TP actually had some good exploring aspects, there were LOTS of little nooks and crannies, the problems were,
A: 90% were in Hyrule field or Lake Hylia, leaving the rest of the world to be empty.
B: there wasn't really any NPC interaction or quests involving exploration, other then fetch quests.
C:you only really found chests of Heart pieces or money, no puzzles or suprising rewards or quests.
PS
oh cool Faceless, i that case i actually agree with you...
That's because Hyrule Field comprised about 90% of "TP"s world.
It's not anything new with this game that treasure chests contain primarily heart pieces and rupees. That's been the case for awhile. "Windwaker" changed that up a little by scattering treasure charts around the world (as well as triforce shards.) What we used to have, though, in the old days, was like in "A Link to the Past" where a very helpful Magic Cape is stealthily placed under one of the graves in the cemetary, and you have to do a Pegasus Dash into it to reveal it. Just pushing it will not suffice. But that wasn't in an actual treasure chest. Or how about in the original NES title where the power bracelet was underneath an Armos statue and the Magical Sword under a grave? Or better yet, how about all the Secret Seashells in "Link's Awakening" you actually have to meticulously dig around for, and for which finding all of them leads you to a nice power-up in the Seashell Mansion.
These are the type of "suprising rewards" I gather you are referring to that are missing now. Treasure chests themselves have always been money-oriented. What I'm sure you'll agree with though, is that we don't actually NEED the rupees as much these days as we used to. Money's easy enough to come by by cutting grass or killing something. (In "TP" I had to put on magic armor to burn money to even be able to keep the money I would find in a chest.)
