I think the only kind of game your kids would be interested in are computer games and I know nothing about what makes those games interesting or "fun"; they leave me cold, I'm just the wrong age and/or temperament for them.

I doubt I would have anything intelligent to say, but if you have questions I would be glad to try and answer.

Meanwhile, I think you might enjoy reading the book "Critical Play" by Mary Flanagan that I cited above, given your background in games, art history, design and activism.

She also has a chapter in the Zones of Control anthology; I'm glad to share a table of contents with her.
