While I know that Just A Minute is fun (I've run it myself, as well as played it), and that Paul does well with it (both seen from an audience and been a panelist for him), I do think you'll need to do some promotion for it. It didn't fill up a small-to-medium room in Montreal, and most non-Brits/Gallifrey attendees won't be familiar with the game. If possible, I'd suggest getting some significant name panelists for it as a start, along with a pre-Masq writeup/plug in the newsletter.
