Not only the best Zelda, but one of the best games period.
This 2-D Zelda had it all. From brilliant dungeon design, the numerous and different items, and a huge world to explore, A Link To The Past will be a game that will never die. This game is an adventure game where you take the role of Link, and hack and slash your way through multiple dungeons across two worlds, all to save a princess in distress. The dungeon designs are excellent, each which will make you think. All of the items are useful and handy, and there are plenty to choose from. Plus, the world is just beautiful to explore.
Graphics:
For their time, they are amazing. Heck, even today they look great. The landscape, the castle, the dungeons, the characters, all are rich with detail and bright colors.
Sound:
Some of the best music is any video game. Period.
Replay:
I've owned this game since 1992, and probably play it through at least 5 times a year. Does that answer your question?
Overall:
A must own. If you like video games and don't own this game, you're an odd one. This is a game that should be in everyone's collection, whether or not you still have the system to play it on or not!
