Many have mentioned the daily messages on your progress with the Wii are Nintendo's response to Microsoft Achievements. But I noticed that because they tell you how much you played each game, parents can screen their kids' playing habits to see if it's getting in the way of homework or other important things. It will also tell Mom if Sonny secretly borrowed that M-rated game from his friend. I haven't even delved into the actual parenting tools, because I have no children.
