If you haven't pledged your awesome support for this yet, your time is running out! It's not like Mr. Schafer is in desperate need of more dollars or anything (what a crazy turn out, at over $3mil!)... But this is about more than just money. Besides the fact that you get to support one of the industry's coolest dudes, and the man responsible for some true gaming culture icons, you get a copy of their to-be-made masterpiece for only $15. But more critically, you contribute to the message of independent optimism that this crowd sourced project represents. The little guys are starving; the big guys laugh maniacally on their mountains of cash... This resounding message that we embrace independent artists is a triumph. It's worth $15 just to say "I want my beloved gaming culture to be about more than World War II shooters".
UPDATE: Time is up, but totally watch this video and then go cyberstalk the Double Fine team. I love these folk.
Also, Tim Schafer once called Bobby Kotick a prick. That's a bargain at $15 right there.
