A lot of people were initially turned off by the cel-shading, myself included, but the minute I began playing it, I forgot all about that. The cel-shading added something that wouldn't have gone with any other of the Zelda games, but worked with this one because of the tropical theme. It was completely stylized, a first for a Zelda game. Some of the graphics (but not all of them, of course) surpassed those of OoT, as in the room of Hyrule Castle where the stained-glass windows depicting people like Saria, Ruto, Impa, Darunia, King Hyrule, Ganon, and others were The gameplay was also incredibly excellent, and continued to get better, and the dungeons were just as hard as OoT's, and I appreciated how much effort went into making them as difficult as they were. The only problem was that I felt the game was too short--five dungeons wasn't enough, even though there were many small dungeon-esque areas full of problem-solving. I also was not a fan of how huge the overworld was...even with the aid of the Ballad of Gales, it took much too long to get most places. Otherwise, it was perfect.
Still, in my opinion, OoT > WW, just because of the realism and story.
