Well so far I've played about 10 hours of Zelda: Skyward Sword. And I gotta say, I'm loving it. Its like they took the style and design of the 2D games and put it into a 3D world. And even after just a short time, I've come to enjoy the characters in this game more than Majora's Mask, Wind Waker and Twilight Princess combined.
The one area the game seems to be lackingis there are still a lot of 'fetch quests' in between dungeons. But even then, they're better than the ones in Twilight Princess by far and you have a lot of fun activities to do in between to give yourself a break.
In short, I'm loving this game so far. We'll see how the rest of it goes.
