Also, the voice acting changed around far too much for my tastes; KOS-MOS went from female android to valley girl (I exaggerate just a little), and chaos went from a calm, kind "young" man to a moody-sounding, monotone teenager. That being said, I think chaos's new voice was more appropriate to the overall character, but the sudden change was just too much of a distraction through the early parts of II's storytelling.
The story was fantastic, continuing on from the first and creating more questions than answers. The big problem I saw story-wise, though, was that Part II's story came to a close too quickly. My understanding was that they were trying to get the game out as quickly as possible, so they pushed off some story elements to Part III that should have been in II.
Had they taken their time with this game and gotten it right, I'd bet there would indeed have been Xenosaga Parts IV and V, as originally promised. II put off too many of the fans, I think, which is what probably most helped kill the series prematurely.
Anyway, to answer your original question, if you liked the story of Part I, you will like Part II. I can't guarantee you'll like the gameplay, but if you ever plan to play Part III (which I HIGHLY recommend), you should definitely play through II.
