So if one of these kickstarter people ends up using the money on hookers and blow you don't get any of your money back?
Well that's part of the risk of kickstarter unfortunately (it's an investment basically, not a loan and you can get burned by it). I feel like Kickstarter does a good job weeding those kind of people out though, every project i've pledged to so far have been pretty reliable with updates and getting their projects completed.
Also helps when you have respected members of the industry at the forefront of these kickstarter campaigns like inafune (who had worked on mega man titles and other projects at capcom for like 25 years)
