Each year Double Fine Productions drops everything they're working on and allows any willing employee to pitch an idea for a new game - this is dubbed Amnesia Fortnight. This year the company has opened up the process to the public, and allowing people to contribute funds in order to vote for their favourite game ideas. Hosted on Humble Bundle, the contribution each person makes can be divided up based on personal preference between Double Fine, the charity Child's Play and the hosting. Contributors also receive prototypes from the two previous years: Happy Song (the prototype for Once Upon A Monster) and Costume Quest as well as the top four prototypes based on this year's voting. Contributors who pay more than the average amount also receive the prototype Brazen, a four-player action co-operative game led by Brad Muir. The fortnight will be live-streamed and documented by 2-Player Productions.
