Is it just me or does this seem like stating the obvious? Of course Ocarina of Time isn't very good from a technical standpoint when you compare it to the games of today, but then again, what game is? Sure, if people played Twilight Princess before Ocarina of Time, they probably wouldn't like it as much. But I'll bet they'd still play through the game, because it is entirely playable today. There wasn't anything technically wrong with it when it was first released, so there isn't anything technically wrong with it now.
Aonuma is delusional if he thinks he can create something with as big change as Ocarina of Time, sorry to be so blunt. Going from 2D to 3D was a huge change in and of itself, and if you think about it, the game really isn't much more than the 2D Zelda games in 3D. If it had a top-down perspective then I'll bet almost all of the game would still be playable. But switching to 3D added a new perspective to the old which made it new and exciting once again. A switch like that happens only once in a lifetime, we're never again going to experience anything that is such a dramatic change.
