue to make a new rpg maker project, my project starts off where asth's chapter ends... but mine will be centered on Sesilou and a battle system of my choosing, so where my chapter ends, someone else's project starts
hence how we actually make progress in-game. all we'd need is the storyline, how we can split chapters, and what battle system to use on the final chapter (this one is a bit special)
so.... besides me, any other volunteers to a collab?
