Goddess cubes and chests are the same as sea charts and underwater chests in the WW.
I agree with this, and I think it should apply to SS moreso than TWW (I don't agree with not getting all treasure charts since they're tracked in the menu)
I disagree with only getting 1 of each medal though, just because it makes sense to me to have all 20 hearts on display and you'd need both of the Life Medals, so why would you require both life metals but not the duplicates of the other medals, even if you aren't going to use them? I feel this way about the bottles too, even if we don't use them we're grabbing every duplicate of THAT item, so then why aren't we just collecting 1 bottle?
Goddess cubes are confusing to me, since it doesn't make sense to hit a cube and activate a chest that is going to sit there on the map and do nothing with it. So if we're on the ruling of having to collect all the cubes, then I'd also feel that opening all the chests would be required as well, as dumb as that is. I feel the same way about the dungeon maps too, since dungeon maps show which chests you haven't opened I'd feel it necessary to open those chests as well.
I actually agree with getting all the dowsing targets just so it would fill the slot, even if we don't ever use it..
I think upgrading items is really stupid, personally. I think if we have to include it, that it should just be used for items like the bug net, beetle, etc. B-button items.
Disagree with buying the satchel/quiver/bag for upgrading, that honestly feels to me exactly like buying all the shields to upgrade them, or buying options just to upgrade each one to the highest status, it's just stupid. But in the same sense they're linked to your B-button items so it seems weird that we wouldn't upgrade the ammo count as well as the item itself... :/ I just think upgrading is dumb.
Then there's Treasures and bugs, which I don't think has been asked about. It makes sense to me to collect at least 1 of each bug/treasure to fill that slot on your status screen. But hero mode carries that data over from normal mode, so most likely all of these slots would be filled when you start hero mode, so would we still require the person to collect 1 of each bug/treasure?
And saving at each bird statue blah blah fills map space blah. Just throwing stuff around.
Edit:
@ goddess cubes -- small note. the game actually does tell you on the pause menu how many there are left. view info for the cube dowser. I'm not sure if it also counts the chests though (they can be dowsed for too). Make of that what you will but they DO appear on the pause menu in some fashion.
Well this changed my opinion on whether or not we should get all of the cubes, which now I think we should just based on that.
Double Edit:
Yeah I can't find it, I'm selecting the goddess cube dowsing on the status screen and it's not giving me any numbers, just what it does <_< is there a video showing the cube count or something? (I'm on a file that doesn't have them all collected, in fact there's one right in front of my face right now)
