What I'd love to see would be a hi-res pack of Rumiko Takahashi's characters (author of Ranma 1/2, Urusei Yatsura, etc). There are some Ranma fighters on this site, but they're all at about SNES quality (some of them I know are ripped from the SNES Ranma game). I know it's unlikely, but if somebody created some ArcSys-quality characters from Ranma or Urusei that'd just about make my day.
