Because about four weeks ago, the world simply turned. One day we had iPhones and GoPros, Mickey Mouse and hamburgers. The next day we had magic and monsters. And us humans? We became players with levels, items, and classes. Pretty ironic considering how many times my parents told me to “quit gaming and experience real life” while I was growing up. And then real life grabbed us by the balls, and it was the gamers who were prepared.

Discover William Tenn's brilliantly satirical science fiction classic Venus is a Man's World, where gender roles are hilariously reversed.
