I got the Wii version and I must say I was pretty disappointed in it.
While it was enjoyable too many things were taken out of the players control. For example when your fighting someone and their health is low it keeps trying to force you in to a cut-scene that involves you shaking and twristing either the Wii-mote or the nun-chuck, which takes away they joy of taking someone down with your own skill instead of just shake now, twist, shake, done. All it should be noted that towards the end this starts to fail as when you get the Wii-more in the right postion it says its locked in the right postion, but isn't really.
Another fault I have is the strength of the enemies, mainly the Stormies. I know that this is surpose to make the game more challenging as it goes on but come, how the Hell can I Stormtrooper servive being thrown in to a wall and then slashed 3 times with a Lightsaber?
Oh and as for the Star Destroyer part, all I can remember getting was a cut-scene.
The games enjoyable, but I would have personaly prefered it if it had of been more like the Jedi Knight games, except with better graphics and the ability to destroy everything.
