My 4-year old loves the lego.com website which has some great games (check out Junkbot, Junkbot Undercover, Worldbuilder, and Brick Buster). Yesterday he found the Knights' Kingdom Chess Set. We were both awestruck.
If you accidently type in "www.legos.com", you will get a not-terribly-friendly message from the folks at Lego reminding you that they are "LEGO bricks or toys", not "LEGOS" and kindly refrain from diluting their trademark. Apparently, I am not the only one who has noticed this, as Melody Wirz of Phosita writes this week (Lego my Legos) (via The Trademark Blog).
