Jade Empire - 9/10
Very similar to Kotor, but not quite as good.
Warning - Invisible spoilers ahead.
The game's main strengths are its story (Something Bioware always seems to do well) and it's characters, which are inventive, funny and occasionally Monty Pythons. And of course, it's very much like Kotor.
One of the weaknesses is, unfortunately, that it's veyr much like Kotor. Even down to the Light Side/Dark Side Points scale, which has become the Way of the Open Palm or the Closed Fist.
The biggest problem is that it's too short and too easy. The most challenging fight for me came right at the beginning on the beach when my health was low. And it only took me about 17 hours, as opposed to the 30+ a good Kotoring will take.
