Sigh..
OoT is a port. It added a boss challenge mode and nothing to significantly enhance the gameplay or add more replay value. No matter how much you think they improved the graphics (FYI, they added polygons to the old models and didn't create new ones from scratch) or the sound (they literally did nothing but sequence the music so it sounded exactly like the original, crappy N64 music), it ultimately was the exact same game with a couple of minor tweaks to how items are equipped. Oh, and breathtaking, gameplay-enhancing 3D. Joy.
If you honestly think their aim with OoT 3D was to remake the game from the ground up and improve upon in it substantial ways, I can give you Ask Iwata quotes that show otherwise.
This is a remake:
Thought at first glance it looks the same game as the NES version of Super Mario Bros., play the game even for a few minutes and you can see that the programmers dug into the original code of the game, fixed many of its flaws, and added new gameplay features. It wasn't rebuilt from scratch, but it was improved so much that it stands on its own as a new version, not port, of the game.

THAT is what Nintendo is capable of when they set out to properly remake something. OoT was kind of lazy.
