i should probably add star ocean to the list, since i seem to be addicted to it now...
Star Ocean- developed by tri-ace, and published by enix(now square enix of course), star ocean was a ground-breaking rpg. not only how it had a (kinda...) real time battle system, it used up 48 megabits of memory, the most a snes cartridge can store. it also featured in-battle voices, which is very amazing for a snes game

it has many different playable characters, and an item creation system, so yeah, it had a lot more than rpgs of the time. it also had a rather sci-fi themed story, although there are fantasy elements too. also, there are many possible endings depending on how you treat other characters.
it had three sequels: Star Ocean: The Second Story for the ps1, Star Ocean: Blue Sphere for the game boy color (which is kinda a side story to second story, but whatever), and Star Ocean: Till the End of Time, the game im currently addicted to><;; for the ps2.
all the games are set in the same universe, and although none of the characters seem to be related (unless you count puffy

), you can make a timeline of all the stories (did that make sense?) especially if you count the major plot twist in Till the End of Time, then you could say theyre all related

(find out yourself! =3)
i found some of my info from wikipedia and a plot analysis from gamefaqs...=3
