SENSIBLE SOFTWARE were a remarkable development studio who went onto have remarkable success with titles such as Sensible Soccer and Cannon Fodder. However back in the late 1980's they were just two guys, Jon Hare and Chris Yates. Jon Hare talks here about how game design back then was very much about what seemed right at that moment, they had never heard of game design documents at that stage and just made it up as they went. WIZBALL for Commodore 64 is a classic example of that process and how a strange and thoroughly original looking and playing game emerged.
