If it isn't broken, don't fix it.
Gameplay:
Without a doubt, the gameplay in Twilight Princess is the strongest part of the game. Yes it's just like the other Zelda games, but that's what makes it great. The addition of the wolf form, and the special skills learned through out the game make it all the better.
Graphics:
While the graphics are the best seen in a Zelda game, they are not the best seen on a gamecube game. When you look at some of the Resident Evil games on the gamecube you see, in my opinion, what the gamecube is capable of. To me it looks like they didn't quite get there, but it still looks fantastic.
Sound:
Not much to say here. They really could have done much better here. Love the music, but full orchestral could have made it so much better. Yes, Voice acting would have been nice, but I don't miss it that much.
Value:
I honestly don't think I will ever tire of playing any Zelda game. These games are timeless. I still go back and play the 8 bit original. Not to mention Link to the past, and Ocarina, which are two of my favorite games of all time. And I'm sure I will add this one to that list as well.
So that's my review. It's what I think of the game. If you didn't like it, more power to you, but I consider it my favorite Zelda by far. Thank you for reading my review.
