I just want to point out that this is not directly related to RPing, but I want to discuss it in the context of RPing. If a mod feels the need to move the thread, go ahead.
When RPing, one thing that most people make sure to do is set up a story with no main character, so that no one feels that another character is more important than theirs and so that the loss of a single player/character will not immediately ruin the story. Because about 90% of my creative writing over the past few years has been RPing, I have fallen into this habit when planning solo projects as well. I noticed while planning out the plot for a book I'm planning on writing that I had not created one main character and a plot that involves that character overcoming an obstacle, I had written a basic plot and a cast of major characters who all had approximately equal value to the plot. Think Harry Potter on one side (single protagonist), and Game of Thrones on the other (many characters, none of them emerging as the sole main character).
I understand why most novels have a single main character, it gives the reader an easier time connecting with the character, but why is there not a larger market for books where the plot is the main object and a cast of characters is used to tell the story of the plot? Also, do you think it would be easier or harder to write a successful book with no main character? (Note: I do not think my book will be successful, or even finished. I have a habit of only sticking with solo projects for a month or two...)
A second point is that RPs, while obviously inherently different from novels or other written mediums, often have pretty amazing and well thought out plots. While an RP would not be suitable to release as a novel without major editing, do you think that a novel based on the general plot and characters of an RP could work? Obviously this would be a story with no main character, which is why I am including this question here.
Sorry, a little ramble-y, but I think I hit the main points.
