A great game and a most worthy successor to LEGO Star Wars: The Video Game. The power bricks, bounty hunter levels and the ability to watch previously viewed cut-scenes are all good additions. Also, the levels are longer. If you bought the first LEGO Star Wars and don't have this one, then get it! You're missing out on a whole lot!
I had no problems installing it, except that it hung at one point before it continued.
