This is my favorite arcade game of all time:
It was just the most incredibly over the top game ever. First it would take a picture of you with a little camera over the screen, which would then be the avatar for your "team". Then, you and a friend would basically face off in a match of Gundam Paintball. The controller was a huge gun mounted on top of a joystick that would move along x-y axes, and you'd move them around by moving the gun. Man, it was a blast.
Thank you Namco.
