Excellent, excellent, excellent!!
Just about everything. 3-D interfaces, story presentation, graphics and sound, and most of all, the awesome music. I could listen to choral voices accompanying the "Death of Kharak" mission all day. Enemy AI is crisp, and took me by surprise on any number of occasions.
Limited replayability due to the fact that both races use the same mission, only with different ships. I found it kinda disheartening to find the Taidan taking up the same noble cause I just finished up with the Kushan. I wanted to squash the Kushan with my imperial might!
The Bottom Line
Play this game! You will undoubtedly be enriched by it. (Gaming-wise that is :))
