Perhaps calls out is too harsh a phrase. Really Lucas Molyneux just asks, almost begs, Valve's Gabe Newell for more details on the perpetually not-finished Half-Life 3.
All the while Peter Molyneux, creator of Black & White, Magic Carpet, and Fable, peppers his son with advice and questions like, "What would you say to the Half-Life 3 team" and "Who makes better games? The Valve team or..." and "Buy Fable III not Half-Life 3."
OK Newell, the ball is most definitely in your court. Bring on the adorable, Newell-offspring response.
