I guess it's time for me to contribute to this.
I haven't played many LoZ games. In fact, I've only played two: OoT3D and Four Swords. And I have to say that OoT was one of the best games I've ever played in my life. Simple as that. Although I haven't had the chance to play another Zelda game since I finished Ocarina's Master Quest for the second time, I have delved into the world of the game and have done my study of the timelines. Admittedly, I don't really like the timeline split. It makes things too complicated, and a bunch of Zelda games seem to have been just thrown in, making the continuity inexistent in some cases. But despite that, I generally like the whole theme and idea (although having a Link or two less wouldn't hurt).
The music of the games was a surprise for me when I first played. Rarely have I witnessed better soundtracks. The Song of Time and Ganondorf's piano theme have to be two of my favorite soundtracks. Especially Song of Time...
