Barring the Squeenix Final Fantasys and Chrono Cross which are expected to be good, the ones which first came to my mind were Wild Arms and Suikoden 2 Tales of Eternia, being a Tales Of game, is also great, and the remake of Tales of Phantasia on this console I think is the best version of that particular game Lunar and Lunar 2 were suprisingly nice too, despite being remakes of Sage Saturn games
