I think one problem that the game faces that it has no control over was the fact that it was announced over 2 years before it was released. Twilight Princess comes out in 2006, and then Phantom Hourglass in 2007. We get nothing for a long time except Spirit Tracks, but for about 3 years, we get nothing about the next big Zelda title. Then we got an image Link and Fi (back then as a mysterious figure), getting fans all hyped in E3 2009. Then in 2010 that the game was going to be out before the end of the year, and then E3 2010 came and we get just a little bit of the trailer, which threw many fans in excitement and a little bit of distaste at the art style (many thought they were going to be more realistic and not be so cartoony still). And of course, they revealed it was going to be out in 2011. Then a Nintendo Direct or whatever in early 2011 comes and we get a bit more of the game's gameplay, but still no plot. Finally, at E3 2011, we actually get a better glimpse of what the game will be like and what the plot will be like, and we find out it will be released Holiday of 2011. Finally, in November the game came out.
But it was kind of like "we really know nothing about the game, and yet it took them 5 years to get the game out." The advertisement of the game was a bit of a letdown, and then a few months after the game comes out, they make an awesome trailer that we would have rather had before for the game to come out. This game took a long time to come out, and it kind of felt like we didn't get to know the game well before it came out. I mean, Twilight Princess at least kept us updated a lot about the game and what was in store, and the first trailer at least helped give us some plot stuff rather than Skyward Sword waiting till the final months to give us some plot stuff. I know that Skyward Sword was heavy on the gameplay mechanics with the motion control, but I think that them keeping the plot stuff low really made it hard for people to know if they wanted the game or not.
I think this is parallel with the Wii U. We find out about the Wii U in 2011, and how it's the next console for Nintendo. We see the awesome features with both handheld and console gaming put into one, and how they will really intertwine together. However, between E3 2011 and E3 2012, we hear not even a pindrop from the Wii U's update. Lots of rumors that the Wii U was cancelled, or that it was going to get a complete overhaul or something like that. Then, in E3 2012, not only did Nintendo say they were going to continue with it, they were releasing it this holiday season. And then we didn't even know for how much or the exact date until September 13th (iirc). That was literally just a little over 2 months before it was released! I think one of the biggest problems the console faces was the fact that we barely get anything off of it, lack of advertisement, and then next thing you know, it's coming out with many people still questioning this system.
I know, this is about Skyward Sword, but all I am saying is that the sales of Skyward Sword as well as the fan reception could have been better had we been better prepared for the game. I think most of the controversy about this being not that good of a Zelda game comes from the fact that we had little detail about this game. I mean, great for people that don't spoil themselves, but a little hint at what we are getting is better than nothing at all. I mean, there are games like Pikmin 3 and Wind Waker HD that they constantly inform gamers about what is entitled in the games, and guess what? They will/are selling excellently! I mean really, Pikmin 3 made the Wii U sales go way up, and I have a feeling that the Wii U's sale will also get a big hit in sales with the Wind Waker HD's sale.
My point is, Skyward Sword would have been much better had the game been better advertised, and it is one of the things that Nintendo needs to work on with their things so that not just some games get good advertisement while others are left in the
