I found Wind Waker to be an excellent game. If you ignore your own insecurities about playing a 'kiddy' game, you see how very detailed and life like the game's graphics really are.
When I first played Wind Waker, the first thing that came to my mind was how life-like everything was. The swaying of the grass to the wind, the waves in the ocean, the birds, the clouds, the caves. Everyhting aobut it was brilliantly done
Windwaker even added a little somehting to the combat system of Zelda, with the parrying feature and the various uses for weapons.
Anyone who hates Wind Waker because it's too different from the Zelda they're used to, shouldn't consider themselves a fan of Zelda for being so ignorant
