Saber battles seem to alternate between impossible and way too easy, depending on when you activate force speed. I also could never maintain my shields. I'm glad I had force heal level 2 or I would have been toast in some of those two-on-one and three-on-one saber fights. (Of course, it would help if I would NOT run right up and impale myself on my enemies' saber...) Two sabers is fun, though not as fun as I thought it might be. Didn't try saber staff. Had to save every two minutes, that's a bit annoying.
All in all, I recommend it if you can get it on CDROM from someone. It's a hell of a download to do yourself though. If you liked Jedi Outcast, this seems to be a worthy successor.
