Absolulty dreadful!
All I can say is what a disappointment! The graphics were poor and so was the gameplay, quite frankly I was amazed that the actual cast of the original Star Trek's voices were used to play their characters, not the best career move I think! I would have been ashamed to put my voice to this mediocre attempt of a video game...
The once good thing that I can say about it though is that I always loved the design and look of the Enterprise and being able to fly around it and shoot phases ans stuff is pretty cool, but that's about it...
