I really enjoyed it, possibly more than the original. What I thought it improved on the most from the original was that the universe in the sequal was much more morally ambiguous, there wasn't necessarily a clear cut "right" or "wrong" thing to do in many instances.
Yeah, I have to agree with the first two responses. Definatly different than the other Star Wars games for the XBOX but definatly a keeper. Its just a whole different experience all around. For the price I've seen it in EB Games which I think is about $7.99 its definatly worth it.
