I don't see any issue with the idea of pledging and kickstarter as a whole. There is risk just like with anything else. But it's one thing to risk 45, it's something else with it's 250. I mean, 250 is 250, with the risk of getting either a) zero return due to the game not coming out or b) the game coming out with a much different idea than what was conceptualized due to a variety of factors (money, time, resources etc).
I guess it's all about hope. Problem is there has been hope before in this genre of games. Many times over. Sometimes you're just tired of getting burned.
