Yeah, that game has to take the prize. The first three chapters take about six hours or so and that just unlocks the full battle system, so it's like the intro. After 20 hours or so you get to Pulse, which is the open world in chapter 11, before that every map is pretty much linear. (Lots of Japanese RPGs are like this for some reason... it takes a super long time in DQ VII to even get to the job system which is at the heart of the combat system)
As for shortest, well there are a lot of open world games that start off completely open, so not sure how you judge that.
