Broken Age (formerly Double Fine Adventure) (Finally complete!)
So Tim Schafer is finally making another honest-to-god adventure game. Almost nothing is known about it except for the publisher: Us
More specifically: Kickstarter. ($30,000 already and the site went up less than an hour ago)
It's going to be a smallish point-and-click game with a projected minimum budget of $400,000 to be released in ~October. $15 gets you the full game and beta on Steam + lots of documentary footage of the game's development. There are all sorts of reward tiers over $15 so you should probably look!
They're also talking about an iOS version but it all depends on the funding.
There's a neat video on the site, BTW!
