Unless I'm missing something, Fig's model also asks the community to shoulder the risk. The only substantial difference is that with the Fig model the community also shares in all of the potential upside, whereas Kickstarter offloads the risk, but caps the maximum upside at getting the game you backed.
To be clear, fig also provides the Kickstarter model alongside its investor model. So you don't have to choose one platform over the other in terms of how you want to risk your money.
