During this internal prototyping process, game developer Double Fine allows any staff member to present an idea for a game. Those with the top ideas then become project leaders, and are tasked with creating a prototype of the game idea within a two week period. The remaining staff then vies for which prototype they would prefer to work on, and from that process, small development teams are formed.
The top game ideas are usually chosen by Double Fine's founder, Tim Schafer, however, during the 2012 Amnesia Fortnight, Double Fine partnered with the Humble Indie Bundle to give anyone who donated a minimum of $1.00 the chance to vote for the top ideas, watch the process, and play the finished prototypes. The top five ideas (Spacebase DF-9, Hack n' Slash, The White Birch, Autonomous and Black Lake) were then chosen to become prototypes, and this two week game development process was documented by 2 Player Productions. At the end of the two weeks, each prototype became available for download to all those who donated.
Many of the past resulting prototypes have gone on to become full game releases, the first being Tasha Harris' Costume Quest, a turn-based RPG. Other releases include Stacking, Once Upon a Monster and Iron Brigade.
In early 2014, Double Fine once again joined with the Humble Indie Bundle for another Amnesia Fortnight. The three projects that were picked for prototyping were Dear Leader, Steed, and Mnemonic. Additionally, "Little Pink Best Buds" was chosen to be Pendleton Ward's upcoming project. On March 7th, 2014, prototypes of all four games were released for anyone who contributed to the Humble Bundle.
