The best RPG in the Genesis, bar none.
It has a great plot, great characters, great music, and "comic book style" intermissions.
Its many references to the previous Phantasy Stars give the game a sense of history.
My only complaint about this game is that many of the names are inconsistent with the ones in Phantasy Star I.
By the way, this site does not do the game justice.
