Later on, in my teens, I built model airplanes and boats. I was never very good with my hands, but I did this with my school friend John McClenahan, who was much better and whose father had a workshop in their house. My aim was always to build working models that I could control. I think it was the same drive that led me to invent a series of very complicated games with another school friend, Roger Ferneyhough. There was a manufacturing game, complete with factories in which units of different colors were made, roads and railways on which they were carried, and a stock market. There was a war game, played on a board of four thousand squares, and even a feudal game, in which each player was a whole dynasty, with a family tree.
