No Export for You: The PC port of Silver Star Story, which does have higher resolution than the PlayStation and Sega Saturn versions and better video playback for the FMV cutscenes, but the port was only released in Japan and South Korea. An English version of the port was planned, but it was too buggy and unstable to be made.
The Other Darrin: Only five characters (Alexnote Kikuko Inoue, Lunanote also Kikuko Inoue, Nallnote Rei Sakuma, Quarknote Koichi Kitamura, and Ghaleonnote Rokurō Naya) speak in The Silver Star. When Silver Star Story was made, those five all got different voice actors in the Japanese versionnote Akira Ishida voiced Alex, Kyoko Hikami voiced Luna, Junko Hagimori voiced Nall, Yusaku Yara voiced Quark, and Kiyoyuki Yanada voiced Ghaleon.
Meanwhile, the five English actors who did The Silver Star (Ashley Angel, Rhonda Gibson, Jackie Powers, Hal Delahousse, and John Truitt) returned for Silver Star Story along with a slew of new actors for the other characters. The English roster changed completely when Silver Star Harmony was released.
