Plotbuilder

From the web page: Plotbuilder is a deck of 72 setting and system neutral cards designed to inspire creativity and help create story arcs. Starting from the drawing of a Character card (who is the main protagonist), the deck will then define an Organisation, Method and Motive. Of course, the important bit of any plot is a Result – what will happen if the plans all work out. As an added bonus, you can also draw a Twist; indicating when the whole thing is not as it seems.
