Have to agree.. least rewarding Zelda game I've played.. there's no sense of achievemebts for the dungeons (outside the 4 main).
I mean, each shrine gives you what is essentially a heart piece... though I admit it doesn't feel quite as rewarding as finding a heart piece in past Zelda games.
I wish they had given armor out more often as a reward - finding new armor was always super rewarding in this game
