Very nice list. With your permission Clephas here are some suggestions of the era PS2 / GC / XBOX.
Dragon Quest the journey of the cursed king: A very rewarding game, turn based and hard!! xD
Baten Kaitos: A very "unique game", card system combat very fun to play.
Valkyrie profile silmeria/lenneth: Just play it, i love those games.
Tales of symphonia: wath to say here? a master piece.
Dark chronicle: the sequel of dark cloud. This game is "UNIQUE", a great system for weapons devolpment.
Star Ocean till the end of time: a wonderfull game with a lots of endings.
Wild arms 3: Bad graphics but... magic and western? awesome
I'll add some more later, i'll be thinking in add a few action rpgs but not sure if that's what you want so i dont do it. Again a very cool list... nice times those... xD
