Great lego game, it is everything you expect from a lego game like characters with special abilities and secrets around entire map. I Didn't finished the game yet but I'm sure I will go back to every level just to get everything, no studs left behind.
My first thought when I got to the Bat cave was: "what the heck? only 3 chapters??" but then I discovered that there is 3 chapters as batman & robin and 3 chapters as villains (which I think are the best missions because you see what happened before Batman's chapters.
I Recommend this game to everyone, to batman fans, to non batman fans, kids, adults, granpas and grandmas... It isn't hard, but that doesn't mean it isn't fun. To myself the great challenge is to get everything from every mission and the max amount of studs I can get.
