Chrono Cross? Good? *pukes in mouth* that game sullies the genius that was Chrono Trigger, I refuse to accept that *censorship for the good of the children* as a sequel of any kind.
Anyway, that aside...
I suggest Tales of Symphonia for the Gamecube, for two reasons alone... Presea and Sheena <3
Odins Sphere is also great, I love the story and characters of this game.
Mana Khemia is good too, I rather enjoy the humor in the game. especially Anna's scenes
Persona 3 FES is also good. Although, the ending left a bitter taste in my mouth... you might like it though.
I generally hate all things Final Fantasy after FF6, well I like 7 sorta, so.. I won't make any comments about it.
Suikoden 2... if you're willing to dish out 250 - 600 bucks for it... lol. I found a mint condition unopened Suikoden 2 for 600 dollars. I picked mine up when it first released on a whim... I just thought the cover was cool and bought it, best decision I ever made.
