LOVE the idea sparkles but I doubt starting it big will be easy so you might wanna start out small like a one page story to start it though. (note to self: don't talk like I do stuff like this XD)
2nd thing although I highly doubt it you might wanna confirm that people have no problem with you using their character/in game name in your story. like make a list for people who want to be Exclude from it (should make it very short ).
