I have a suggestion for the SGU's May 2nd 2015 10-hours-for-10-years live stream event. Some of my favourite show moments involve The Rogues competing with one another (usually Science or Fiction, obviously.) I also love that many of them are into gaming, particularly RPGs. I think it'd be great to see the rogues play an RPG game live on the show for a couple of hours.
I don't know much about RPGs like D&D, so I don't know how feasible this is, but perhaps if the game would take too long (or drag on), it could be modified to be only an hour or two? It could have a science and skeptical theme...or not, as The Rogues have gone off on tangents regarding their love for fantasy and sci-fi on the show in the past (the James Marsters interview comes to mind). Again, no doubt Steve, Evan, et al. have much more experience with RPGs than I, so they'd be a better judge regarding whether or not this would work.
