I spend an hour mostly talking about dice. I spend as little time as possible looking at the numbers and probability curves (but have to spend some time talking about them) and then go on to talk about how those apply, how dice can strip agency from players and how to avoid that happening. I also do a big breakdown of what you can do with playing cards and why, sometimes, you shouldn't.
I touch upon a lot of games, including Under Falling Skies, Warhammer 40,000, Savage Worlds, Dystopian Wars, D&D in its various incarnations, Aristeia!, Infinity Defiance, and Malifaux.
These unscripted episodes get long. Hope you're all cool with that.
