I can't strees enough how wonderful Suikoden series is, even its worst game, Suikoden IV is a better game than most RPGs.

I really suggest you play Suikoden III, its magnificent, but since that is not on you list then I suggest Chrono Cross. Its a beautifully made game with a casty of decent characters. Like it was said above, don't go in thinking its as good as Chrono Trigger but its excellent on its own. You'll learn to love Serge and Karsh. Karsh rules.
