I'm aware that there have been many questions asking for views on what makes roleplaying fun, what makes characters interesting and generally how to make things fun for players over the course of a role-play. My question, however, is a little different, and I did perform a quick forum search for an answer, but to no avail. I figured it would be beneficial for myself (and maybe for others) to open a new thread to get some fresh opinions.
What makes a good PLOT? Plot only.
What makes a story more interesting than your cookie-cutter adventure before you even take into account players and their potential impacts on the world? How do you make a story enthral from the onset and invoke emotion in players (or readers, if you were writing a novel). What aspects make a story great, what tropes and ideas. What themes interest you, and what, when changed from stereotypical stories, will make a story one for the history books. What kind of narrative voice is more powerful than an indiscriminate omniscient narrator, what techniques keep you coming back to a story?
