Pretty damn good
Gameplay: For its time this gameplay kicked ass. If this game came out now I wouldnt rate it as high. The freedom basically to go anywhere I wanted in a 3D Zelda enviroment was great. The other things to do such as visiting the villages and other areas, becoming an accomplished mask salesman, fishing, riding your horse, and just exploring added alot to this game. It will give somone dedicated countless hours of play and around 3 replays since you wont get everything done the first time you beat it. Theres tons to do and see and the story will keep you entertained all the way through the game. Overall its alot of fun.
Graphics: When the game was released the graphics were insanley good. Obviously by now its put away by Halo and other games like that in graphics. But even after 7 years since its release I still enjoyed the visuals in this game. THats why I give it a 10. Even with the lower technology nintendo was still able to deliver a great game visually. The lighting the little effect gave it a good atmosphere. Im hoping that Twilight Princess will deliver this in a more modern package.
Sound: You cant go wrong with the music in a Zelda game. I still enjoy the corny sounds of the original Zelda the best but the newer orchestral sounds of this were great. They set the mood well.
Overall this is a very good and revolutionary game. It pretty much opened the door for a style of sandbox gameplay that was not seen before. The freedom to do what you want when you want was not seen in the 3D realm untill this game. I highly recommend it.
