I know some people have a bone to pick with Double Fine. I get it. I was a backer for Broken Age too. I saw what happened to Spacebase DF-9.
But Massive Chalice, Brutal Legend, Psychonauts, all these override any negative. For the flaws of Broken Age, it did get made, and the documentary vids were part of why I backed. I got my value from that. Psychnauts is amazing in many ways. I would love to see more of that universe.
So while I do share some of the reservations about Tim Schafer as a project manager, as a designer and writer I hold him in esteem like few others in the industry. Backing is certainly a risk, but there is no chance I would skip doing so. This is a game I want to exist, and a game I would play no matter what if released.
