I've spent more than 60 hours in this game, so I think I can say that Skyward Sword is one of the best Zelda games ever seen. The art style is just gorgeous, everything leads you to explore and complete every single thing. I haven't felt this way with any other Zelda, and I've played Ocarina (which I loved, don't get me wrong), but not even Ocarina, which is marvelous, could make me fall in love this hard. Also the music, the story... It's 10/10.
If I have to say something bad, I think the controllers are hard to play with. I played the Switch version, so I had the option to use only buttons and that's the way I went once I got tired of trying to use the joycons and having to readjust them every 30 seconds. The only buttons mode was a life improvement of 100%. Also, it's true that 60 euros/dollars is expensive for a game that was released 12 years ago, but well, I bought it for 40 euros because it was in discount on the eShop.
If you're curious about this game but you're not sure of buying it, try the Switch version. Trust me, you won't be disappointed.
