I spent all of Saturday playing this game, it's absolutely incredible.  I'm at the final boss, after two days, but I probably played about ten or so hours straight Saturday, so that'd be why 

The figurines are easier to acquire, but there are a lot more, too.  So the time it's taking me is almost the same (with Wind Waker being a bit harder, obviously).  I will get them all, though.
I have more kinstone pieces than I know what to do with, though.  I have a feeling that I'm going to go for 100% completion in this, or at least something very close.
