Favorite media you wish was an RPG
Oh, this one is a total no-brainer. I even made a fake cover for it:
Let's see: civilized PCs, high magic, political intrigue, five volumes of the fiction written in a style that deliberately channels Dumas and Sabatini, along with some of the best "NPCs" in fantasy fiction? Yes, please.
(And yes, I know there's a Dragaera City expansion coming for John Harper's "Blades in the Dark" RPG, but that's just focused on the Jhereg. I want it all! I want the whole scope of this marvelous world.)
