Tales of Symphonia is a 4-part OVA...starting very soon if not already. Just waiting on an English sub-group to pick it up!
Another awsome game was
Shining Tears, which is now an anime currently airing. I'm watching it and my current siggy is all Shining Tears......but unfortunately it did horrible sales wise in the US. If you can find a copy of this game for PS2, I highly recommend you play it....don't listen to reviewers...they hated it because there was no voice, and it was a 2D game!
