This game would have been awesome if you played as vader throughout the entire game and hunted down the remaining jedi. You Know what episode III should have been, and what got basically moved to the Dark Horse comics purge.
But of course the clone wars and jedi purge had to be told in a multitude of media to maximize profits. It is all about the greenbacks for Lucas, the story is completely secondary hell you don't need a script as long as you have cgi,lol.
