This is a good game, lots of fun. but after you beat it, unlock all the characters, extras and the extra level...its just not as good as when you first play it.
Its good how you can play through all the episodes (well 1,2,3 and one part of episode 4, but you have to unlock that)
Its also fun all the characters you can unlock and play as: from yoda to jar jar, general grievous to chewbacca...and...well i think you get the idea.
but as i say, its fun the first few times around but then just gets boring....so rent it first (it doesnt take that long to beat) but its still a fun game
