Fun platforming, a good distraction from all the shooters.
The most important thing the game gave me was a break from the barrage of shooters (1st and 3rd person) available for the 360.
The best part of the game is playing with a friend and, although online multiplayer through Live is not offered, local is as fun as always. Besides, it encourages social interaction! The multiple characters and myriad of levels provided good fun for hours. The achievements are great (although some are pretty tough), and the collecting in the game is a great challenge.
I encourage anyone wishing for some action/platforming to pick it up. The camera may be difficult sometimes and characters slide off of cliffs, but hey, they are Lego and cliffs have no studs to lock on to!
