The 9Qs

From author's site: Derived from screenwriting techniques, the 9Qs are nine questions that will swiftly guide a solo player through the progressive stages of an adventure in any genre by generating the inspiration needed to create thrilling RPG encounters. Playing through those encounters with any RPG rules system will produce exciting and unexpected results as the solo player alternates between acting as the Game Master and directing the Player Characters. The engine will work well with a variety of random idea generators, including Rory's Story Cubes and the Mythic GME.
