Great game with a lot of great material to work with.
I've not played alot of platformers (generally I'm a PC gamer, FPS and .. well.. er... tactical FPS :) but I've enjoyed some of these on the 360 because my kids can play, too. Star Wars is one of my favourite movie series of all time, IV-VI in particular, and this game plays through the best scenes of each movie. The characters are lego, but with fun personality twists in the cutscenes and it's all good fun. The graphics are fine and the sound is great (love that musical score!!). The levels are easy enough to "just get through", but I've sometimes more than an hour apiece hunting around for the little extras to really complete them.
All in all, this is a great family game... actually it's just a great game.
