In RPG terms, very little, which I’d love to change. Dissecting Worlds remains my favorite show for exploring narrative architecture and social science stuff(And we will get that Ian McShane Knight Rider made somehow, damn it!).
I’d also recommend The Magnus Archives from The Rusty Quill (Especially episode 100 for…reasons) in general and their RPG show in particular. The Infinite Bad from Definitely Human is excellent too.
For actual design discussion I’ve not found much. So if you’ve got something you’d recommend, come say on twitter and let’s chat about it:)
Here’s my published work so far. If you want to talk to me about a project you’re hiring for, get in touch. Alternately, come say hi on Twitter and I’ll see you back here tomorrow.
