The best game ever made, period.
Gameplay 10/10
The gameplay is revoluitonary because of it's interface and combat skills. It is easy to aim with the revolutionary "Z" targeting. You can use Z targeting everywhere but the final battle aginst the evil Gannon. You can easly have three weapons ready at your disposial with the push of a button. And you can change the weapons by pressing pressing two buttons!
Graphics 10/10
The graphics were excellent at the time. They are revolutanary for the time.
Sound 10/10
The music is different everywhere and fits the ocasion. Plus, Link's yells and stuff can echo and be muffled down if he is in a dungeon or underwater. A genious idea that inspired videogames!
Value 10/10
You are getting two worlds full of sidequests and minigames that earn you weapons. You are also getting the best video game ever created. I would not like to spoil the story line, but here is all I am saying: You have to go from 10 year-old Link to seven years into the future back and forth multiple times. You get peaceful Hyrule and enslaved Hyrule. Just buy a Nintendo 64 and Ocarina of Time from some place like eBay. It would be a very good investment.
In conclusion, if you are interested in playing the Legend of Zelda series, play this one first! If you have been playing any other Zelda game, then purchase this game!
