As an avid Star Wars fan I felt that Drew Karpyshyn did an amazing job capturing the goings of the Old Republic and the Sith Empire itself. The story lines and their mergence were amazing and very eventful to the point that I couldn't put it down. 
 Despite the harsh criticism it gets from the fans that play the games, I don't feel like they give it enough love because of the combination of the game and the storyline but I feel that it goes beyond what it should to continue the story of the Old Republic. I think that Karpyshyn really took from the game and continued what fans didn't think of, how Revan continues after the end of the game and that's really what brings a huge interest for me. 
 As a Star Wars fan I highly recommend the book as everything you love about Star Wars genre is in there. If you are a hard core gamer I would give the warning of be prepared to extend what you've played.
