The Game Designer - Kickstarter and Feature Creep.
I have supported Kickstarter projects in the past, and I have never had an expectation that the scope of a project would increase if the funding exceeded expectations (unless this is explicitly specified with stretch goals). For me personally, I wouldn't have gotten mad if Double Fine had simply delivered what they promised and "pocketed" the extra money. If they are getting paid accordingly to do what they love, without having to work for a big evil publisher, they will almost certainly make more games. So any "extra" money is just going into those future products.

My logic on this is that the crowd-funding paradigm looks to me an awful like the "pre-ordering" paradigm. You pay ahead of time for a product, in exchange for some positive benefit. In software, this benefit might be a lower price or a bonus game level, or even just the assurance that you will get the game on launch day instead of having to waiting in line. This is the customer/publisher relationship. If a traditional game publisher has more pre-orders than planned, they don't expand their scope accordingly. In fact, the very idea is silly. If EA projects that Madden pre-sales will be 250K and they hit 300K, the development team doesn't run back to the studio and try to squeeze in an extra feature before launch.
