They're all great games! Odds are you'll mostly play Zelda 1 and Ocarina, though. Zelda 2 is hit or miss for a lot of people (although i'm a huge fan lol) and Majora's Mask port is held together with scotch tape and a prayer. A few crashes here and there can be okay, but because of how Majora's saving system works, the game suffers a lot.
