So, I have this idea for a short story. It's basically a father discovering that his son has started playing a new and involved game. In an effort to be a better parent, he decides to start playing himself... and becomes the first adult to discover that some of the more wildly fanciful elements that his son has told him about (talking game-pieces, otherworldly battles, etc.) are true.
...And then he has to decide what to do about it.
