It's a great game. They added more gaming options than the first game had ( the OT better than the PT? Who could have guessed?.....).
You can port a save over from the first game so you have another 50 chars to play with, has adaptive hardness you can switch on, can play special bounty hunter levels, timed runs of special levels where you try to collect 1 million studs, speed runs of all the levels for each movie together, special levels using the mini space ships, plus the mix and match option to make your own chars using the parts of other chars( i.e. red lightsaber gives a char sith powers). On top of the studs which the first game had, LSW2 has gold and red bricks to collect as well, which open other levels.
You can also play any of the cutscenes when you are back in the Cantina after you have opened them. I think there are about 60 of those when you are finished, some of which run for a couple of minutes by themselves.
Much to do.
