1. A Link to the Past
2. Ocarina of Time
3. Twilight Princess
4. The Legend of Zelda
5. Majora's Mask
A Link to the Past has always been the pinnacle of Zelda for me, and perhaps gaming in general. I still have a tough time deciding between that and Ocarina, but LttP always seems to edge it out.
My Games of 2011:
The Legend of Zelda: Skyward Sword
Elder Scrolls V: Skyrim
Super Mario 3D Land
Uncharted 3: Drake's Deception
