The Double Fine presentation from GDC 2012 has made its way to the GDC Vault where you can now watch it...as if you were there.
Creative Panic: How Agility Turned Terror Into Triumph is an hour long talk about Double Fine's Amnesia Fortnight and the four games it birthed given by Tim and the respective project leads (except Tasha Harris, who was reclaimed by Pixar). I like Tim's recollection of the cancellation of Brutal Legend 2: "Well, that's interesting - we're gonna go out of business."
