I have the original for the Gamecube, but I couldn't get myself to play it much...I dunno...I find the controls very limiting, thus making the gameplay experience a little primative imo. It was fantastic as a Playstation 1 original, but it doesn't do justice to the much superior Gamecube.
Though I would think bringing it to the DS would be in alike playing it on the PS 1, so in that sense it's probably more worth it.
Oh, and RE4 was
. A superb Gamecube original.
