Great writing advise and insights here from novelist, screenwriter, and game designer, Chuck Wendig:
I’m a panster at heart, plotter by necessity — and I always advocate learning how to plot and plan because inevitably someone on the business side of things is going to poke you with a pointy stick and say, “I want this.” Thus you will demonstrate your talent. Even so, in choosing to plot on your own, you aren’t limited to a single path. And so it is that we take a look at the myriad plotting techniques (“plotniques?”) you might use as Storyteller Extraordinaire to get the motherfucking job done. Let us begin.
THE BASIC VANILLA TRIED-AND-TRUE OUTLINE
The basic and essential outline. Numbers, Roman numerals, letters. Items in order. Separated out by section if need be (say, Act I, Act II, Act III). Easy-peazy Lyme-diseasey.
THE REVERSE OUTLINE
Start at the end, instead. Write it down. “Sir Pimdrip Chicory of Bath slays the dragon-badger, but not before the dragon-badger bites the head off Chicory’s one true love, Lady Miss Wermathette Kildare of the Manchester Kildares.” Rewind the clock. Reverse the gears. Find out how you build to that. Find the rest of this piece at Wendig’s blog terribleminds.
