If you've ever enjoyed playing with LEGOs, you will probably find at least $20 worth of fun here. The vehicle stuff really sneaks up on you, and the game is just plain pleasant. Mission variety is less than amazing, but everything in between makes it worthwhile. For example, there is a mission that tasks you with razing the highest amount of dominoes with a single impact point. Sounds basic, but the true fun is in crafting the plan and the vehicle to solve the problem.
I'm not thrilled with terms like "GOTY," but I'd say it's among the most fun games I've played this generation. For reference, other favorites include Super Mario Galaxy and Crackdown.
