It gets a little more interesting when you're promising tangible rewards in addition to completing the project. For instance, if I say "$50 will get you a T-Shirt", it seems reasonable to me that I am contractually obligated to give you a T-Shirt even if I am unable to follow through on completing the game to the desired standard. The extra rewards certainly seem like more than just a "donation".
