P1na: Stupid question, but what happens to donations for all these games that don't make it?
I ask mostly out of professional interest, as I currently run a crowdfunding site and am in the middle of designing a second one. We usually give back the money if a project is not successfull, is this the case here as well?
Kickstarter will charge your card at the end of the run, only if the project was successful. Thus if the project fails, no charging on your card (though it is possible to check that the card can be charged when you first pledge).
Indiegogo depends on the project plan, it can either charge at the end of a successful project, or charge when you pledge, and give the money regardless of success or not.
