Mario Bros by Nintendo. Turtles, crabs, and flies come pouring out of the waterworks. Hit the floor beneath them to flip them over, then kick them into the water. Collect coins for bonus points. Clic image for Video.
Gorf is probably the greatest arcade game ever. Such a nice cabinet too. It was my first pistol grip joystick game. I wouldn't have noticed it as a kid except fr the fact it spoke. Heck taunted me with "space cadet".
