I am really lucky to have kids who rarely say they are bored. However, I've noticed DS has a much harder time finding something he finds fun after playing MC for a long time; that's when I often hear him complaining of boredom (and no, rarely can I come up with an activity he's interested in.)

While I'm definitely not an anti-computer game mom, I do sometimes worry that they make things too easy. Creating in MC is pretty easy, as far as I can tell. Creating in real life takes more time and effort, and doesn't always garner the results you were hoping for. After the excitement and ease of creating in MC, I can see how the real world would seem difficult and flat.
