Sex always drives the leading edge of technology, so it should be no surprise that one of the cutting-edge videogames was Softporn, a text-adventure for your penis. It was designed by a computer programmer, but bought and distributed by one of the biggest adventure-style game developers at the time. That sexy, topless woman on the right? One of the greatest minds in puzzle-adventure games. Later, Sierra used more advanced computer technology, added graphics and animation, and rebranded Softporn as Leisure Suit Larry.
