I've been playing it and the graphics are so much better compared to the N64. I don't have the 3D effects on (I don't have a high tolerance for them to begin with, but I turn it up when I get a new item (looks cool when Link holds it up) and during cutscenes.
The controls have a slight learning curve but you get used to it easily. Some notable changes are that the Iron Boots and Hover Boots aren't on the Gear page but can be assigned to "C buttons" (like the Iron Boots were in Wind Waker and Twilight Princess). The "C buttons" in this are the X and Y and 2 touchscreen buttons (called I and II). I usually have the Longshot and Bow on X and Y and other items (boots, Lens of Truth, bombs, etc) on I and II since they're not used as frequently.
The Water Temple is slightly easier since the pathways to the markers to raise the water are noted as are the height the water will change to. Fishing is harder (or more frustrating).
The Ocarina is on a permanent touch screen button in the bottom left. You can play songs with the touch screen or buttons. What's really good is you can have the songs notes on the bottom screen so you don't have to memorize them. What I didn't like was I couldn't memorize them well. I know what all of them are on the N64 but the button layout didn't translate well to the 3DS. For example, Zelda's Lullaby is LURLUR on the N64. On the 3DS, it's XAYXAY (if they were C buttons, it'd be URLURL). But it doesn't hurt the game itself.
I actually read a really funny comment on GameFAQs. Someone complained that they went from the Shadow Temple to Ganon's Castle without saving. They shut it off and resumed at the Shadow Temple. Stupid kids so used to autosaves in CoD.
guys, i registered my copy of Zelda OoT 3D today, will i get the CD? I mean, i bought the game from Amazon, on release date, but i was only abloe to register today, so will i get the music CD?
Those who registered it by 6/20 were guaranteed to get it. After that it's first come, first serve. I wouldn't count on it. But there will be torrents up online later.
