Here's a neat idea: the latest Humble Bundle allows backers to cast votes on game pitches put forward by the developers at Tim Schafer's Double Fine studio (via Gamesindustry International). A minimum contribution of $1 gives you the right to vote, and the top four contenders will be cobbled into prototypes during the developer's upcoming Amnesia Fortnight .
The two-week internal event breaks the Double Fine crew down into smaller teams intended to bring fresh, new ideas to the table. It's worth noting that previous Amnesia Fortnight gatherings birthed Double Fine hits like Stacking and Iron Brigade.
With Humble Bundle in the mix, Double Fine's developers have put their prototype pitches forward for contributing fans to vote on. Once the list is whittled down to four, each team will have two weeks to put together a prototype around the idea. Those prototypes will then be given to all contributors, along with additional prototypes for Costume Quest and Happy Song (which became Sesame Street: Once Upon a Monster) and a 2 Player Productions-produced accounting of the process.
