To say "this was not easy" is an understatement. This was 1993, remember. Game programming in academia was a new idea, it was groundbreaking, it was a paradigm shift of epic proportions. It was so far out of the box that I couldn't see the box at all from where I was standing. Not only did I not have the required skill-set, it wasn't even clear what the skill-set was. As a theoretician I was totally unprepared, but then so was the rest of the world. What the hell, I had tenure.
