Final Fantasy: The first one. I want to see it with new graphics, in 3d, with it's story fleshed out a bit more, and with all the flair and flashy spell effects that Final Fantasy is known for. I don't want just a remake, I want a full reimagining.
Road Rash: The original games are always a blast to play, and a new one, almost done in the style of Split/Second with motorcycles and weapons, could be AMAZING.
Legend of the Mystical Ninja starring Goemon: This N64 gem is just begging for a remake, with all the zany skits and laugh tracks, and the giant mech on rollerskates that wants to be a pop star in America...
