Galaga

You ever notice how Galaga fans get that glazed look when they talk about dodging alien attacks like they're dodging responsibilities? This game is the secret handshake of the arcade elite; nothing says 'I peaked in the '80s' like a high score on this bad boy. It's in the Greatest Classic Arcade Games league because where else can you blast bugs and claim it’s a strategic life choice? The addiction level? Let's just say there’s a thin line between hobby and calling in sick to break your high score.
