"Guys, I want to love you so badly... I met you at PAX and was worried how the exchange was going to go, considering we're so far behind schedule, updates are very insufficient, and I pledged at a high level ($313). You were very apologetic and assured me that things were going to take off right after PAX, but that is another commitment that hasn't been met. I'll be happiest if I can get my money back, but I doubt that's a possibility. I had time and energy to dive into this stuff earlier this year. Now I'm married, working different hours, and have a very different life. Lots has changed since the estimated delivery date flew by."
You were funding a product that you were told may or may not meet with success. You're now going to need to show in a civil court that there was wilful recklessness in the use of funds.
Kickstarter sits on the fence, too - it states that the creater is obliged to deliver pledges or refund, but that it hopes requests for refund will only be used for bad faith projects.
Given that he gave a video interview in November stating he felt the project had a year to go, and that the pledges specify "Estimated Delivery" only, I think that's a hard road to plow, leaving aside the fact that a malicious, or even unlucky/ill-planned project could keep pushing out the dates.
Some investments fail. Too many people view Kickstarter as an online store.
