It's a computer lab with whitewashed concrete-block walls; linoleum floor; a long row of blinds that are, of course, always closed. A group of long-haired coders in their mid-20s are gathered around the bright light of the screen. It's 3am, but no one wants to go home: they're all clamouring to play next. The two lucky enough to have the controls are holding their arms up, their elbows sore with repetitive strain injury from playing the game. "No!" they shout. "Turn! Fire! Argh."
