Some days I spent up to three hours in the arcade after school, dimly aware that we were the first people, ever, to be doing these things. We were feeling something they never had - a physical link into the world of the fictional - through the skeletal muscles of the arm to the joystick to the tiny person on the screen, a person in an imagined world. It was crude but real. We'd fashioned an outpost in the hostile, inaccessible world of the imagination, like dangling a bathysphere into the crushing dark of the deep ocean, a realm hitherto inaccessible to humankind. This is what games had become. Computers had their origin in military cryptography - in a sense, every computer game represents the commandeering of a military code-breaking apparatus for purposes of human expression. We'd done that, taken that idea and turned it into a thing its creators never imagined, our own incandescent mythology.
