## Publication history

Cubicle 7 used their license for Call of Cthulhu to publish the Cthulhu Britannica (2009) core book,$^{:432}$ the first product in the line which included five scenarios.

## Legacy

Stu Horvath in the 2023 book Monsters, Aliens, and Holes in the Ground, Deluxe Edition: A Guide to Tabletop Roleplaying Games from D&D to Mothership explained how "Before renovating Call of Cthulhu proper, Mike Mason and Paul Fricker did interesting work at the helm of Cthulhu Britannica for Cubicle 7 (2009), which also produced an odd fusion of war story and cosmic horror with their World War Cthulhu line (2013)."
