Double Fine Adventures isn’t breaking new ground by being a crowdfunding project for a video game. Nor, from what I can tell, are they really doing too much different in their approach to it. (With the exception, perhaps, of the inclusion of a behind-the-scenes documentary of course.)
And possibly intrigued by the hype created by Double Fine’s project, Obsidian Entertainment and Planescape: Torment designer Chris Avellone recently poled fans to see what they would want to see if Obsidian were to Kickstart a game project of their own, and the thread got 1000 hits per second. (Not surprisingly, Planescape 2 was at the top of the wish list.)
Lastly, if anyone is interested in seeing other game kickstarts, IGN posted a little piece entitled Five More Video Game Kickstarters to Fund.
