By far one of the strangest "MMO"s I've come across, Massively Multiplayer Pong is an exercise in too many cooks tending the soup. It runs in a flash player and you and - at my last count - 18 other people control one of the iconic Pong paddles while another bunch of work-evaders control the other. Not for control freaks.
I was please to see, however, that my team was winning 8,435 to 7,040.
