I am revisiting a tiny zine I published a year ago, you can find the original files here.
The zine was about a surreal whimsical city where humans coexist with living doodles.
How would I game using this odd setting?
Cthulhu Dark: you could use Cthulhu Dark and as the insight of the characters raise they begin to understand that everyone and everything are drawings, they get glimpses of object in our 3d reality, they understand that they exist as multiple copies, both printed and digital. If you need menaces they are intrusions from other realities.
Troika: well you can write custom background for native of the Doodles City or you can simply send your group of Troika characters in the city and play as usual.
Tunnels Goons: use the basic rules to play citizen of Doodles City, items must be draw on the character sheet to be use for rolls.
Show the maps to the players, when they visit a building or a location, ask them what they think the doodle represent and run with their ideas. Roll or select one or two descriptors for each keyed locations.
