Build a World from Conjecture and Nonsense • 2016 supplement

Setup: a few printed maps at different scales, markers, blank paper

GM: Present the group with a few maps, ask them to choose two they like. Anything from the galaxy to the local mall. Write the following on a piece of paper with room under each:

Premise: Basic idea of the campaign
Cast: PC names and descriptions
Histories: Past events that affect the present world
Mysteries: Rumors, lies, unknowns
Places: Places your players know about
Treasures: Things the players want to have
Contacts: Friendly people the players know
Adversaries: Who will stop the players? 

Ask leading questions until you have a few of each. Offer guidance on what you think is fun, but let the other players do the work. Later, combine these to plan adventures.

PCs: pick two maps. The larger scale map is your world, the smaller scale map is your turf.

Tell your friends what you would like to see in your adventure, until you have a premise. Ignore the intended setting for your chosen rules.

Carve up the maps into various factions. Draw points of interest. Answer the GMs leading questions, and draw those on the map too.

Finally, make characters to fill out the cast.
