So if this team just decided to run off with the $1.6M right now for essentially writing a page worth of text and making a couple concept videos, would there be any legal recourse for the donors? Not that I have any suspicion at all that that's what this team is doing, but Kickstarter projects in general seem like a relatively easy way for someone to make a good chunk of money for the cost of a couple hours' worth of work.

Is there really nothing more to it - donors just have to cross their fingers that the team is legit and isn't just going to run away with the money?
