Skyward Sword is really not worth playing. There's a lot back tracking in the game with you going to a lot of places you've been before, you have to go to three major zones about three time through out the course of the game. The overworld is like Wind Waker if it were set in the sky but the problem is that there's nothing to do but go from point A to B and there's no interesting encounters and very few islands and it's ends up really barren. Another major thing is the gameplay is surprising hard for a Zelda game which might have been a good thing if it were not for the sword play that's hampered by the Wii's motion controls which you have to almost constantly recalibrate.
So I recommend not playing it and instead watching an LP of it if that your kind of thing, otherwise don't play it. The only goods thing I can say about it is that it's challenging and it also has some fun characters with the villain Ghirahim and Groose who is basically the LoZ version of Gaston.
Skyword Sword really bothers me. I read somewhere about how Nintendo will come up with a game concept before assigning a franchise to it, and Luigi's Mansion started out as a Zelda concept. I have no idea if this is true or not and I don't really care, but it got in my head and now whenever I play SS I feel like it should have been a Mario game because for some reason that's what it feels like to me. It barely seems like a Zelda game at all.
Probably not controversial but I think video games are an unproductive waste of time; although they would be far from the top of the list, I would rank things like "shitposting on forums" and "reading news article comments" above video games if I were like making a list of productive things to do with my free time.
