1. LoZ: Majora's Mask--it's a very dark and surreal game, and it's the most overwhelmingly atmospheric game I ever played. To boot, it's also a Zelda game, which is never a bad thing. That last dungeon was just epic.
2. Fire Emblem
3. LoZ: The Wind Waker
4. Super Smash Bros. Melee
5. SMW2: Yoshi's Island
