I booted up my emulator and selected Robotron: 2084, one of my all-time favorite games. I’d always loved its frenetic pace and brutal simplicity. Robotron was all about instinct and reflexes. Playing old videogames never failed to clear my mind and set me at ease. If I was feeling depressed or frustrated about my lot in life, all I had to do was tap the Player One button, and my worries would instantly slip away as my mind focused itself on the relentless pixelated onslaught on the screen in front of me. There, inside the game’s two-dimensional universe, life was simple: It’s just you against the machine. Move with your left hand, shoot with your right, and try to stay alive as long as possible .
