Just beat Summon Night 2. Morlin End, 'cause she's cool.
Not as good a game as the first I think, though they did learn some lessons.
Most everyone that can join you does so no later than halfway, and as if to make up for what happened last game, some of the people do return for the second game, except they join in the first half of the game, rather than the last two chapters.
Other than that, I just think the game was too long (it could've been condensed), and as always, too many characters. This causes some air time issues, where screen time has to be divided among way to many characters, and only two other characters ever see development. Morlin never finds her dad, Keina never gets her memory back... If you fast forward seven years, Flight-Plan kept getting better at this. (Dragon Shadow Spell didn't really suffer from any of these.) They've closed their doors, though... ;_;
