I don't care how strange Kojima's games are—they're all worthwhile because they remind you of the untapped potential of the medium. My favorite Kojima game? Probably Boktai, the Sun Is in Your Hand, a vampire-hunting game for the Gameboy Advance portable device. Kojima's innovation was to equip the game cartridge with a photometric light sensor, which needs direct sunlight in order to recharge the solar gun you use to zap bloodsuckers. As I played it in the park on a typically foggy San Francisco day, I got so wrapped up in the game that I stood on a bench with my arms skyward to catch as many rays as I could—a grown man in public holding a Gameboy aloft like John Cusack with his boombox in Say Anything.
