Link is a kid that lives in the Kokiri forest with other children and no parents, but he is the only one without a fairy, until one day. The Deku tree sends a fairy called Navi to visit Link after a nightmare where he sees a man with a black armor riding a horse. Once he wakes up he finds Navi who explains him that the Deku tree (protector of the forest) needs help. Basically you know that a wicked man called Ganondorf has cursed Deku on his way to conquer Hyrule and Link must stop him.
Your worst enemy... I mean your fairy Navi
This is what we see now
For the remake as well as the touch options they've improved graphics. And now we have pretty good graphics. Keeping the main atmosphere of the original game, characters are much better and you can see more details everywhere. Even more, first time I played this game I checked how powerful is the 3DS moving the game without problems. This is nothing new. we saw the same with Metal Gear Solid and the remake for GC, but this time we have the 3D effect.
During the game I've been switching on and off the 3D effect and is something you notice. Not only when you get a new item and Links hold it for you to see how cool is on 3D, you can notice is everywhere; walls, on the hill, holding and running with a chicken (feathers look like are going to hit you)... it's something curious and fun. It's a great new way to enjoy games. Also when you are on first person view you can actually move the console like if it were your own view, so moving the console up you will see what's up there, that's cool.
Music is the same as the original composed by Koji Kondo of course, maybe some arrangements but why to change the original soundtrack if it's perfect? The ocarina songs are classical melodies in game history among other songs as the Kakariko village or inside house ones. Also there aren't voices (as always) expect for the typical Zelda sounds; screams, moans, whispers, yells and laugh from most of the main characters.
The only new song in the game
The final conclusion is simple, it's Ocarina of Time, what else do you want? I mean, just for the nostalgia factor you should play it and you will enjoy it a lot since is still challenging and epic. The 3D effect and new graphics makes it much better and attractive. Although maybe we've been used to many new things to enjoy it the same as in 1998.
