The Good: The graphics were amazing. They weren't kidding when people said that no reactions with the environment are the same. The two final boss fights (Darth Vader and either Darth Sidious to end on the light side or Vader again for the dark side) were the best. The Force powers are better than the other games.
The Bad: Most of the boss fights were unfortunatley easy and always involved some sort of trick to win. There were only nine missions in the PlayStation 3 version, and all of them short. It took me about two hours to beat. It left some things unexplained, like if you go over to the dark side what happens to you later, and other things like that.
