Serious Gaming Starts at 6

As if parents didn't have enough to worry about, now we need to worry about this? I wonder if the number increases if both parents are serious gamers. Not that I'm hard-core myself but I am addicted to Yahoo Games and I have a desktop full of 1-hr downloads. Chris on the other hand is a hard-core gamer both online and offline (Halo, anyone?) so that makes me wonder how our children will fare in the long-run.
