Way I hear it told the main boss is a chap named Night Terror. Haven't fought him myself, but accounts suggest they've gone to the old-school idea of having to never lose a match, and having to pick exactly the correct choices when you get them, so I'm not terribly surprised I've not seen him if he's real.

I really like the new characters. Tira is pretty spiffy, but Zas and Setsuka are very, very awesome.

I love what they've done with Voldo, he's even better now. And he was pretty powerful beforehand. I'm also glad they made Cassandra better, and cuter for that matter. It was a no-brainer between her and Sophitia in II.
