The Legend of Zelda: Twilight Princess

History
Legend of Zelda: Game Cube was first revealed E3 2004 when Nintendo showed a small group of people a "Trailer" to their new Zelda Game. When the Zelda Community found out, they almost exploded with excitement. Threads popping up on Zelda Forums everywhere discussing what the new game looks like, sounds like, even smells like. After 10 months of complete silence from Nintendo, a new trailer was finally revealed at the Game Developers Conference on March 10th, 2005 to an eager audience. We now expect there to be much more information coming from Nintendo about LoZGC because it is set to come out in the last quarter of 2005.

Known Information
Not much is known about LOZGC right now because of Nintendo's amazing veiling powers over all of it's major games. All the footage of the game we have seen is either from one of the two trailers that Nintendo has released. The other scenes we have seen are from a few magazines, such as Cube, and Nintendo Power. All we believe to have learned is:

- Direct Sequel to The Wind Waker.

- No voice acting.

- No GBA connectivity.

- You can fish.

- Art of Zelda shows her wielding a sword.

- Yes Link is rescuing Zelda & Ganon is a villain in the story.

- No official title has been decided yet.

- Combat will be different from Wind Waker.

- Chicken Gliding is back.

- In the beginning of the game, Link is a "cowboy". There is also a minigame to teach you how to ride.

- Tauro village impressions, great sense of realism, grand in scale.

- Horseback battles will be plentiful.

- Link is 16 years old when the game starts, but they emphasize that will "mature" during the game, whether this is just mentally or physically as well is not clear.

- The Village shown in the scans is the very first village in the game, called "Taoru Village".

- Controls will remain more or less unchanged from The Wind Waker, this includes the return of L-Targeting as well as Auto Jump.

- Game will be "two to three times as large as Ocarina of Time", with more than 70 hours of total game play (estimate, of course).

- The developers have aimed for a very realistic approach with the water, and there will be an underwater part of the game as well.

- Eiji Aonuma wanted the graphics for the game to be as refined as possible, which is why they didn't use the graphics from the SpaceWorld 2000 GameCube Tech Demo, featuring Ganon and Link.

- The amount of mini games in this game will, just as in The Wind Waker, be fairly large, and an example of a mini game is where you have to lead some cows in to a certain area while on your horse back.

-and more if you would like to add.
