Unlike the N64, Gamecube and Virtual Console Edition is the graphics and frame rate of the game has changed. It runs in liquid 30fps with new character models and textures around, even the city and houses were equipped me more details and life. The sound quality has however not really improved, which is basically all the same, because the soundtrack is still enthusiastic and really awesome ... anyway orchestral versions would have been nice. The 3D effect is really super successful, the only drawback is the motion control, because then you come in from the field where you see 3D if you are not careful.
Unfortunately, there is no new bonuses in the game, such as new temple, Side quests or items ... but there is still plenty to do. If one examines all together and play through the story you get loose 30-40 hours pure fun to be doubled again by the Master Quest.
No other 3DS game comes to Ocarina of Time also zoom only close. It's a must-have for those who like action adventure and Zelda.
