I'm lucky enough to have an import copy. While in my memory it's a brilliant game, I did play it briefly recently and it hadn't aged well. The visuals were lovely at the time, but aren't great now. But it's not a bad game by any means, and if you love the series, then try picking up a US PS2 to play it, that would make things a little easier. I have a chipped original that plays any PS2 game from anywhere.
Grandia III is one game that has been on my EG "Most Wanted" list for years (I refuse to move it until its released here), I've been thinking about getting that Swap Magic whatsit just to import it and play.
Grandia - been away for far too long.
