You propel through space, your helmet rattling, heart pounding and arms flailing. Suddenly, a meteor zooms directly at you, out of the dark abyss. You fling your body to the left with all of your might, landing safely among the stars at the same time you land on your couch. You're in two worlds at once. They've blended together seamlessly. You lift your hand, and a spacecraft spurts to life somewhere deep within another galaxy. You brush your foot along your carpet, and a soccer ball flies into the net of a distant field surrounded by screaming fans. Somewhere along the way, the lines between your living room and the exotic, magical, dangerous and far-off worlds of your games have been blurred.
