A former roommate of mine is finishing a game (inspired by Ender's Game) with Kickstarter funding, and they've actually released a playable prototype for backers--even though the Kickstarter campaign isn't even over yet.
You can buy micro-currency in advance and in exchange receive perks similar to KickStarter. By running it themselves, Grinding Gears gets access to the funds and can dish out the benefits immediately.
Examples:
* Double Fine Adventure - http://www.kickstarter.com/projects/66710809/double-fine-adv...
* The Banner Saga - http://www.kickstarter.com/projects/stoic/the-banner-saga
* Wasteland 2 - http://www.kickstarter.com/projects/inxile/wasteland-2
* Shadowrun Returns - http://www.kickstarter.com/projects/1613260297/shadowrun-ret...
Even smaller games are getting funding this way:
* Valdis Story - http://www.kickstarter.com/projects/460275866/valdis-story-a...
* Echoes of Eternia - http://www.kickstarter.com/projects/1465600975/echoes-of-ete...
