Which, I think was a problem for several reasons that were unexpected for Double Fine:
1) They didn't expect to get even remotely that much money.
2) They underestimated how long it would take to make the game, especially with the new budget. Really, three years to make a game from scratch to completion is pretty common.
3) Making it from scratch was one of the initial problems. Most good Kickstarters already have working gameplay to show.
4) The Kickstarter was also more than just the game. It was also the behind-the-scenes documentary, which was fantastic.
5) They hit unexpected financial snags, some unrelated to the money they made from the Kickstarter.
I won't defend them entirely, but really, they came through on their promise. Broken Age is now officially out and done, for all the good and bad entailed with it. I don't regret backing it. If I were to ever back another of their Kickstarters, it'd have to be one that already has gameplay footage. Which Broken Chalice didn't have initially (and it wasn't a game I was interested in, anyway).
