If you love the Star Wars series you will probably love this - everyone else should purchase with warning.
First - let me start by saying this game WAS a lot of fun...reminded me of platformer gaming and the star wars theme was fun to be involved in.
With that said - Star Wars them set aside, the game was pretty linear and didnt offer much past the fact that you were playing thru the star wars script with legos. At times the controls were a tad sloppy and searching for correct boxes, etc to smash got redunant.
To be honest I never finished this game which is probably why I am grading it lower than most. There just wasnt a lot there to keep me coming back. As far as the platformer/action adventure genre goes there were just a lot better options then and now.
Basically in short, if you are desperate for a fun game related to star wars this is it - if you want an action adventure game and star wars isnt a necessity...look elsewhere.
