Love this game. Brought back memories and challenged me as well.
My kids loved watching and playing along as well (7, 4 & 2 years old). they didn't know what they were doing, but they liked it. It actually got us to sit down and watch the original trilogy again (and that's never a bad thing).
As for the game, it wasn't too difficult, but not a pushover either. Trying to obtain undeafeted is really a hard job. But I could play this thing over and over. The puzzle solving keeps you on your toes and the overall gameplay is quite invloved. Re-playing the missions to attain accomplishments is fun too. I would recomend this game to any Star Wars fan, as well as the Complete Saga.
