Alright, so, I know there's a lot of people out there who still haven't gotten Skyward Sword, and some even debating it's priority for their list of games, so I figure I'll toss in my two cents on the game.
The Legend of Zelda: Skyward Sword stands at the latest and much anticipated addition to the franchise on the Wii console, standing alongside Twilight Princess as the only canon games existing on the console itself. ((Not including virtual console games))
Skyward Sword is a excellent addition to the series that manages to stick close to the traditional Zelda feel that lovers of the franchise have come to expect, while still branching out into new and unique game elements that set this particular addition to the series apart from the other. Obviously the most notable being it's motion control.
Nope, it's not the randomly swing the wii remote to kill things that you remember from Twilight Princess. Skyward Sword makes use of the Wii Motion Plus in order to pull you into the game, you've always played from the perspective of Link, but never quite this closely. Draw your weapon with a flick of the wiimote and from there your blade will accurately follow your movements, making for an interesting combat experience as you try to sneak in hits to your opponents weak spots.
The dungeons themselves may be a tad bit disappointing to any hardcore gamers expecting something intense. You've got your usual zelda dungeon formula here, enter dungeon, wander, find keys, fight mini boss, find dungeon item, find boss key, use dungeon item to kill boss. Nothing really new or flashy here, but it's worked since the start of the franchise, and it's clearly still working, so why change it?
Recent additions to the zelda series have introduced elements of having a special transport to get you around the land, Epona of course being our original transport, and this element also applies to Skyward Sword. Your transportation in this game comes in the form of a large bird called a Loftwing. (yours being a rare color; red) Your avian companion will dutifully carry you all over Skyloft, your central hub of sorts for the game, at just a whistle. As cool as having the ability to soar through the sky may sound, it's rather disappointing when you realize the entire Skyloft community is within walking distance and there's very little of interest beyond it.
Your companion for Skyward Sword comes on the form of Fi, a spirit that inhabits the sword you carry through the majority of the game. Fi is an interesting companion in concept, but she lacks any real dimension and is blatantly without emotion or personality. Though the design is intentional, it is still somewhat off putting, and often times her advice and suggestions are more obvious than helpful. But after a while I think most people will take a liking to Fi in some form or another, as her Analysis, dowsing, and enemy identification features put her usefulness at a level far higher than a certain fairy. But in my opinion, she's no Midna.
The graphics of the game are a sort of marrige between the artistic styles of Twilight Princess and Wind Waker, creating a beautiful world in a style that is akin to what you'd imagine Ocarina of Time would look like if it weren't made of polygons. It's a matter of taste. I prefer the twilight princess graphic style, but I do have a certain affection for that of Skyward Sword.
Without spoiling the story for you, I will say that in the end, it ties so much of the series together and so many things suddenly make sense, that "Aaaahhhh..." moment you have at the end of the game is worth playing through itself. Despite a few minor flaws and issues, the Legend of Zelda: Skyward Sword is a unique and welcome addition to the Zelda franchise with a wonderful world to explore, an extremely involved combat system, a great story, and all the music you could expect from a masterpiece of the Zelda series. There's a few things I didnt mention here that are worth noting, but I think I've said enough. All-in-all, Skyward Sword gets a 9.5 out of 10 from me.
