I am loving Zelda so far. Skyward Sword. I can agree with a few things that he said, and disagree with many more.
The helper has to go away. I even long for the days of even navies saying "listen" , compared to this person that I do not even know the name. Walls of text that I cannot skip. Also having to do set objectives before I can move on is and has annoyed me since Majoras Mask. If I spent another hour in clock town doing all that crap just to leave I was going to flip out. Enough is enough let me be free already Nintendo.
As for the sales of SS I think Happy Dolphin is right that this has happened before. Plus the Wii is about done. I am not sure, but I think some were not willing to get it just because they were not too sure about the motion control. Why take a chance and re-buy a wii when the wii is about done? I do not really know, but that could he some of the reason for sales other than the wii is in it's twilight.
SS is a good game though. I have had no motion control problems, love the atmosphere, is challenging for me (I do not play a ton of games so that is probably why), and I have just had a fun time playing it. I know what the guy is talking about, but maybe Nintendo thought a harder game would not go over to well with current Wii demographics? It would be nice to b able to explore and have an adventure. The way it is now is basically a Mario game, except you do not have to go from world to world. You still need to follow a certain path though.
I really enjoyed Shadow of the Colossus. You can just go do whatever you want. Now the content in the game was not anything like you would see in a Zelda game, but you were free to go anywhere and explore. So that seems to he a goood example of what I would want in future games.
