Thanks everyone! I think it's really cool that everyone has different opinions of which ones are our best. Keep it interesting for us!
I should say that Grandia III (which I've actually beaten) is a really fun game. If you've got a PS2 and some spare time, I'd recommend it. Granted some of the cinematics are... well, you saw. And occasionally a character falls into a plot hole and is never heard from again, but the battle system is just too much fun. And hey, it's better paced than Eternal Sonata!
