Grandia 2? You got to be very deprived of games then. Don't get me wrong, it IS your opinion, and grandia 2 was a nice game. But Grandia 2 was too easy, lacked creativity in bosses, also the last boss was a joke, the plot was or seemed jumbled. All in all, grandia 2 was average. I'm surprised you rather not choose Chrono Trigger as that game was great!
Oh, back to the topic. Too many good ones to choose from.
