Road Redemption is a Road Rash like game (curiously I came across the video after viewing the Open Rash video so hat tip there!) and is kickstarter backed. What really piqued my curiosity is the statement 3.5mins or so into their trailer / promo video that they will "release" their source code, art assets, and project files. I quote "release" because that may not necessarily mean an open source license. That much was not disclosed.
Still, it definitely is interesting to see this kind of thing coming out of commercial (albeit independent) development houses.
