15. Longest RPG campaign played
Face-to-face, I think that would be “Aldana Steel,” our 7th Sea campaign that lasted from 1999 to 2004. Online via VoIP, probably our Savage Worlds: Dark Heresy saga, from about 2009 to 2013, I think. Online text-based: probably “Big Trouble in Little Al Amarja,” an Over The Edge play-by-email from about 1996 to 1999.
The Reef 
My longest PbP game was the Alternate History Travel Guides. Ran from March 1998 to August 2004. 6 years of goodness. Second to that was the PbP game Catastrophe in Clydesdale! A MLP Wushu game.
After that, it’s the Online game of Burning Beards, a Burning Wheel campaign on the Sunday Skypers that’s been running for 3 years now. It’s coming to it’s first big break as we are close to consolidating our hold on Scoria Deep. It was originally only going to last 5 to 6 episodes, but we got into the politics of being dwarves and it took off from there.
