Came across this posting from Fan Expo Canada 2015 by a panel of some notable – and in all honesty – funniest writers currently producing Sword & Sorcery comics, fiction, and games. While my personal approach to humour in the games I run, is to let the players set that tone and work to build upon those circumstances they’ve found to be funny, or made funny by their reactions, there’s a lot of good advice in this recording (runs approximately an hour long), and is certainly worth the listen even if just to learn how professionals go about cultivating humour in their writing.
