You know, thats a fascinating idea...thats one of the things about the voice technology which I am wondering about. Ive never used it before, not even on PC so I dont know whether or not its possible to synch a game to respond to voice commands issued with only the pitch of YOUR voice.
I can feel where a couple of you stand on the whole voice recognition thing....in public at any rate. Most people dont like looking silly, myself included, although I know in reality no one really gives a flying pigs foot about who I am, and why im talking to my little box. Nevertheless I feel, provided the technology is up to par, such an aspect can really add to the ease of control in a game.
And that to me is really what the DS represents right now...I cant yet see the enormous new gameplay or new ways to play games it will provide but I can TOTALLY see all the ways it can ADD to our gameplay experiences, just little things enabled by all of its touted features which makes playing games THAT much more intuitive and/or that much more involving. The touch screen for one will really streamline alot of game interfaces.
In Zelda theres the helpful dual screens so that we can have a constant map or whatever menu we choose, as the screen display can be context sensitive. Maybe they'll bring back Navi (I realize not everyone would be thrilled with this, but it beats "tingle") and have her populate one of the screens sorta the way a virtual pet does like 'Hey You Pikachu'. Theres the touch screen which likely will add all kinds of unique little twists to Zelda dungeon design. Maybe Link will find a homing boomerang that will arc out in a path you trace...or perhaps Link will cast magic by simply scrawling small shapes on the touch screen, like a small flame to light fires. Then theres voice technology, maybe the designers will add vocal puzzles where you have to to solve environmental challenges to learn a password to get to the boss room (like Lord of the Rings, "speak 'friend', and enter..")
Its in these subtle ways, smaller differences here and there, that may really add up to a compelling game experience.
