To be honest, I thought the game was really great. Taking anything away or adding something to it would ruin the experience.
Gameplay
I was very fond of how WW was played. Sailing was a great experience, it really added to the feel of a true adventure.
As an expansive overworld, the Great Sea is full from many surprises. From unexpected maritime battles to being sidetracked into salvaging treasure, it really speaks for itself. Exploring islands for anything was truly an adventure of its own, for you wouldn't know what secrets lie within.
Off the boat and onto land, glorious action and amazing experiences are still found. Who could forget the fighting?
The revolutionary Targeting System seen in OoT and MM was brought back for this third 3D installment. Link found himself with new fighting techniques and more complex sword combos. He could take on large hordes of Moblins and Darknuts with the skills he held. This really added to the experience.
The controls for the game were very smooth to me, perfect action each time. I'd give the gameplay 9/10.
Graphics
WW dipped the Zelda series into a cartoonish and colorful cel-shaded world.
While some rejected the new style of graphics, I personally adored it. The bright colors and interesting themes brought the game together. I'll keep it short and sweet: the graphics were wonderful.
For them, they get an 8/10.
Story
The plot off WW branched off from the Adult Ending of OoT. With the parting of the Hero and return of Ganon, disaster struck.
After the events of the Great Flood, Hyrule is submerged under the tides. It goes on to explain the traditions of Outset Island, and shows how Link eventually became a true Hero. From the simple aspect of a kidnapped sister, the story complexes to the terror of Ganon and the mystical Wind Waker. It goes on even further to show that Link must obtain the Master Sword, assemble the Triforce of Courage, and ultimately save the Great Sea.
I was very favorable of the story. It gets a 9/10 in my book.
Music
This is what really tied the game together. With an excellent soundtrack, it felt as though that you were actually in the Great Sea. The dungeon tunes, the theme of the Great Sea, and many more compositions really makes the game what it is.
10/10 for outstanding music.
Overall, it's a 9/10 for me. There'n nothing that I could see that would make the game better, for it's great how it is now.
