This is the best Zelda game I've ever played. The plot is simple enough to understand easily, yet gripping enough that you want to keep playing until your sword arm is tired. Which it might, due to the incredible use of the motion controls. Nearly every enemy in the game has a trick to beating it. One of my favorite parts of the game was nearly getting curbstomped by a Lizalfos, and then not 20 minutes later, curbstomping one myself, because my own skill with the sword had improved.
Traveling through the sky doesn't involve much combat. There are a few octoroks in the floating rubble who'll take shots at you, but they're easy to avoid. Skyloft itself serves a similar function to Windfall Island in Wind Waker. You can shop, and find a few sidequests. The sky is fairly relaxing, compared to the surface.
I only have one very minor problem with the game, and that's with the Final Boss. His appearance, behavior, and name all seem to scream "Most Awesome Boss Ever". I fully expected this to be a final boss battle which would fit with the rest of the game's "Smart Combat". Unfortunately, he was rather predictable, and easy to counter once I saw how. This is only a minor flaw, as he was still difficult; he deals a lot of damage, and I only won because I thought to bring a couple of potions. Still, I expected a more interesting
I can't help comparing this game to Twilight Princess. The main difference seems to be that while TP emphasized the conflicts - Zant's invasion, the Holy Shit Quotient
in the boss battles, Ganondorf's execution scene - Skyward Sword places slightly less emphasis on that, and a little more on the people Link meets. The conflict is still there, but we see more of Link's friends and allies, even having The Rival
play a crucial role in the plot.
In the end, this game is great in most areas, and nearly perfect in others. The only thing keeping it from a perfect 10 in my book is the lack of a cerebral challenge in the Final Boss, when it was so common in the rest of the game.
