In a GDC panel called "Creative Panic: How Agility Turned Terror Into Triumph," project leads from Double Fine's quartet of "Amnesia Fortnight" projects each outlined the process and inspiration behind their games -- with the exception of Costume Quest's Tasha Harris, who didn't share her insights because she wasn't there. "Amnesia Fortnight is a psychedelic mushroom and we all took it," studio head Tim Schafer said, before adding that it was really a two-week team game design exercise held in the middle of Brütal Legend work.

Born from a break in AAA development, the Amnesia Fortnight forged a new direction for the company when Brütal Legend 2 was canceled.
