Call of Cthulhu, RuneQuest, 7th Sea: the Glass Cannon Network played demo games of them all at Gen Con, one after the other, in the space of one hour 45 minutes!
In a virtuoso GMing performance, Chaosium's Brian Holland introduces these TTRPGs to Joe O'Brien, Paula Deeming, Matthew Capodicasa, and Josephine McAdam. These quick demo scenarios were created by Brian (Call of Cthulhu), and fellow Chaosium team members Andrew Bean (RuneQuest), and John Wick (7th Sea).
