3. LEGO STAR WARS Wii
I have a 3-year-old who's obsessed with Star Wars. On his birthday, he got the Lego Star Wars Wii game, and what was I supposed to do when he begged me one lazy afternoon to play with him (and the book I was reading at that time was chock full of boring expositions)? So we played. Do you know that the Jedis can do really cool lightsaber moves? And they can jump really high? Do you know that after every chapter you're given a True Jedi rating (for not dying so much during the game)? Do you know there are cheat codes you can find in the Internet if you know where to look, or field guides when you're stuck in a particular episode?
