Bow before the mighty Javoo!
OoT and Smash Bros!
Super Smash Bros. It's in my system right now.

With friends I definitely second this pick. 4 player Alcatraaaaaazzz! \ ^_^ /
Solo, though, my favorite is probably Tetrisphere (at the very least, its what came to mind). I really love most of the music in the game and it was always a title I could pop in and chill out to while playing. It was especially nice late at night or early in the morning when the visuals really popped out in a dark room. It's also always one of the first titles I make sure works on whatever emulator I am using.
I don't really have a favorite. I guess maybe Ocarina of Time wins, but I also loved so many other titles in their own way.
Majora's Mask, Super Mario 64, Shadows of the Empire, Smash Bros. Man, fun times on that console.
