Did you look at the maps? How could you possibly get lost in TP, or any 3D Zelda for that matter? The path to Death Mountain is a very narrow practically straight corridor. And even if you want to include Hyrule Field, every path but the one you need to take is blocked off and the only thing special about it is that it's wide. Plus, again, in previous games you had a minimap always on screen. You can explore off the critical path and find stuff like heart pieces in Eldin Volcano, too... You can find 2 pieces of heart on your way to Death Mountain in TP. You can find 2 on your way to the Earth Temple in SS in Eldin Volcano. Lots of goddess cubes, bugs, and crafting materials to find, too. And that's not including the sky, which has stuff to find and sidequests to complete. What's stopping you from poking around Skyloft and helping people for rewards?
Fi could have just told you to go to the summit, but how would that not be worse? That's literally telling you where to go and not giving you any choice to find out for yourself. The premise is that Fi and Link do not know where to go and if they want a hint they can use the optional dowsing mechanic. If the game holds out it's hand don't complain because you reached out and grabbed it when you had the choice not to.
Sorry. I didn't mean lost as in "I don't know where to go." I meant it as in "I can wander around and head nowhere in particular." I should have clarified. SS doesn't let you do that on the ground. You can in the sky, but there's just not enough to find there for a space that's so large. And yeah, TP isn't great at it either, which is one of the reasons why I dislike that game.
Dowsing tells you where to go too. They both tell you the exact same information, but by having Fi say it you could at least remove the mechanic that doesn't add anything. I don't think either is a great answer, but I think my suggestion is better than the one the game gives you. I'm not complaining that it's optional - I don't think it should be there at all.
In order to illustrate my point, let's take a place from Majora's Mask. I'll choose Southern Swamp, since I think it has the
least amount of things to do. I'll point out what you have to do, and then point out what's entirely optional. MAIN PLOT AND SECRETS SPOILERS FOR MAJORA'S MASK. If anyone's reading this and hasn't played MM, don't continue reading.
What you have to do in the area: Talk to the hag in the potion shop, and find out her sister is missing. Go into the Woods of Mystery, follow the monkey, and find the sister. Go back to the hag, get the potion, and bring it to the sister. Go to the tour center, take the boat to the Deku Palace, find the plant seeds, water them, navigate the Palace, try and rescue the monkey, learn about the Temple and get the song, make your way to the Temple, learn the Song of Soaring, open the Temple. There's no marker for any of this, you take clues from dropped dialogue, and have fairly open spaces to navigate.
Now here's what's optional:
- Piece of Heart in the tree on the way to the Tour Center
- Shooting Gallery down a non-required pathway; prizes are a Piece of Heart and a Quiver Upgrade
- Pictobox, by talking to the man running the photo contest
- Maps purchasable from Tingle
- Prizes for photo contest. Usually Rupees but you can get a Piece of Heart by taking a picture of the Deku King. As a secret, you can also get it by taking a picture of Tingle.
- Piece of Heart in Deku Palace - gotten by dodging Scrubs on the ground.
- Get a Title Deed by trading with the Deku Scrub at the Tour Center. Part of a trading chain.
- Piece of Heart from using that same Deku Scrub's spot to get onto the roof of the Tour Center
- Great Fairy Fountain near the Temple. If you find all 15 stray fairies, you get an upgraded spin attack.
- Piece of Heart near Temple, on a random rock that's up to you to find.
- Skulltulla House. Complete it and get the Mask of Truth.
- Two frogs in the area (one in the Temple), that you can talk to with the Don Gero's Mask. Part of a chain to get a Piece of Heart.
- After the Temple, the Butler's race. Complete it to get the Mask of Scents.
- Using the Mask of Scents, you can find mushrooms in the Woods. You can use these to get free potions.
- After the Temple, the Boat Cruise turns into a shooting minigame, giving you the chance to win a Piece of Heart.
ALL of that is completely optional, and the majority of it isn't pointed out to the player other than a dropped hint here or there. You can find them by just poking around. And that's just ONE part of the game world. There's three more compass directions, Romani Ranch, Termina Field, and Clock Town. You can see that the sheer volume of things to do in this one section completely outdoes any one section of Skyward Sword. And again, I chose an area that I think has the least to do and find in the game. What does Skyward Sword give you? Drop materials for beating monsters? Is that really something that I had to find on my own? No, the game throws them at me, and can't shut up about throwing them at me.
Majora's Mask has exploration and things to find in spades, and crushes SS in that regard. And none of it is given a marker - the player has to find them on their own. Skyward Sword not only forces you along a path with almost nothing else to do, it shows you the path that you're forced to walk along. MM lets you explore each area; SS doesn't let you deviate from the main path and then tells you where the main path you're already on is. If I'm in the Southern Swamp, I can spend an entire cycle in a shooting gallery, or taking pictures of random things to get rupees, collecting up to 3 Heart Pieces lying in the open, or whatever I want before continuing on the main quest. If I'm in Faron Woods, I have 1 Piece of Heart, and 2 Goddess Cubes before continuing on the main quest, and both Cubes are thrown at you. Please note, in the past two sentences I'm detailing things I can do before reaching the dungeon. After I've reached the dungeon or completed it, Southern Swamp proceeds to crush Faron Woods in terms of things to do, and it's a fraction of the size.
