As I have previously stated, they owe you nothing. It is a donation, not a preorder, not a purchase order, a donation. Anyone who donates to Kickstarter and expects to get something in return is doing it wrong. You are donating to help get a project off the ground, not to get your share of the project's pie.
Eh, when the project is funded, you should expect to get a product. Quality of said product will vary, but you're getting one, otherwise the
entire rewards concept wouldn't work.
Kickstarter isn't the make-a-wish foundation, and it stopped being that way when professionals started raking in serious money. When you're offering pre-orders for a game on funding, that is a business arrangement. The only practical difference is that the ToS prevents people from suing for false advertising or anything else, under the term "donation." Remember other creative uses of the ToS agreements, like the ones that turned video games from products you own into products you've been licensed to use?
Imagine if the American Way or some other
charity was like "give us money. But it's not guaranteed to turn into anything you'd want!"
In an ideal world, yes, Kickstarter would be just like the Make-a-Wish foundation for developers and entrepreneurs. But in practice, it's re-branding capital ventures as charity to avoid all the constraints AND protections that are normally in place.
On the storming of the Vatican, it would be really amusing to see people rush in with swords and such, and straight into the Swiss Guard armed with the latest military hardware.
