"The question that often comes up when discussing The Legend of Zelda is "does link need a voice?" Well, no, he doesn't. I like the idea of keeping Link as a voice-less hero because it's easier to imagine yourself in the world of Hyrule. That said, the game does need to take a nice big step in the right direction in terms of story telling and character development.
The first obvious change that needs to be made is the inclusion of voice acting. I know, I just said Link should keep this trap shut, but that doesn't mean that the characters around him can't speak. Zelda games always provide the player with an epic adventure, however reading text brings you right out of the experience. It's time to get with the times, Nintendo."
