For those not in the know, Double Fine Productions was founded by Tim Schafer, who is ex-LucasArts and was lead on Grim Fandango and heavily involved in the Monkey Island series too.
It's been years since I've played a good adventure game, and Broken Age definitely scratched that itch.
I played the latter half of Shay's storyline with my daughter (she was amused by the teleporter's side effects), we're going to replay Vella's storyline since she missed that part.
A game that did manage to get it almost entirely right, though (not extremely visually appealing when compared to 2d art, but still decent), is The Book of Unwritten Tales (and also its prequel, though I did not like it quite as much).
Oh, and there is actually a ton of fantastic, and free, adventure games made by amateurs over here: http://www.adventuregamestudio.co.uk/site/games/
People don't talk about the games made by the AGS community too much, and they keep a lot to themselves, which is a pity, because there are some true gems there.
It's an extremely self-referential parody of adventure games, made by guys who clearly love the genre. I found it a lot of fun.
Ron Gilbert was also involved in Broken Age, as far as I know.
