It's the very definition of eye candy. Like Okami, this is a game that's just as enjoyable to look at as it is to play.
Cel shading is so 5 years ago, but Ubisoft has packed a ton of little details into the characters and environments and coupled them with "normal" texturing. The end result is breathtaking. I want the next Zelda to look like this.
But other than that, this is just a really, really good game. It's actually challenging Mario Galaxy as my 2nd favourite game this gen (you can probably guess the first >_>)
So yeah... buy it! :3
