Update: Added release date information and the newly-released trailer.
Double Fine has called take-backsies on its previous decision to release Broken Age as Early Access. Rather than launch in an unfinished state to raise funds for polish and the second half, it will be a standard Steam release as a "Season Pass" to purchase both parts at once. Backers will get to play Act 1 today, and the unwashed masses will be able to play on January 28.
"You may recall that at one point Broken Age was planned for release under the Steam Early Access program," Double Fine wrote in a Kickstarter backers update. "This is no longer the case. For various logistical reasons, and because we believe Act 1 is a polished and satisfying piece of content in its own right, Broken Age will be a standard Steam release that includes a 'Season Pass' granting access to Act 2 once it is complete." It goes on to note that however you get Act 1, by being a backer or purchasing it, you'll get Act 2 automatically as a free update. Double Fine eventually plans to release for Ouya, iOS, and Android as well.
Broken Age's Kickstarter success helped put the alternative funding model on the map, but its announcement of splitting it to help raise further funds caused some consternation in the community. Now it's reversed that decision, but it probably won't be the last of crowdfunding growing pains for the industry.
