The best sword-fighting game I've come across has been Defenders of the Crown. Very quick little fights, mess up three times and you die.
For an example of an original martial arts fighting game, Toribash is worth checking out and seems very interesting. My computer isn't powerful enough to play it though, so I can't give a review.
