I've been playing it a lot and I'm a little over halfway done. I've 'spoiled' myself a little bit, but I won't do that to any of you.
I am deeply enjoying this game, of course the game is extremely fresh to me, but there are so many aspects of it that I like better than OoT.
The biggest downside of this game has been well stated by IGN and other reviewers and I found I agree... not as many dungeons as there was in all the previous games. Each dungeon by itself is better than the other dungeons from previous games (Guys, I thought the Water Temple from OoT rocked, especially fighting Shadow Link!) but they are fewer. Granted there is more worldly exploration, until you get into the later part of the game you have no idea how much, which is just almost as good.
The one thing that I am very happy with is: I like to 100% complete RPGs that I play and there is a ton of stuff to collect and do in this game. Also, Nintendo did with WindWaker what they did with M

rime... when you beat it, you can play it again on a harder mode, only with WW some things are slightly different (but not nearly as different as Master Quest OoC)
I could talk for hours about Zelda, but I'll spare everyone the boredom.
Have fun,
