Since they added the Games section, Kickstarter has been flooded with game projects. A small portion of them are successfully funded.

It seems that Kickstarter alone isn't enough to get funding - putting your project on Kickstarter and then leveraging some other form of publicity has a much higher change of success.

As a side note:

My company builds html5 multiplayer game technology. I'd love to talk about your project - you can reach me at tom@gameclosure.com
