There are really two approaches to gaming with children. Method A involves using modern technology to supplement the tabletop game experience. To wit, you plunk a movie into the VCR and then game while the kiddie is distracted.
Some people find this method less than satisfying. "Gee, let's enjoy a time-honored rich oral tradition of storytelling and social interactivity-- but first, let me distract the kid with commercial-laden pap." So, for those 'gaming purists', we look at Method B, a time- honored way to run a game with the kids actually participating.
So the fundamental question becomes: given that we'll have less time for gaming ourselves, can we make up for that by raising a gaming child to increase the ranks?
