One of Nintendo's biggest and most popular series, The Legend of Zelda is a fantasy action/adventure set in the kingdom of Hyrule. As the legendary hero, Link, you have to wander the land, fight monstrous creatures, explore maze-like dungeons and solve puzzles in order to rescue Princess Zelda from the evil Ganondorf.
The legend itself is a puzzle. You are not always playing as the same "Link", but as a lineage of characters called Link who acquire the Legendary Hero name, which is tied to the Triforce and the Master Sword. To this day, fans are still trying to unravel the legend.
