For a big Zelda fan like me, this kind of retrospective really knows how to press the right buttons. :) Pun intended.
For 30 years, this game has redefined the action adventure style and it all started with a golden cartridge, yes, a gold cart with a save-game battery inside. The first to explore different colours on the Nintendo NES and the first to offer a save game feature.
Forget about those Metroid pass codes to restore your progress, you could now load the game like you open a Word document today. This was quite a revolution.
