If you're a fan of Double Fine then you're probably aware of their annual "Amnesia Fortnight" event. If not, it's when the developer stops working on their commercial products, splits into teams, and takes stabs at prototyping new and different game ideas for two weeks. From there, the games aren't often followed up on, but on occasion they have been. For example, Costume Quest and Stacking were games which came from a previous Amnesia Fortnight.

This year, the developer teamed up with Humble Bundle. They proposed a handful of ideas that those who purchased the bundle were able to vote on. This process lasted about a week and now the votes have all been tallied. The Amnesia Fortnight bundle already had a handful of Double Fine prototypes up for download (Brazen, Costume Quest, and Happy Song) but now it is getting the four top-voted titles.

These four games selected are Autonomous, Hack n' Slash, Spacebase DF-9, and The White Birch. To make the whole process even more interesting, Double Fine will be streaming their work on said games for the two weeks until delivering a prototype. It is also worth noting that there is no commitment to make any of these Amnesia Fortnight games into commercial products, but you never know what may happen.

Curious about what these games are about and if you should pick up the Amnesia Fortnight bundle? Here are the introductory trailers for each:
