Legend of Zelda: Ocarina of Time is just simply put as a "Classic"
The gameplay in this is amazing. Right from the beginning of the game you can tell that this game is well made and is just an excellent game. Well made sword fighting and different items really contribute to its full value. Also the bosses are well made. Also the new Z-targeting is a nice addition while battling many enemies. I really dont have the words to describe it, but this game is just phenomenal in every area.
The graphics are beautiful in this game. With all the landscapes and different areas of the game show the N64's capabilities. You can even see some facial expressions on the characters while they are talking which really shows they have spent a lot of time on this game and truly the hard work pays off.
The sound is implemented successfully. The music in the background is done wonderfully which also contributes into making this game a classic.
All in all this makes this game a perfect game and is a MUST-HAVE for the N64.
