My review of LEGO Star Wars II is up on SCIFI.com. I enjoyed the game alot; it's perhaps the first game for the Xbox 360 that I really love, though that's not saying much for the 360 since the game's available on, well, every other freaking platform out there.
The game has also inspired a sort of Star Wars awakening in my three-year-old daughter Jordan, who was previously terrified of the series thanks to the Darth Vader trailers for Episode III. Watching my play LEGO Star Wars, she's really gotten into the story (which I have to explain to her, since there's no dialouge). It helps that LEGOs are innately harmless (even Vader is cute rather than menacing) and it has a Princess (and Jordie is all about the princesses).
I've been careful not to reveal too much of the story to her, since I would like her to watch the movies some day, but at least now she tells me to hush when I mention Star Wars. Moreover, this is a game we can play together ... once I get a second controller. I've already created a purple-cloak, pink tunic-wearing, purple lightsaber wielding version of Princess Leia for her, which she thinks is just too darn cool.
