Think "State of the Art."
I was instantly engaged by the story, and the controls, and the music, and just about everything in the game. The graphics were amazing; It's hard to describe the feeling you get when you walk onto Hyrule Field for the first time and see Death Mountain and the castle in the background. The PS1 graphics were not as good in most games, and they certainly didn't pay this much attention to detail as Ocarina did. Link moves fluently and realistically (I think he moves more realistically in this game than in Wind Waker or TP) and it's easy to control him. This game got me mad a couple of times, but as I continued playing it, I got mad less often and started to get the puzzles much easier. It took a long time to beat, but the game gives you such a great feeling of accomplishment when you do.
Just about everything is perfect in this game. It is state of the art; not many games have come close to being this high of quality, not even other Zelda games.
