6.5? That's funny, that's the score I give Gamespot.
Do yourself a favor and ignore that score, bleh just ignore GS in general, they have the dumbest people reviewing rpgs I swear to God.
Anyway, pick this up any way you can, it's truly one of the greatest rpgs of all time. It was a completely innovative and original game when it first came out and it doesn't disappoint. I don't even know where to begin, should I talk about just how simply amazing the story and characters are? The fantastic battle system? The build your castle feature? There's just so much to like here you'll have trouble pinning it down to any ONE thing.
You can grab this game from a bargain bin now for around 10-15$, maybe even cheaper, so there's no reason not to experience it if you haven't already. And that's exactly what it is, an experience through and through. Don't miss it.
