I don’t remember how we learned about it, but a friend and I learn about the D&D 4E starter red box and decided to buy it. I hadn’t played since I was a teenager (even then I only played maybe 2 sessions), and my friend played only a year or so ago somewhat regularly with a mutual friend. We pulled in two other friends who were new to D&D, and got started. As I was hosting, I decided to be DM, with the idea that we would shuffle around the role. First two sessions are long but fun as we learn (or re-learn) the ropes of 4E.
