3. The Key

First Appeared In: The Legend of Zelda (1986)
Ok, so needing a key to unlock your apartment door isn’t all that revolutionary. But Shigeru Miyamoto & co. must have spent plenty of time losing their keys, because they’ve always forced us to hunt down way too many of the tiny things on our treks through Hyrule, when we would much preferred to use Link’s cool sword-laser and blow a hole through the wall (ever notice that never works?). And these days? Keys are cool, so cool that Fable III<.i> has an Xbox achievement for—wait for it—finding every single key in the game.
