Twilight Princess is nothing short of an amazing game that you shouldn't miss out on.

One of the huge advantages the Wii version of TP has over the GC version is how you swing your sword. Rather than just pressing a button, you swing the Wii remote left and right to swing your sword accordingly. You can also swing your nunchuck to perform a spin attack. Using the B button, along with the left, right, and down directons on the D-Pad, you can use different items that Link (your character) picks up on his journey.
You start of in Ordon Village, which is your hometown. A series of events leads to you chasing after three of the village children, as they chase after a monkey that's been vandalizing the village. At the end of your chase (you've already met up with two of the kids), you find one of the kids trapped in a crate along with the monkey. They're surrounded by monsters. This is just a small part of the many trials and events that Link must go through in order to complete this game.
In most of the Legend of Zelda games, the main character is Link, Zelda, or even Ganon at times. In this game, the main character is actually Midna, who is infact the Twilight Princess. As you advance through the game, the story seems to reveal Midna's true self more and more until at the end of the game, she returns to her true form as the princess of the Twilight Realm.
Midna is also a key help in this game. When you first meet her (as a wolf), she decides to help you. Basically, Link's world has been blanketed in Twilight and he's determined to stop it. But what's Midna getting out of this you ask? Fused Shadows. The weird fixture on her head is one of them, and within the next three dungeons lie the other three. As you could've guessed, the bosses of said dungeons hold the Fused Shadows.
But that's enough story telling for now, onto the many other features of the game.
The dungeons in Twilight Princess were created with the right mind set, but the difficulty level just isn't there for most of them. The first dungeon that I really had trouble with was the City In The Sky dungeon, which is the 7th out of 9. Unfortunately, the two after that were hardly long enough to be considered dungeons. That's not to say the previous dungeons were boring because of their lack of difficulty. As a matter of fact, my favorite dungeon was the second one (Goron Mines). While you didn't have many weapons, hearts, or in-game experience for that matter, it was still a fun dungeon to trudge through.
Chances are you'll be playing as human Link throughout most of the game, but the Wolf form plays a big role as well. For the first three dungeons (those Fused Shadow dungeons I was refering to), you have to play as Wolf Link first and collect the Tears of Light from each area. If you do so, the Twilight will be lifted from the area so you can play as human Link.
Howling Stones also play a role in this game. If you come up to a Howling Stone as a wolf, you'll hear a melody and have to howl it back to the stone (kind of like when you learn a melody in previous LoZ games). If you do it correctly, a Golden Wolf will tell you to meet him at a certain location once you become human again. That location will be marked on your map. When you do see the Wolf as a human, he will teach you a skill. There are 7 hidden skills in total, and each one will help you in different circumstances. Some enemies can only be defeated using certain skills. I think these skills really added to the game, to help make sword fighting less repetitive.
Puzzle solving is also a big part of this game, as in most Zelda games. Like with the dungeons though, most puzzles were pretty easy to solve, and only had you thinking for a minute or two at a time.
Since the world of Twilight Princess is so massive, warping is also a big part of the game. In certain parts of the game, it will randomly skip to a cutscene (I call them warp-scenes) were you see a hole form in the sky. Out of the hole will come shadow beings, which you have to kill. Once you do kill them, the hole will become a warping spot, so you can return there whenever you please.
One thing you would expect more of in a game this massive, would be sidequests and minigames. One of the minigames is the 'STAR' game, which can be found in Castle Town. The goal of the minigame is to collect these glowing orbs that are scattered around this cage. To complete this game you'll need the Clawshot. The first time around, the man who runs the game will give you the Big Quiver, which holds 60 arrows. If you come back, the man will have a second version of the minigame in which you will need the Double Clawshot to complete. If you do complete it, the Giant Quiver will be yours which holds 100 Arrows. Iza's Rapid Ride, is another minigame. When you first find Iza she'll say it's closed. But once you walk away, one of the warp-scenes I told you about will occur. After defeating the shadow beasts, Iza asks for your help. Thanks to an avalanche, rocks are blocking the river rapids. Iza gives you a bomb bag full of bombs, and presumably a bunch of arrows (since you have an unlimited supply for the time being). Using bomb-arrows, you need to clear out the rocks so that Iza's Rapid Ride can re-open. If you do it successfully, you'll be able to keep the bomb bag once you're finished (this should be your second bomb bag). If you go back and play the minigame, every one of your bomb bags will double in size when you win.
Wait, did he just say second bomb bag? Yes he did. As a matter of fact, there are three bomb bags available in this game. The first bomb bag, you can buy at Barnes Bombs in Kakariko Village. I've already told you how to get the second bomb bag. And the third bomb bag can be found when you bomb a rock at the bottom of the Royal Chamber in Zora's Domain. But how did you use a bomb under water, you might ask? There are also three different kinds of bombs in this game. The first, would be traditional bombs. The second, would be Water Bombs. These bombs work the same way as regular bombs, but can also be used underwater. Lastly, there are bomblings. Depending on the direction you place the bomb towards, it will walk until it either explodes or hits something.
But these aren't the only new items in the game. Also making it's first appearance in Zelda games is the Double Clawshot. This adds a Spiderman sort of feel to the game, as you can grapple onto consecutive things without touching the ground. There's also the Hawkeye, which allows you to zoom in on your prey before making your move. Also, when you attach it to your bow, you can shoot things at a distance with more accuracy.
Two other sidequests in the game are collecting bugs and poes. Bugs, more accurately known as golden bugs, can be found all around Hyrule. If you catch them and bring them to Agitha (in Castle Town), she'll reward you. When you bring her your first bug, she'll give you the Big Wallet, which holds up to 600 ruppees. With every bug after that she'll give you either 50 or 100 ruppees. Once you give her every bug (24 I believe), she'll give you the Giant Wallet which holds 1,000 ruppees.
Poes aren't as easy to collect as bugs though. When you find a poe, you'll need to transform into a wolf and use your sense instinct to attack it. When you defeat a poe, you'll get the poes soul. Bring those poe souls to Jovani (you'll need 20 for your first reward), and he'll reward you with an empty bottle (one of four).
While not a large part by any stretch of the imagination, fishing does at least play a minor role in the game. While bobber fishing can be done anywhere (with your fishing rod), lure fishing can only be done at Hena's Fishing Hole. To fish, you simply hold A and swing the remote foward, as if you we're really fishing. To reel your line in, just rotate the nunchuck. If you crave action, fishing probably isn't your thing, but if you don't mind relaxing a bit then you'll probably enjoy this part of the game.
Twilight Princess for the Nintendo Wii, is certainly the best game they've released for it thus far. Personally, I also think it's one of the best games in the series. Ocarina of Time is my favorite game of all time, and while playing through TP I thought it might have a chance at being de-throned. But after completing TP and looking back at the two of them, I've learned that TP, nor any game that I can think of, will ever be the OoT like game we expected. But TP is still one of the best games I've ever played, and certainly worth it's $50 price tag.
