It's a shame to hear that. I expected a full fledged adventure game with puzzles that would make you sweat blood and with narrative worthy of at least a paperback novel. Maybe they will make it up with the second part.
I suppose Tim Schafer is not much of a management guy and Double Fine got a little overwhelmed with their 3 million dollars. Tim is very creative and funny, but maybe he needs a little direction. In any case, it's good that a game like this was made. Perhaps it will mark the return of the genre on a regular basis.
There *are* other decent adventure games out there, though mostly indies. Daedalic (Deponia, The Whispered World, Chains of Satinav, Memoria) makes fun, relatively polished games but still has much to learn in mechanics and characterization. Wadjet Eye games are somewhat raw. And Amanita design are more art showcases than proper games, although Machinarium was awesome (but short). Telltale is busy consolidating their own approach: interactive narrative is fun, but games like The Walking Dead barely had any puzzles or logical thinking. Their former games, including Sam & Max seasons 1, 2 and 3, Tales of Monkey Island, Wallace and Grommit, and even Puzzle Agent, are all fun but again, really lame puzzles. Out of all these, I think ToMI has the most polished puzzles, but the episodic nature limits the scope of well, everything. We barely have any traditional adventures left, so maybe after the Broken Age experiment Double Fine will have something better to offer.
I admire inXile for their approach though. Tim Schafer might have broken the kickstarter game scope but Brian Fargo has shown he really knows his business. Wasteland 2 might yet become a modern classic, while Broken Age is probably just probing the adventure game "market".
