Nintendo has already has a Zelda on the ds planed but it’s just another Four Swords, I want a better experience….

Features I have had the idea for are listed here:
“Me: lol I think we need to see more tunics in the games maybe in the Ds version you will be able to make the colour you want your player to be

BSG: You know what...that could be a possibility. I've heard that the DS will come out with a Pac-Man game where you can draw your own Pac-Man character and play as it! I don't know if that will work out with Zelda, but who cares, it's a possibility that could happen.

Me: hmm.... it could the way the Ds work have you seen animal crossing Ds how you can make an image and it will be on your clothes?
That’s what I mean but more like the colour like say I press start or something look through the menus find the clothes edit room edit the colour of the clothes then save and exit the menu.

VG: dude man, its the cap that makes the Link. And trinest thats a really awesome idea. I assume that they're many people out their who would not like to play as a purple link, and their are many out their who would like to play as a black tunic-ed Link”

Another possible thing is a new world while Zelda dose rescale old places and worlds this will be ether a new one or Cresent Island.
There are many more features and possibilities for Zelda Ds
