I set in to a fit of giggles when I bring EU content into my campaign, often as little easter eggs.
I tend to avoid bringing the major movie players into the story but I brought in a cousin in the Organa family, mentioned Lobot on Bespin, had Cay Qel Droma in a Holocron, and a padawan was possessed by the spirit imbued mask of Darth Nihilus.
Have you brought EU content into your Edge of the Empire campaign?
