Double Fine's Broken Age Kickstarter received plenty of attention during and after its lifespan due to being what was at the time the most successful project on the crowdfunding site, video game or otherwise.
Some of that attention proved to be negative, with scrutiny becoming particularly fashionable when the scope of the game, and therefore its schedule and cost, began to inflate. I always saw it as a weird sense of entitlement that required the willful misunderstanding of what a donor is (versus an investor), but at any rate there was, at one point, in some circles, what you might call a controversy.
But it doesn't seem to be a controversy the studio has profited from. Reports Schafer:
"My expectation with Broken Age in the end was just to break even," Schafer said. "With Kickstarter, the risk is gone of losing money on it, so you know you've broken even if you just make the game to that amount of money. But we made it [for], like, twice as much almost as we got in. Or more. So we will just about make that back."
Tim clarifies that the purpose of crowdfunding from his perspective is to remove the categorical dependence on publishers, and by that criteria, the Broken Age experience was very successful.
