The sidequests were the best part of Majora's Mask. It made the world a lot more natural and real than Hyrule in OoT. The entire Kafei/Anju sequence was one of the most emotional and dramatic moments from any game I've ever played. I didn't feel as though I'd accomplished nearly as much at the end of OoT as I did at the end of MM.

A Link to the Past was gold. Well, figuratively. The cartridge wasn't gold, which sucked. Wind Waker isn't quite as open-ended as you might think, considering that the dungeons are sequenced very specifically. Although there is a lot of exploration and extra side-quests to be found. I spent probably somewhere around five hours just sailing and filling out the rest of the map, and loved every second of it.

AoL was actually a pretty cool game. I got the Collector's Disc and have been playing back through it. I'd forgotten how insanely hard the game is though.
