I've actually given this a little thought, but to me, I think since Sabin is in many ways a carbon copy of Ryu... it would all come down to spirit. Who wants it more. And unless the planet is in danger from a maniacal lunatic (e.g., Kefka) Ryu won't be beaten by a 16-bit clone. (provided that Ryu has been around since the 8-bit days. The Original Street Fighter)
